Since the past, humans have encountered many types of viruses, epidemics, and pandemics, and are currently battling an outbreak of a deadly disease called Coronavirus Disease 2019 (COVID-19).
Coronavirus disease 2019 (COVID-19) was first reported in Wuhan, China, on 31 December 2019. On 30 January 2020, the Director-General of the World Health Organization (WHO) declared the outbreak of COVID-19 a public health emergency. And on 11 March 2020, COVID-19 was declared a global pandemic by the WHO.
To better understand the Coronavirus Disease 2019 (COVID-19), here at healthroid, we analyzed 3.74 million words of content, smashed them together, shook them up, and came up with some astonishing insights. Our focus was to understand exactly how Coronavirus spreads and how it can affect your health.
And now it’s time to share what we discovered.
In this comprehensive guide, you will learn everything you need to know about COVID-19, from SARS-CoV-2 basics to COVID-19 symptoms to its spread to its prevention to its treatment.
And by the end of this guide, you will get answers to all the questions that are arising in your mind right now.
So without further ado, let’s dive right in.
People without thinking and without studying are making comments on social media that “coronavirus is just a common cold.”
Yes, cold is an early symptom of novel coronavirus infection, but that does not mean that coronavirus is just that. Therefore, to understand the coronavirus completely, it is important to know its history first.
Coronavirus is a family of viruses, which, when viewed from the microscope, crown, or halo-like spikes are seen on their surface.
According to the Centers for Disease Control and Prevention (CDC), the first human coronavirus was seen in the mid-1960s. After that, seven such coronaviruses have been identified that can infect humans.
The four coronaviruses that are common and not too dangerous are:
These four viruses usually cause common cold in humans, and almost all people, at least once in their lives, are definitely infected with one or more of these viruses.
Coronavirus fact: There is no cure for the common cold.
Then, three coronaviruses can cause great harm to humans:
Let us first tell you about these three diseases in brief:
Severe Acute Respiratory Syndrome (SARS), a viral respiratory illness caused by the SARS-CoV virus, was first seen in China in 2003.
Middle East Respiratory Syndrome (MERS), a viral respiratory illness caused by the MERS-CoV virus, was first seen in Saudi Arabia in 2012.
Corona Virus Disease-2019 (COVID-19) is an infectious disease caused by novel coronavirus (SARS-CoV-2), was first seen in Wuhan, China, in mid November 2019.
Coronavirus fact: We are still in the mid stages of the COVID-19 outbreak, and unlike any other common cold, there is currently no medication or vaccine available to prevent or treat this new virus.
You must be thinking, how dangerous is this COVID-19 outbreak, and how much should you worry about it?
Well, for this analysis, we analyzed some worst coronavirus outbreaks in history and compared them with the current ongoing COVID-19 outbreak.
For your information, below we are listing the ten worst virus outbreaks of history so far:
Name | Year | Infected | Death | Fatality Rate |
---|---|---|---|---|
Marburg | 1967 | 590 | 478 | 81% |
Ebola | 1976 | 33,687 | 14,693 | 44% |
Nipah | 1999 | 496 | 265 | 53% |
SARS | 2002 | 8,098 | 774 | 10% |
H5N1-Bird Flu | 2003 | 861 | 455 | 53% |
A(H1N1)pdm09 | 2009 | ~1 Million | ~203,000 | 1 to 10,000 Deaths/ 100,000 People |
MERS | 2012 | 2,494 | 858 | 35% |
H7N9-Bird Flu | 2013 | 1,568 | 616 | 39% |
Seasonal Flu | Yearly | ~1 Billion | 290,000- 650,000 | 10 Deaths/ 100,000 People |
COVID-19 | 2019-Ongoing | 7,092,919 | 406,207 | 5.72% |
Severe Acute Respiratory Syndrome (SARS), which was first identified in 2002, had about 8098 people infected, of which around 774 people died. This coronavirus outbreak had a fatality rate of about 10 percent.
Similarly, about 2494 people were infected with the Middle East Respiratory Syndrome (MERS), which was first identified in 2012, out of which around 858 people died. The fatality rate of this coronavirus outbreak is much higher than SARS, which is close to 35 percent.
And currently, 7,092,919 people have been infected from the ongoing Corona Virus Disease-2019 (COVID-19) from December 2019 to June 8, 2020, out of which about 406,207 have died. And COVID-19 currently has a fatality rate of around 5.72%.
And if we compare these three coronavirus outbreaks then we get the following data:
Although the fatality rate of COVID-19 is lower than that of SARS and MERS, the nature of this virus indicates that it is growing very rapidly.
To understand the increasing number of infections from the COVID-19 outbreak, we have created a line graph for you.
According to the WHO’s COVID-2019 situation reports, the number of people affected on January 21, 2020, which was 282, the same number increased to 76,769 on February 21, 2020, next month, and not only that, this number was later expanded to 4,893,186 in just four months.
That means about a 17351% increase in the number of infected people in just 4 months.
Isn’t that HUGE?
Well, don’t look at the digits, but try to understand how fast the number of people infected with COVID-19 is increasing by looking at the graph.
Day by day, along with the number of people infected with COVID-19, the number of dead is also increasing.
According to the same situation report of WHO, the number of people who died from COVID-19 which was only 3 on January 21, the same number increased to 2247 on February 21 next month and not only this, in just four months, the number of dead has touched the figure of 323,256.
Which shows a fatality rate of about 6.60 percent.
Coronavirus update: The death rate which was close to 2.5 percent in the initial 4 weeks has now risen to 6.60 percent.
Here is the line graph which describes the current situation very well:
This line graph displays the current confirmed cases (in blue), deaths (in red), and recovered cases (in green).
The WHO has repeatedly underlined the importance of “flattening the curve” in order to tackle the coronavirus outbreak. But looking at the curve, it does not seem that the situation is under control.
In fact, as of now, out of every 100 infected people, at least 6 to 7 people are dying due to COVID-19.
You may find this fatality rate lower than SARS and MERS, but the pace with which COVID-19 is infecting people, it is possible that in the coming few months, tens of millions of people will be affected by this virus. (which is actually happening)
In fact, the World Health Organization has said that it may take about 18 months to prepare a COVID-19 vaccine.
This means that all countries will have to use their already available resources until the vaccine of COVID-19 is made.
So in such a situation, the responsibility of protecting yourself from infection remains your own. And how you can prevent your coronavirus infection, we will mention it in the upcoming chapters of this guide.
So let’s move ahead now.
In late December 2019, China’s public health officials informed the World Health Organization about an unknown virus that is causing diseases like pneumonia in people.
And the following week, on 7 January, the WHO announced that the pneumonia outbreak in Wuhan city of China is due to a newly emerging virus of the coronavirus family. They also added the virus is spreading rapidly in and out of the city.
Since then, medical scientists around the world have been trying to find out where the new coronavirus came from. Many of them believe that the origin of this outbreak can be the Huanan Seafood Wholesale Market.
COVID-19 Update: China informed the WHO about the disease in late December 2019. However, there's now evidence which suggests it actually began in November.
According to a report by The Lancet, as of January 2, 2020, in Wuhan, 41 patients admitted to the hospital were found to be infected with COVID-19, and 27 of them had direct contact with the Huanan Seafood Wholesale Market.
Researchers believe the COVID-19 infection spread to humans from animals being sold in Huanan Seafood Wholesale Market.
In further observation, samples of animals of the market were also taken between January 1 to January 12. And at the end of the month, the Chinese Center for Disease Control and Prevention made it clear that 33 out of 585 animal specimens were infected with the coronavirus.
Even after discovering that COVID-19 has been transmitted from animal to human, it is unclear what type of animal the virus originated from.
A research team from China, looking at the genetic code of the virus, claimed that the coronavirus came from snakes. While in another analysis, it was found that the genetic sequence of this new virus matches 96 percent of the coronavirus found in the bats.
Considering both these analyses, for coronavirus outbreak, either of the snakes and bats can be considered as a culprit. And, since some snakes eat bats, bats are probably supposed to be the origin.
But, to be fair, snakes and bats have not tried to spread this disease, but humans have bought them from live animal markets to feed their hunger and have themselves become the victim of infection.
Therefore, to not have such outbreaks in the future, it is necessary to ban such live animal markets across the world.
COVID-19 Update: On February 7, 2020, researchers in Guangzhou, China, suggested that pangolins can be the most probable animal source of the coronavirus outbreak.
Researchers have already suggested that COVID-19 originally came from bats. But the virus was probably transmitted to humans by another animal.
Yes, you heard that right.
In a research jointly conducted by Shen Yongyi and Xiao Lihua of South China Agricultural University in Guangzhou, shows that pangolins are the potential intermediate host for a new type of coronavirus. According to their research, the genetic sequence of the virus found in pangolins had 99% similarity with the genetics of new coronavirus.
Whether the pangolin was the species at which coronavirus jumped, it’s not clear. So in a study, virome data sets of pangolins and bats were reanalyzed in which it was found that the samples of bats were more similar to the SARS-CoV-2 virus than to the pangolin coronavirus.
Therefore, it is certain that the primary origin of coronavirus are bats. But if we believe that pangolins are also involved in coronavirus spread then, the virus may have jumped from bats first into pangolins and later from pangolins into humans.
But what is the connection between Pangolins and China? Let’s understand:
Pangolins are the only mammals wholly-covered in scales- which they use to protect themselves from predators in the wild.
In China, traditional medicines are made from scales of Pangolins, which are used to treat problems like arthritis, menstrual pain, and skin conditions. Not only this, pangolin meat and blood are considered a delicacy in China.
This is why Pangolins are in high demand in China.
But do you know that Pangolins are a very rare and endangered species of mammals? They are one of the protected species under national and international laws. In China, if a person is found selling Pangolins in any way, he can be imprisoned for up to 10 years.
So the question arises that despite such strict rules, how are the people of China fulfilling the demand for rare and endangered Pangolins?
Well, the answer is very simple: illegal poaching and trafficking of Pangolins.
According to the South China Morning Post, the population of pangolin has decreased by 90 percent in China from 1960 to 2004, due to the commercialization of pangolin.
Although officially, it is not possible to sell pangolin in the Hunan seafood wholesale market. But it may be possible that due to the high demand for pangolin, people are selling them in the market illegally.
And what if the illegally sold pangolins are already infected with coronavirus? Yes, it is possible.
According to a research report published on 24 October 2019, coronavirus is probably responsible for killing a large number of Malayan pangolins.
So it is possible that the pangolins being sold in the market may be one of them which may not have died at that time but have been infected with the coronavirus.
Therefore, looking at the facts, it can be concluded that in the Hunan Seafood Wholesale Market, people were illegally selling “coronavirus infected pangolins” along with other animals without the intention of harming anyone.
And accidentally, the coronavirus outbreak happened from there.
And if, in reality, illegal animal trade is the reason for the coronavirus outbreak, then it will be challenging to get to the root of the virus outbreak because people may have already erased all the evidence from the market for fear of being caught in illegal trading.
Looking at the first cases of COVID-19, it seemed that the disease is not as severe as SARS and MERS. But the increasing number of confirmed cases of COVID-19 and evidence of human-to-human transmission of the virus proved that the novel coronavirus (SARS-CoV-2) is more contagious than the other two coronaviruses SARS-CoV and MERS-CoV.
To find out how dangerous this coronavirus is for different individuals, China’s health officials released a report in which they conducted in-depth study of 44,672 confirmed cases of COVID-19 in Mainland China as of February 11, 2020.
To our knowledge, this is the first most significant study since the coronavirus outbreak.
And now it’s time to share what they discovered. Here’s the summary of their key findings:
We have detailed data and information on the analysis below.
The analysis included a total of 72,314 unique records as of February 11, 2020, out of which 44,672 cases were confirmed to be infected with the coronavirus.
According to the analysis, out of 44,672 confirmed cases, a total of 1,023 deaths occurred at a 2.3% fatality rate.
To better understand the pattern of SARS-CoV-2, below, we have explained the analysis with the help of graphs in 7 different parts. Which are as follows:
In the analysis, there are 9 different classes of people according to age, in which 0–9 years, 10–19 years, 20–29 years, 30–39 years, 40–49 years, 50–59 years, 60–69 years, 70–79 years, and ≥80 years old people are included.
The study shows people aged 30 years to 79 years are the top in the list of confirmed cases of COVID-19.
According to the study, 50–59 years is the most COVID-19 affected age group (with 22.4% of people). While, 60–69 years (19.2%), 40–49 years (19.2%), 30–39 years (17.0%) age groups are also fairly affected.
However, if you look up the graph, not by confirmed cases but by death cases, you’ll get a completely different number.
The study shows people aged 50 years and above are the top in the list of death cases of COVID-19.
70–79 years by far is the age group with most coronavirus deaths (with 30.5% of people). While, 60–69 years (30.2%), ≥80 years (20.3%), 50–59 years (12.7%) age groups are also popular in the same list.
Next, taking into account the confirmed cases and death cases of COVID-19, we calculated the fatality rate of different age groups.
The study calculated the fatality rate according to the age of the people. The fatality rate was found to be higher in older people and lower in younger people.
≥80 years is the age group with most coronavirus fatalities (with 14.8% of people). And 0-9 years is the age group with the least coronavirus fatalities (with 0.0% of people).
Key conclusion: Studying all the graphs suggests that elderly people are probably at the highest health risk from COVID-19.
In this analysis, including both male and female, their confirmed cases, death cases, and fatality rates are studied separately.
The study did not find much difference in confirmed cases of men and women. Males represent the majority of confirmed COVID-19 cases (51.4%), followed by female cases (48.6%).
However, if you look up the graph, not by confirmed cases but by death cases, you’ll get a completely different number.
The study shows males are the top in the list of death cases of COVID-19. 63.8% of people who died from COVID-19 are male, and 36.2% are female.
Next, taking into account the confirmed cases and death cases of COVID-19, according to sex, we calculated the fatality rate of both genders.
The study calculated the fatality rate according to the sex of the people. The fatality rate was found to be higher in males and lower in females.
Key conclusion: Studying all the graphs suggests that males are probably at the highest health risk from COVID-19.
In the analysis, there are 5 different classes of people according to the occupation, in which service industry, farmer/laborer, health worker, retiree, and other/none people are included.
Other/none by far is the most coronavirus-infected occupation (with 45.9% of people). While, Farmer/laborer (22.0%), Retiree (20.6%), Service industry (7.7%), Health worker (3.8%), occupation groups are also fairly infected.
However, if you look up the graph, not by confirmed cases but by death cases, you’ll get a completely different number.
The study shows Retiree are the top in the list of death cases of COVID-19.
Retiree, is the occupation group with most COVID-19 deaths (with 46.1% of people). Other/none (37.5%), Farmer/laborer (13.6%), Service industry (2.2%), and Health worker (0.5%) occupation groups are also popular in the same list.
Next, taking into account the confirmed cases and death cases of COVID-19, we calculated the fatality rate of different occupation groups.
The study calculated the fatality rate according to the occupation of the people. The fatality rate was found to be higher in Retiree.
Retiree by far is the occupation group with most coronavirus fatalities (with 5.1% of people). And Health Worker is the occupation group with the least coronavirus fatalities (with 0.3% of people).
Key conclusion: Studying all the graphs suggests that retirees are probably at the highest health risk from COVID-19.
In this analysis, including Hubei and other provinces, their confirmed cases, death cases, and fatality rates are studied separately.
The study found a considerable difference between confirmed cases of Hubei and other provinces. Hubei represents the majority of confirmed COVID-19 cases (74.7%).
The study shows people related to Hubei are the highest in the list of death cases of COVID-19. 95.7% of people who died from COVID-19 are related to Hubei, and only 4.3% are related to other provinces.
Next, taking into account the confirmed cases and death cases of COVID-19, according to the province, we calculated the fatality rate of Hubei and other provinces.
The study calculated the fatality rate according to the province of the people. The fatality rate was found to be higher in Hubei (2.9%) as compared to other regions (0.4%).
Key conclusion: Studying all the graphs suggests that people related to the Hubei province are probably at the highest health risk from COVID-19.
In the analysis, a total of 37,269 patients are included in 2 different classes. First, those who have contact with Wuhan and the others who have no connection with Wuhan.
The study finds a considerable difference between confirmed cases of people who have contact with Wuhan and the others who have no connection with Wuhan. People with Wuhan-related exposure represent the majority of confirmed COVID-19 cases (85.8%).
The study shows that people who have contact with Wuhan are the highest in the list of death cases of COVID-19. 92.8% of people who died from COVID-19 had contact with Hubei, while only 9.2% did not.
Next, taking into account the confirmed cases and death cases of COVID-19, according to Wuhan-related exposure, we calculated the fatality rates.
The study calculated the fatality rate according to the Wuhan-related exposure of the people. The fatality rate was found to be higher in people who have contact with Wuhan (2.7%) as compared to the people who didn’t (1.2%).
Key conclusion: Studying all the graphs suggests that people who have direct contact with Wuhan are probably at the highest health risk from COVID-19.
In the analysis, there are 6 different classes of people according to pre-existing medical conditions, in which a total of 20,812 people with Hypertension, Diabetes, Cardiovascular disease, Chronic respiratory disease, Cancer (any), and None medical conditions are included.
The study shows people with no medical condition are the highest in the list of confirmed cases of COVID-19.
Hypertension, is the most common pre-existing medical condition (with 12.9% of people). While, Diabetes (5.3%), Cardiovascular disease (4.2%), Chronic respiratory disease (2.5%), and Cancer (0.5%) medical conditions are also fairly common.
However, if you look up the graph, not by confirmed cases but by death cases, you’ll get a completely different number.
The study shows people with Hypertension are the highest in the list of death cases of COVID-19.
Hypertension, is the pre-existing medical condition with most coronavirus deaths (with 31.9% of people). While, Cardiovascular disease (18.3%), Diabetes (15.9%), Chronic respiratory disease (6.3%), and Cancer (1.2%) medical conditions are also popular on the same list.
Next, taking into account the confirmed cases and death cases of COVID-19, we calculated the fatality rate of different medical conditions.
The study calculated the fatality rate according to the medical condition of the people. The fatality rate was found to be higher in people with Cardiovascular disease.
Cardiovascular disease by far is the pre-existing medical condition with most coronavirus fatality rates (with 10.5% of people), followed by Diabetes (7.3%), Chronic respiratory disease (6.3%), Hypertension (6.0%), and Cancer (5.6%).
Key conclusion: Studying all the graphs suggests that people with pre-existing medical conditions such as Cardiovascular disease, Diabetes, Chronic respiratory disease, Hypertension, and Cancer are probably at the highest health risk from COVID-19.
In the analysis, there are 3 different classes of people according to case severity, in which a total of 44,415 people with Mild, Severe, and Critical cases are included.
The study shows people with mild case severity are the top in the list of confirmed cases of COVID-19.
Mild severity has the most COVID-19 cases (81.4% of people) followed by Severe (13.9%), and Critical (4.7%) cases.
However, if you look up the graph, not by confirmed cases but by death cases, you’ll get a completely different number.
The study shows people with mild case severity are the top in the list of confirmed cases of COVID-19.
Mild severity has the most COVID-19 cases (81.4% of people) followed by Severe (13.9%), and Critical (4.7%) cases.
However, if you look up the graph, not by confirmed cases but by death cases, you’ll get a completely different number.
The study calculated fatalities according to the case severity of the people and saw fatal outcomes only in those suffering from critical case severity.
Key conclusion: Studying all the graphs suggests that people with critical case severity are probably at the highest health risk from COVID-19.
This case study has told us a lot about the people who are most vulnerable to SARS-CoV-2. We found this case study interesting because it contains 44,672 confirmed cases of COVID-19, which is much larger in number than any other study.
Here’s the result of the study in short:
Researchers found in the study that this SARS-CoV-2 is highly contagious. It has spread extremely rapidly from a single city to the entire country within only about 30 days.
We learned a lot about coronavirus from this study, and we hope you did too.
We have also discussed the pattern of the coronavirus in detail, here in the Chapter 8: Coronavirus Case Studies.
And now is the time to move to the next chapter.
COVID-19 Fact: Chinese research finds, people with blood type 'A' are at highest risk of coronavirus infection and people with blood type 'O' are at least risk.
Since COVID-19 is still a new disease, doctors are still in its research and are learning new things about it daily.
A study conducted at around 138 patients at Zhongnan Hospital of Wuhan University found that among those infected with the new coronavirus, about 99% of people had a fever. At the same time, more than half experienced fatigue and a dry cough, and about one-third of the people experienced muscle pain and difficulty breathing.
In confirmed cases of COVID-19, symptoms range from mild to severe, starting with a cold and fever. As symptoms are similar to the flu, the disease becomes more challenging to detect. Most common symptoms of COVID-19 may include:
Less common symptoms of COVID-19 may consist of:
The complete list of symptoms is still under analysis.
Prevention is always better than cure. If you have a cough, fever, or you have been in close contact with an infected person or a major outbreak area, get yourself tested for coronavirus infection immediately.
When to consult a doctor: If you are experiencing any of these symptoms, and you have recently been in a major outbreak area, you need to seek medical advice immediately.
According to the Centers for Disease Control and Prevention (CDC), symptoms of COVID-19 can take between 2 and 14 days to appear.
But a study published in the Journal of the American Medical Association (JAMA) found a patient’s incubation period to be 19 days long.
In that study, a 20-year-old woman who previously lived in Wuhan came to Anyang on January 10, after the virus outbreak. Three days later, she went to meet a sick patient (who was not infected with coronavirus) at Anyang District Hospital, along with five members of her family.
On January 17, one of the woman’s family members complained of fever and a sore throat. The following week, the other four relatives also complained of fever and shortness of breath. After that, all those relatives were admitted for investigation at the Fifth People’s Hospital on January 26.
And the investigation revealed that all the family members are infected with coronavirus, and the only woman who came in contact with those people from Wuhan was their 20-year-old relative.
Initially, when the woman was medically tested for coronavirus, no infection was detected. But when the woman was tested again one day later, the infection was detected, but the woman was still not showing any symptoms of COVID-19.
Doctors later revealed that the woman’s incubation period was 19 days long.
Besides, Zhong Nanshan, a Chinese scientist who underwent the discovery of SARS, also conducted a research in which he studied 1,099 laboratory-confirmed patients from 552 hospitals and took a median incubation period of 3 days (range, 0 to 24 days).
COVID-19 Incubation Period: A person can carry and transmit COVID-19 without showing symptoms from 1 to 24 days.
The events of the last few months have made it clear that SARS-CoV-2, first seen in Wuhan, China, is now making tens of millions of people sick worldwide.
As the virus outbreak develops day by day, the information related to it continues to change.
We’ve been following and providing the latest updates on COVID-19 since its outbreak.
Now we are going to tell you how this virus spreads. This information is based on studies conducted until June 7, 2020. But this information can be further developed based on scientific researches happening over time.
COVID-19 spreads from one person to another, similar to other respiratory diseases such as the flu. Here are the possible ways of spreading coronavirus:
Droplet/ particles transmission is the leading cause of virus spread from person to person. When you cough or sneeze, you send droplets into the atmosphere, and others may fall ill when exposed to those infected droplets.
If you cough or sneeze after being infected, your droplet falls on a surface and contaminates it. So later if a person comes in contact with that surface and touches his mouth, nose, or eyes, then he can fall ill.
Poor hand washing is a major cause of fecal-oral virus transmission. If you use the bathroom after being infected and do not take care of hygiene, then everything you come in contact with is contaminated by your feces. So later if a person comes in contact with those things and touches his mouth, nose, or eyes, then he can fall ill.
If you are kissing someone or sharing food in the same plate, if the person is infected with coronavirus, then the virus can easily be transmitted orally from their saliva, even if they aren’t currently experiencing any symptoms.
The virus can be easily spread from person to person through infected person’s urine. There can be many ways of getting an infection this way. For example: If you use the same tap after going to the toilet that the person infected with coronavirus has previously washed his hands, then chances are that you too may be infected with the same virus later.
COVID-19 Fact: Many people mistakenly believe that COVID-19 is airborne, that it spreads through the air, but it is actually spread by droplets and particles of infected individuals.
COVID-19 is still affecting many people worldwide. Most people who become infected recover after experiencing mild illness, but there is always a possibility of infection by them. Therefore, it is important to take care of your health to avoid infection.
There are many things that you can do for your self-protection with the COVID-19. According to the World Health Organization, to keep yourself safe, you need to keep the following things in mind:
Wash your hands with soap with clean running water. After applying soap, rub your hands for at least 20 seconds, then rinse the soap off and finally dry your hands thoroughly with the help of a clean paper towel, air dryer, or cloth hand towel.
If water and soap are not available, then use hand sanitizer. After applying the proper amount of hand sanitizer, rub both hands between your fingers, and under your nails, for at least 25 seconds till it dries quickly after absorbing in hands.
If you need to touch your face, wash your hands first. If you touch your face with dirty hands, you may get an infection from the virus. So, before touching your eyes, nose, and mouth, wash both your hands thoroughly with soap and if the soap is not available, then use hand sanitizer.
If you feel that someone is ill around you, try to stay away from him as much as possible, especially when he is coughing or sneezing. If for some reason you have to go to them, then after the meeting, wash both your hands thoroughly with soap and if the soap is not available then use hand sanitizer.
If you, your children or any of your family becomes ill, do not let that person go to school, office or any public place so that they do not spread the virus infection to others. For a person who is ill, he must stay in the house until he is fully recovered.
Viruses are spread from person to person during coughing and sneezing due to the transmission of droplets from the infected person's mouth and nose. Use tissue or paper towel whenever you cough or sneeze. If you do not have all that available at that time, then sneeze in the elbow.
Clean and disinfect surfaces and objects that are often used, such as doorknobs, bathroom, kitchen, computer, phones, and toys. To clean, mix 3 teaspoons bleach in 1 gallon of water and spray it on the surface and objects, rinse after 3 minutes and let it air dry.
Close contact with sick individuals is the easiest way to infect yourself with the virus. If for some reason you have to do a handshake, hug or kiss with them, then immediately wash both your hands thoroughly with soap and use hand sanitizer if the soap is not available.
A flu shot can help make your life easier. Although seasonal flu shot cannot directly protect you from coronavirus, it can reduce the severity of flu symptoms such as runny nose and cough. Thus, by avoiding the flu, you can also avoid being in a medical environment with coronavirus patients.
When you are sick, you get dehydrated quickly. Due to fever, moisture and electrolytes keep coming out of your body. Due to which your body starts to lack water. So, to restore your moisture levels and to get the bad stuff out of the body, consume sufficient fluids.
When you are sick, it affects your immune system, due to which your body needs more rest. Good sleep helps your body fight infection and disease better. Sleep helps in relaxing your body, making the mind more productive and refreshing your mood.
Scientists believe that coronavirus started in an animal and then spread in humans. Therefore, health officials recommend cooking meat and eggs well before eating. Apart from this, animals that have died due to some disease are not advised to eat.
There’s a fun fact about medical masks that you probably won’t know.
Medical masks are used to prevent infected people from spreading the virus, not to prevent an uninfected person from getting infected.
Now you must be thinking that if this statement is true then why are all people being asked to wear face coverings of clothes in public?
Well, the simple answer to this is that experts are learning more about COVID-19 every day, and because of this, the guidelines on how to prevent the transmission of coronavirus are also changing.
Until recently, experts did not know the extent to which people with COVID-19 could spread the virus before symptoms appeared. There is a large proportion of the population who are asymptomatic carriers of COVID-19 and are propagating the virus. This simply means that no one can really determine the impact of asymptomatic cases until more testing is done. That is, people without symptoms can inadvertently spread the virus to others, so everyone should cover their nose and mouth in public.
If you are one of a healthcare workers—the people who are in closest contact with highly contagious patients, you should use N95 masks or surgical masks.
The N95 is the best face mask as it can filter tiny particles up to 95%, which may possibly contain the virus. However, N95 respirators are not able to provide full protection to children and people with facial hair as it is not designed for them.
According to the FDA, you may use the following types of N95 respirators at the time of public health medical emergencies:
Due to the high demand for N95 respirators, this mask is disappearing from the local market so it is not recommend for general public to wear N95 respirators. Those are critical supplies that must continue to be reserved for health care workers and other medical first responders.
Those of you who do not care for COVID-19 patients should wear homemade cloth masks in public. These types of masks do not prevent healthy people from getting sick, but they can definitely prevent sick people from infecting other people. For example, if you cough or sneeze, a cloth mask can help prevent droplets from circulating in the air. Also, cloth masks can help reduce the spread of COVID-19 by people who have the disease but don’t realize it.
If you wear a mask, then you should know how to use it, how long to use it, and what to do with it after use. According to WHO, masks are put on, used, taken off, and disposed of in this way:
Step 1: Before using a face mask, wash both your hands thoroughly with soap, and if the soap is not available, then use hand sanitizer.
Step 2: Find the metal strip of the face mask, adjust it well above your nose bridge, and stick the elastic strings behind your ears. (While doing this, make sure your mouth, nose, and chin are covered well.)
Step 3: If you feel like moisture in the face mask, remove it from the face by holding it with elastic strings and throw it in a closed dustbin. (While doing this, note that you are not touching the front of the face mask as it may be contaminated.)
Step 4: Repeat Step 1 and Step 2 to wear a new dry face mask. (Never use single-use face masks again.)
Here is the video by WHO which shows the proper technique to put on a face mask in detail:
Cloth face masks should be worn in public settings such as grocery stores and especially in areas of significant community-based transmission, where social distancing is difficult to maintain. Here are some pointers for wearing and taking off a cloth mask:
Step 1: Before using a face mask, wash both your hands thoroughly with soap, and if the soap is not available, then use hand sanitizer.
Step 2: Tie it behind your head or use ear loops and make sure your mouth, nose, and chin are covered well.
Step 3: Remove it from the face by untying it or lifting off the ear loops. (While doing this, note that you are not touching the front of the face mask as it may be contaminated.)
Step 4: Place covering in the washing machine and wash your hands immediately.
Here’s a video by Consumer Reports which shows some simple steps to make sure you are wearing a cloth mask correctly:
The CDC has provided instructions on how to make a mask using just a bandana, old t-shirt, or square cotton cloth. This will help you to make sew and no-sew cloth face coverings easily at home.
Currently, the N95 and surgical face mask are only recommended for infected patients and health professionals dealing with those patients. And cloth face covering is advised for the general public yet.
According to a study, masks are successful in preventing infection only when they are used with frequent hand washing. Therefore, while using masks, it is important to clean your hands from time to time with soap or sanitizer.
Key conclusion: Staying at home is the best option for the safety of yourself and others from COVID-19. If you can’t do that, then making homemade masks is better than nothing.
Coronavirus (COVID-19) testing has been a major point of discussion and concern during the pandemic. But why is there so much focus on testing?
Well, for quick identification of cases, prompt treatment for those and immediate isolation to prevent the spread, the COVID-19 testing is very important. We now have two main kinds of tests available for COVID-19:
We will discuss about both testing methods in detail below:
This is a first type of diagnostic test that tells you if you have a current infection by looking for parts of the virus itself. In this test a long swab is used to collect sample, including physical pieces of coronavirus, from the back of the nose where it meets the throat.
To determine whether a nasopharyngeal sample is positive for the coronavirus, bio-technicians use three different molecular test techniques. Which are:
Viruses such as SARS-CoV-2 contain only RNA, not DNA. Therefore, after a sample collection of a person, the extracted RNA is converted into DNA with the help of reverse transcription.
After that with the help of polymerase chain reaction, the converted DNA sample is amplified to a large enough amount to be examined in order to determine if it matches the genetic code of SARS-CoV-2.
This whole technique is called Reverse transcription polymerase chain reaction (RT-PCR).
Most RT-PCR tests can take anywhere from a few hours to a few days. But the FDA has recently begun giving the Emergency Use Authorization (EUA) for rapid diagnostic PCR tests that can produce results in less than an hour. Examples of authorized rapid diagnostic PCR tests include the following:
In addition, the FDA has also granted Emergency Use Authorization (EUA) for tests that collects saliva instead of using a traditional nasal swab. It is believed that this will reduce the risk for healthcare professionals and will be much more comfortable for patients to collect their own samples more efficiently.
To make testing easier, the FDA has recently authorized at-home coronavirus test kits, with the help of which you can find out if you currently have COVID-19 without leaving home. Examples of authorized at-home coronavirus test kits include the following:
According to the German virologist, Christian Drosten, RT-PCR test performed with the help of throat swabs is reliable only in the first week of illness. Later the virus can disappear in the throat while it grows in the lungs. Samples of people whose illness has been more than a week can be obtained from deep airways with the help of suction catheter or from sputum.
Like PCR, isothermal amplification methods are used to amplify RNA. However these methods are much faster than PCR as they do not involve repeated cycles of heating and cooling the sample.
These tests typically detect amplified virus sequences using fluorescent tags, which are read with specialized machines. Unlike PCR, these methods do not require expensive reagents or instruments, which aids in cost reduction for coronavirus detection.
Here are main differences, if we compare both PCR and Isothermal Amplification based methods of viral RNA detection. [Table adapted from Nguyen et al (2020)]
PCR | Isothermal Amplification Methods |
---|---|
Bulky and cumbersome | Smaller, simpler, portable |
Specialized thermal cyclers required | Only a heat block is required |
4-8 hours until result | 1 hour until result |
Requires skilled technicians | Requires no specific skill |
Requires an additional reverse transcription step | Can be performed directly on RNA |
Unstable reactions prone to inhibitors requiring purification steps | Stable and inhibitors tolerated, and thus purification steps not required |
Detects DNA | Detects DNA and RNA |
Tested on patient samples | Less tested on patient samples |
An antigen test is a new type of diagnostic test designed for rapid detection of the virus that causes COVID-19.
In the antigen test, samples of patients are collected with the help of nasal swab. The antigen test looks for proteins from the surface of the virus present in the collected samples and bind to the strips and gives a visual readout. In the case of coronavirus, these are usually proteins from surface spikes.
One of the main benefits of antigen testing is the speed of testing, which can provide results in minutes. The positive results obtained from antigen tests are highly accurate. But there are more chances of getting negative results wrong, so before deciding the treatment, negative results obtained from antigen test should be confirmed with the help of PCR test.
If we compare the three tests together, we find that PCR tests require much time, energy and trained personnel. And isothermal amplification methods can process only one sample per machine at a time. But antigen test has the ability to do 300 million tests a day at a low cost.
Another approach of test is serology (or antibody) test which identify people who were infected and have already recovered from COVID-19, including those who did not know they were infected.
When a person comes into contact with the virus, his body develops antibodies to fight the invading virus, which can take several days to more than a week. Antibodies are simply proteins made by the immune system in response to an infection and are specific to that particular infection.
In response to infection, immune system produce antibodies including IgM and IgG. According to the FDA, IgM antibodies produced in response to SARS-CoV-2 become detectable in the blood several days after the initial infection. IgG antibodies typically become detectable in the blood 10 to 14 days after initial infection, and peak after 28 days.
Because the body takes time to develop antibodies, serological tests are not useful for quickly identifying whether a patient currently has COVID-19. Rather antibody tests can be used to identify individuals who have had an infection and are recovered.
Some countries are considering issuing immunity passports or risk-free certificates for individuals who have antibodies against COVID-19 so that they can travel again or go to work. But, According to the WHO, it is still unclear that people who have recovered from COVID-19 and have antibodies are protected from a second infection. In such a situation, the use of such certificates may increase the risk of continued transmission. Therefore, even if you are recovered, it is still important to follow the COVID-19 safety guidelines.
Molecular test is used to find out if you currently have COVID-19 infection. But not all require this test.
The first reason for this is that most people have mild illness and can recover at home without medical care and there is no need to get them tested. Apart from this, another reason is that the availability of testing is still limited, so not all can be tested.
We are going to share some recommendations with you on COVID-19 testing. But keep in mind, ultimately, decisions about testing are at the discretion of your state and local health departments.
If you belong to one of these groups, you should get tested for coronavirus:
Clinicians should determine by themselves whether the patient’s signs and symptoms resemble COVID-19 and whether the patient should be tested.
Although the supply of tests is increasing, it can be difficult to find a place to test. So if you have symptoms of COVID-19 and want to get tested, call your healthcare provider first.
If your COVID-19 test is negative, it does not mean that you will not get sick. The test result simply means that you did not have COVID-19 at the time of the test. Therefore, whether the result for your COVID-19 test is positive or negative, you should always take preventive measures for yourself and others.
COVID-19, which started from Wuhan city of China, has now spread its footprint all over the world. According to WHO, around 213 countries around the world are currently vulnerable to coronavirus, and more than 5.9 million people are infected with the coronavirus. So far, 402,283 people have died, and 3,373,551 people have also been treated.
Now the question arises that if no country has any medicine available for the treatment of coronavirus, so how are so many people recovering from all over world?
Well, COVID-19 is currently being treated with drugs that are already approved for other conditions, or have been tested on other viruses.
With the continued growth of COVID-19 cases worldwide, many companies are working on antiviral drugs and other companies are working on vaccines that can be used against the disease.
Currently, three drugs have received the Emergency Use Authority (EUA) from the Food and Drug Administration (FDA), which includes the anti-malarial drugs chloroquine and hydroxychloroquine, anti-viral remdesivir and Fresenius Kabi Propoven 2%.
It would not be right for us to say that the drugs that work against COVID-19 will soon be available in the market. Drug development is actually a very long process in which a drug has to pass from initial discovery to laboratory and animal testing to clinical trials in people.
On average, it takes at least ten years for a new medicine to complete the journey from initial discovery to the marketplace, with clinical trials alone taking six to seven years on average.
Here are the stages of a drug development:
This phase includes the initial phase of research, in which researchers try to discover an investigative drug and
then do initial testing of that drug in the laboratory. This first phase of the process itself takes about three to six years. By the end, the researchers hope to identify a promising drug candidate that can be further studied in lab, animals and then humans.
In this phase laboratory and animal tests are performed to determine whether the drug is safe for human testing. Through these techniques, scientists try to understand how medicine works and what possible side effects the drug can have on humans. Preclinical testing is very important before being allowed to study the candidate drug in humans.
This phase consists of three phases of clinical trials, each with its own specific goals and requirements. The clinical trials process is both expensive and time-consuming, and ends more often in failure than success. Only 12 percent of the candidates who are included in the clinical trials phase get approval. And from beginning to end, the clinical trial phase takes an average of six to seven years. Here are the three phases of clinical trials:
In this stage, drugs become available to patients after the successful completion of discovery, preclinical testing, and clinical trials. But the FDA still requires that companies conduct extensive post-approval research on approved drugs to monitor safety and long-term side effects as long as they stay on the market.
Key conclusion: If we take all the above facts into account, then according to this COVID-19 drug or vaccine will take about 10 years to be made. But in the case of COVID-19, scientists have received a lot of boost from the researches running on SARS and MERS that could accelerate the development of the first COVID-19 vaccine.
Experts also say that coronavirus can become seasonal as a cold and flu. And perhaps a vaccine may not be ready until the current pandemic ends.
As the coronavirus disease 2019 (COVID-19) spreads, efforts are being made to reduce the transmission. While many scientists are working on developing a coronavirus virus vaccine, others are busy testing existing antiviral drugs.
Vaccines are only effective when administered prior to infection, but antiviral drugs can treat people who already have infection. The following existing antiviral drugs are being tested against COVID-19:
Remdesivir is an antiviral drug developed by the biopharmaceutical company Gilead Sciences. In 2014, remdesivir was presented and then rejected as a cure for the ebola virus. But now in 2020, the drug is being seen as an option to treat COVID-19.
In late April, Gilead Sciences announced that one of its tests had been “terminated” due to low enrollment. But few days later, the company announced that in a trial of the antiviral drug remdesivir by the National Institute of Allergy and Infectious Diseases “has met its primary endpoint.”
In its context, the Director of NIAID, Dr. Anthony Fauci reported that people who used the drug remdesivir during the treatment of COVID-19 recovered in 11 days. In contrast, those who did not use remdesivir during treatment recovered within 15 days.
At the same time, another study published in The Lancet found that those who took remdesivir in clinical trial showed no benefit compared to others who took placebo.
Despite of conflicting results, on May 1, the FDA authorized the remdesivir under EUA for emergency use.
Kaletra is a combination product that contains two medications: lopinavir and ritonavir. Kaletra is basically used to treat HIV, but currently its clinical trials are being conducted to see if it also works against SARS-CoV-2.
A study that appeared in the journal Med by Cell Press on May 4 found that the Kaltera drug did not improve outcomes in people with mild or moderate COVID-19.
Also, another study which was published in the New England Journal of Medicine on May 7 found that the drug is not effective for people with severe COVID-19.
However, a study published in The Lancet found that people who were given drug combinations with the two other drugs ribavirin and interferon beta-1b took less time to clear the virus from their bodies.
Favipiravir is an antiviral medication used to treat influenza in Japan and in some countries outside the United States. According to a news report, medical authorities in China have confirmed that a drug (favipiravir) used in Japan to treat influenza is effective in coronavirus patients.
On May 30, Russia’s Ministry of Health also approved the drug favipiravir for COVID-19 treatment, after initial testing showed hospitalized patients who took pills recovered more quickly.
Arbidol is an antiviral medication used to treat influenza in Russia and China. Although some Russian studies have shown it to be effective, it is not approved for use in other countries. It is also not approved by the FDA for the treatment or prevention of influenza.
The drug was tested with kaletra as a treatment for COVID-19, but researchers reported that the two drugs did not improve the condition of hospitalized patients with mild to moderate cases.
In addition to antivirals, scientists are also looking into other ways to fight coronaviruses or treat COVID-19. Some of which are as follows:
Hydroxychloroquine and chloroquine are two drugs that have been used for several decades to treat malaria, recently making headlines as a potential treatment for coronavirus disease (COVID-19).
These drugs received Emergency Use Authorization (EUA) from the FDA in late March but in late April, the FDA issued a warning against the use of both hydroxychloroquine and chloroquine outside medical facilities.
A report by The Lancet found that patients who were being given hydroxychloroquine or chloroquine were dying at higher rates than others who were not being given the same dose.
Subsequently in late May, the World Health Organization announced that it was halting the clinical trials of hydroxychloroquine due to safety concerns.
When a person is infected with a novel coronavirus and is recovered, the person’s immune system produces antibodies to help fight the virus. According to doctors, if antibody-infused blood plasma is given to a newly ill person, in whose body antibodies are not present, it can help to improve those people more quickly.
The FDA has announced a process to conduct tests on an experimental treatment for medical facilities that use the blood plasma of people recovering from COVID-19.
Monoclonal antibodies (mAbs or Moabs) are man-made proteins that are created in the lab and act like human antibodies in the immune system. These drugs stimulate the immune system to attack the virus.
Eli Lilly and AbCellera, which collected 500 unique antibodies from recovered COVID-19 patients, have now begun the first human trials of an antibody drug against COVID-19.
The stem cell therapy is a potential new therapy to battle SARS-CoV-2 that causes COVID-19. COVID-19 affects different people in different ways. Some severe cases of COVID-19 develop acute respiratory distress syndrome (ARDS). The stem cell treatment could potentially benefit people who are suffering from ARDS and require ventilators.
A company Athersys Inc. has begun a phase II/III clinical trial. While the other company Mesoblast is enrolling people with moderate to severe ARDS into a phase II/III clinical trial.
In some people suffering from COVID-19, due to an overreaction of the body’s immune system, its starts releasing large amounts of small proteins called cytokines which causes “cytokine storm”. Scientists believe that it is due to this “cytokine storm” that some people develop ARDS and who then need to be placed on ventilators.
The FDA has approved a device that filters cytokines from patients’ blood.
In addition, to quell the cytokine storm several immunosuppressants including baricitinib– a drug for rheumatoid arthritis, CM4620-IE– a drug for pancreatic cancer, and IL-6 inhibitors are being tested in clinical trials.
Vaccines give you immunity to a disease without you getting sick first. A vaccine basically trains the immune system to recognize a disease-causing germ (in this case SARS-CoV-2) and respond by making special proteins (called antibodies) that help destroy the germ.
That way, if you ever encounters with the same disease germ in the future, your immune system quickly destroys it before it gives you a chance to get sick.
According to the WHO, there are more than 100 projects in the world focused on developing a vaccine for coronavirus. And as of May 11, eight candidate vaccines are being tested in clinical trials in people. Information about some projects is as follows:
Moderna is an American biotech company focused on drug discovery and drug development based exclusively on messenger RNA (mRNA).
In March, the company began testing its mRNA vaccine during phase I clinical trial in 45 healthy volunteers aged 18 to 55. During testing volunteers were getting two shots 28 days apart. In mid-May, the company announced that all 45 participating volunteers had produced antibodies with the help of the vaccine at this initial clinical stage.
In early May, the company received permission from the FDA to begin a Phase II study of its mRNA vaccine.
After Phase II, the company is hoping to begin Phase III clinical trials in July. And if this mRNA vaccine succeeds in the Phase III clinical trial, the FDA has assured the company to fast-track regulatory review of the vaccine.
Inovio Pharmaceuticals is an American biotech company focused on the discovery, and development, of synthetic DNA products for treating cancers and infectious diseases.
The company has developed a potential vaccine for SARS-CoV-2 and has also enrolled 40 healthy volunteers for Phase I clinical trial.
Before the start of COVID-19, the company was working on a DNA vaccine for MERS, another coronavirus-causing disease, and that made it much easier to prepare the vaccine for SARS-CoV-2.
The company is preparing to begin a II/III clinical trial of the vaccine in the summer of this year.
Researchers of University of Queensland are developing a potential vaccine by growing viral proteins in cell cultures. On April 9, the university announced that the UQ team will partner with the Dutch company, Viroclinics Xplore, on the crucial pre-clinical studies.
The University received funding and support from the Coalition for Epidemic Preparedness Innovation (CEPI) to develop a COVID-19 vaccine.
They began preclinical trials in early April and the preclinical analysis revealed that the vaccine candidate raised significant levels of antibodies to neutralize the virus.
The university began clinical trial in late April with more than 500 participants in partnership with a pharmaceutical company called AstraZeneca. The vaccine used in clinical trial uses a modified virus to trigger the immune system.
The company reported in mid-May that the vaccine was effective against COVID-19, while it was given to six monkeys during clinical trial. The company hopes to begin next stages of clinical trials by the middle of this year.
Oxford officials said that the potential vaccine has an 80 percent chance for success in clinical trials and they could deliver 30 million doses by September.
Johnson & Johnson’s Janssen Pharmaceutical Companies are also putting efforts to develop a vaccine candidate through an expanded collaboration with the Biomedical Advanced Research and Development Authority (BARDA).
Apart from this, the drug maker Sanofi Pasteur is also working with BARDA to produce a vaccine that will protect people from new coronavirus.
Another biotech company, Pfizer, says they will have a COVID-19 vaccine ready by the end of October. Pfizer has teamed up with a German pharmaceutical company BioNTech to develop a vaccine. Their initial clinical trial with 200 participants has already given good signals and they have begun human trials in the United States in early May.
China, the world’s most populous country, which previously had the highest number of COVID-19 cases, has now flattened the COVID-19 curve and almost won fight against the SARS-CoV-2.
The current recovery rate of COVID-19 patients in China is around 94.3% and now there are negligible cases.
Despite being the most populous country in the world, how did China curb COVID-19? Is China doing something different from other countries? Well, the answer is YES.
And that’s what we are going to reveal in this chapter.
Traditional Chinese Medicine (TCM) has played an important role in the prevention and control of COVID-19 in China. TCM has been used to reduce fever and increase the body’s immunity on more than 90 percent of China’s COVID-19 patients.
To get a better understanding of TCM’s role in COVID-19 prevention and treatment, we reached Tsao-Lin E. Moy, an acupuncturist and Chinese medicine expert. Tsao-Lin told us that as of February 2 in China, the official use of traditional Chinese medicine was mandated as part of a protocol: prevention, treatment, and recovery with antivirals. She also shared a study with us that tells us how people infected with coronavirus are being treated with the help of TCM in China.
To further improve the treatment of COVID-19 patients, The COVID-19, Prevention, and Control Headquarters asked medical institutions to give priority to Traditional Chinese Medicine along with Western Medicine. They issued a notice stating that all designated medical institutions in Wuhan will ensure that all infected patients take Chinese medicine before midnight (24:00) on February 3, 2020. And indeed, the mandated use of TCM during treatment played an important role in pandemic prevention and control.
During this time, specific TCM wards were established in the designated hospitals, and besides, the TCM team collectively participates in the treatment.
Symptoms before giving TCM to patients were:
Herbal formulations were given to the patients according to the TCM pattern of the person as prescribed by the medical experts on January 30, 2020.
And February 1, 2020, after 2 days of use of TCM, the following differences in symptoms were seen in patients:
Two days after this, on February 3, 2020, eight confirmed patients were discharged from Wuhan Jinyintan Hospital who were either treated with traditional Chinese medicine or either with a combination of traditional Chinese medicine and Western medicine The details of the discharged patients were as follows:
For the complete recovery of the discharged patients, they were given 2 weeks of Chinese herbs doses. The patients were also told how to use the medicine with appropriate exercise and proper diet plan.
The next day, in the report on February 4, 2020, it was found that the use of Traditional Chinese Medicine (TCM) had significantly improved the condition of about 50 people in the ward.
Most people believe that traditional Chinese medicine has helped prevent and treat COVID-19, and they are also eager to learn more about it. But they do not have much information about Traditional Chinese Medicine (TCM). Therefore, we are now going to share with you the exact formulas of TCM used by China in treating 90 percent, COVID-19 patients.
We have details and additional data on Traditional Chinese Medicine (TCM) below.
TCM experts have recommended some formulas, acupuncture and moxibustion protocols for prevention and treatment of COVID-19 which are as follows:

Method and Frequency:
We’d like to thank John Chen for compiling and translating the data that made this study possible. We also want to give a shout out to Michael Norris for digging deep into the data and making it easy to understand and digest.
And for those that are interested, here are links to our study methods.
Keep in mind that you do not have to use the above formulas in place of Western medicines, preferably you have to work towards effective treatment using both Western and Chinese medicine.
Also, patients are advised not to use Chinese medicine for self-treatment and should not consider Chinese medicine as the only treatment. As the condition of all patients may vary, the use of Chinese medicine is not advised without consulting licensed medical practitioners.
While the whole world is fighting a deadly war with coronavirus that causes COVID-19, there are some countries which were previously vulnerable to the virus, are now doing a better job in defeating it.
China, which was at the forefront of the number of coronavirus confirmed cases, is now leading the list of most recovered cases. According to the data, China has recovered about 94.7% of the total infected cases, which is actually very admirable.
As the number of new cases falls, life in China is slowly returning to normal, and workers are gradually getting back to their jobs. Besides, schools, factories, public places, and tourist places have also reopened in China. This means that China’s intentions and objectives regarding COVID-19 are finally proving to be effective.
And this points to the obvious question, which is, how did they do it?
Well, to find out how China did this, we contacted some experts in the medical world and asked them some questions in its context. We interviewed the following people to know more about China’s pro-active steps to control coronavirus:
And talked about the following:
And the answers that we got in our expert’s session are as follows:
Since South Korea is also doing very well in the context of coronavirus, after this, we asked the experts to throw light on the important efforts being made by South Korea.
In response to this Dr. Desai said “In terms of testing, based on the March 20th data, the US lags far behind with only about 135,000 people tested, which works out to 1 out every 2424 people, roughly 15 times less than South Korea – despite both countries having their first confirmed case on January 19th. Unfortunately, the US data doesn’t include testing done by private companies, but as of late March, testing has been well-documented to be woefully inadequate in most parts of the US, requiring days to get a result of being unavailable altogether.”
With this, Dr. Kate Tulenko said, “What we learn from South Korea is that democracies can defeat this virus if that act early and decisively. People might need to give up some rights (such as the right to data privacy) to facilitate contact tracing. But these temporary reductions in rights will lead to a faster return to normal life and a robust economy.”
Finally, Kate Tulenko said that for countries facing new outbreaks, they should focus on social distancing, respiratory and hand hygiene, mass public mask-wearing, mass testing and contract tracing, and central quarantine of all COVID-19 positive patients.
We learned a lot in this chapter about China and South Korea’s efforts against COVID-19, and we hope you did too.
And now is the time to move to the next chapter.
In this chapter, you are going to see two case studies to understand how coronavirus affects your body.
First, you will see a case study of 138 hospitalized patients and learn about their clinical characteristics.
Then you will see what symptoms the first 99 COVID-19 infected patients of Wuhan Jinyintan Hospital displayed.
In December 2019, the novel Coronavirus outbreak began in Wuhan, China. The number of cases was increasing rapidly, but information on clinical characteristics shown by the suffering patients was limited.
Therefore, between January 1 and January 28, 2020, at the Zhongnan Hospital of Wuhan University, a detailed study of the cases of 138 hospitalized patients was done, which was later published in JAMA on February 7, 2020.
Here’s the detailed breakdown of the study:
To understand the pattern of coronavirus infection with this case study, below, we have explained the study with the help of graphs in 3 different parts. Which are as follows:
In this analysis, including both male and female, their ICU and Non-ICU cases are studied separately.
In total, hospitalized patients, males represent the majority with 75 infected cases (54.3%), followed by 63 female cases (45.7%).
After this, to understand the pattern better, we divided the total cases into two parts ICU patients and non-ICU patients.
In the ICU case, 22 males (61.1%) and 14 females (38.9%) had to be transferred to the Intensive Care Unit for further treatment.
In the Non-ICU case, 53 males (52%) and 49 females (48%) were treated in isolation wards.
Key conclusion: Studying all the graphs suggests that men are probably at the highest health risk from coronavirus infection.
In this analysis, we separately studied ICU and non-ICU cases of hospitalized patients admitted to Zhongnan Hospital, according to the comorbidities.
The study revealed that 64 out of 138 patients (46.4%) had one or more pre-existing medical conditions.
In total, hospitalized patients, Hypertension medical condition is common in majority of infected cases 43 (31.2%). Followed by 20 Cardiovascular Disease cases (14.5%), 14 Diabetes cases (10.1%), 10 Malignancy cases (7.2%), 7 Cerebrovascular Disease cases (5.1%), 4 COPD cases (2.9%), 4 Chronic Kidney Disease cases (2.9%), 4 Chronic Liver Disease cases (2.9%) and 2 HIV infection cases (1.4%).
After this, to understand the pattern better, we divided the total cases into two parts ICU patients and non-ICU patients.
In the ICU case, Hypertension, is the most common pre-existing medical condition (with 58.3% of people). Cardiovascular disease (25.0%), Diabetes (22.2%), Cerebrovascular Disease (16.7%), Malignancy (11.1%), COPD (8.3%), and Chronic Kidney Disease (5.6%) medical conditions are also fairly common.
In the Non-ICU case, Hypertension, is the most common pre-existing medical condition (with 21.6% of people). Cardiovascular disease (10.8%), Diabetes (5.9%), Malignancy (5.9%), Chronic Liver Disease (3.9%), Chronic Kidney Disease (2.0%), HIV Infection (2.0%), Cerebrovascular Disease (1.0%), and COPD (1.0%) medical conditions are also fairly common.
Key conclusion: Studying all the graphs suggests that people with medical conditions such as Hypertension, Cardiovascular disease, Diabetes, and Malignancy are probably at the highest health risk from coronavirus infection.
In this analysis, we separately studied ICU and non-ICU cases of hospitalized patients admitted to Zhongnan Hospital, according to the signs and symptoms.
The study revealed early signs and symptoms of all hospitalized patients.
In total hospitalized patients, the most common symptom at onset of illness was fever (98.6%), followed by Fatigue (69.6%), Dry Cough (59.4%), Anorexia (39.9%), Myalgia (34.8%), Dyspnea (31.2%), Expectoration (26.8%), Pharyngalgia (17.4%), Diarrhea (10.1%), Nausea (10.1%), Dizziness (9.4%), Headache (6.5%), Vomiting (3.6%) and Abdominal Pain (2.2%).
After this, to understand the pattern better, we divided the total cases into two parts ICU patients and non-ICU patients.
In the ICU case, the most common symptoms at the onset of illness were Fever (100%), Fatigue (80.6%), Anorexia (66.7%), Dyspnea (63.9%), and Dry Cough (58.3%). And less common symptoms were Myalgia (33.3%), Pharyngalgia (33.3%), Expectoration (22.2%), Dizziness (22.2%), Diarrhea (16.7%), Nausea (11.1%), Headache (8.3%), Vomiting (8.3%), and Abdominal Pain (8.3%).
In the Non-ICU case, the most common symptoms at the onset of illness were Fever (98.0%), Fatigue (65.7%), Dry Cough (59.8%), and Myalgia (35.3%). And less common symptoms were Expectoration (28.4%), Pharyngalgia (11.8%), Diarrhea (7.8%), Headache (5.9%), Dizziness (4.9%), and Vomiting (2.0%).
Key conclusion: Studying all the graphs suggests that fever, Fatigue, dry cough, myalgia, and dyspnea are the most common early signs of SARS-CoV-2 infection.
This case study has told us a lot about the pattern of coronavirus. We found this case study interesting because it focused mainly on the early symptoms of the COVID-19.
Here’s the result of the study in short:
The study also revealed that patients who are mildly ill in the beginning can see major changes in their illness in a week. Patients can see the following changes in their illness:
Doctors also found in these studies of patients that coronavirus infection is accompanied by pneumonia, which has effects in many parts of the body such as the blood clotting system, heart, kidney, liver, and lungs.
We learned a lot about coronavirus from this study, and we hope you did too.
We’d like to again thank JAMA for providing the data that made this research possible.
And now is the time to move to the second case study of coronavirus.
Between January 1 and January 20, 2020, at the Wuhan Jinyintan Hospital, a detailed study of the cases of 99 confirmed cases was done, which was later published in The Lancet on January 30, 2020.
All data of the study was obtained from the patients’ medical records. And if any data was missing or unclear, the researchers clarified the data by direct communication with attending doctors and other health care providers.
We have detailed data and information on the analysis below.
To understand the pattern of coronavirus infection with this case study, below, we have explained the study with the help of graphs in 8 different parts. Which are as follows:
In the analysis, there are 9 different classes of people according to age, in which ≤39 years, 40–49 years, 50–59 years, 60–69 years, and ≥70 years old people are included.
The study shows people aged 40 years and above are the top in the list of confirmed cases of coronavirus infection.
50–59 years is the most coronavirus-infected age group (with 30% of people). 60–69 years (22%), 40–49 years (22%), and ≥70 years (15%) age groups are also fairly infected.
And, the median age of all confirmed cases is 55·5 years.
Key conclusion: Studying all the graphs suggests that elderly people are probably at the highest health risk from coronavirus infection.
In this analysis, including both male and female, their confirmed cases are studied separately.
In total confirmed cases, males represent the majority with 67 infected cases (68%), followed by 32 female cases (32%).
Key conclusion: Studying all the graphs suggests that males are probably at the highest health risk from coronavirus infection.
In the analysis, there are 4 different classes of people according to the occupation, in which agricultural workers, self-employed, employees, and retired people are included.
The study shows self-employed are the tp in the list of confirmed cases of coronavirus infection.
Self-employed, by far, is the occupation group with most coronavirus confirmed cases (with 64% of people). Retired (19%), Employee (15%), and Agriculture worker (2%) occupation groups are also popular in the same list.
Key conclusion: Studying all the graphs suggests that self-employed persons (the people who have to do a lot of social dealing with others) are probably at the highest health risk from coronavirus infection.
In the analysis, there are 6 different classes of people according to pre-existing chronic medical illness. In which people with Cardiovascular & cerebrovascular diseases, Digestive system disease, Endocrine system disease, Malignant tumor, Nervous system disease, and Respiratory system disease, chronic medical illness are included.
The study revealed that 50 out of 99 patients (51%) had one or more pre-existing chronic medical illnesses.
In total confirmed cases, Cardiovascular & cerebrovascular diseases chronic medical illness represent the majority with 40 infected cases (40%). Followed by 13 Endocrine system disease cases (13%), 11 Digestive system disease cases (11%), 1 Malignant case (1%), 1 Nervous system disease case (1%), and 1 Respiratory system disease case (1%).
Key conclusion: Studying all the graphs suggests that people with pre-existing chronic medical conditions such as Cardiovascular & cerebrovascular diseases, Endocrine system disease (diabetes), and Digestive system disease are probably at the highest health risk from coronavirus infection.
In the analysis, there are 3 different classes of people according to clinical outcome. In which people who remained in the hospital, who were discharged, and who died have been included.
The study shows that as of 25 January, 31 (31%) patients had been discharged, and 11 (11%) patients had died, and another 57 (58%) patients were still in the hospital.
Key conclusion: The study of all graphs suggests that coronavirus infection is probably very dangerous, as only 31 percent of the 98 people were discharged.
In this analysis, we studied all confirmed cases admitted in Jinyintan Hospital, according to the signs and symptoms.
The study revealed early signs and symptoms of all confirmed cases.
In total confirmed cases, the most common symptom at onset of illness was fever (83%), followed by cough (82%), shortness of breath (31%), muscle ache (11%), confusion (9%), headache (8%), sore throat (5%), rhinorrhea (4%), chest pain (2%), diarrhoea (2%) and nausea & vomiting (1%).
Key conclusion: Studying all the graphs suggests that fever, cough, shortness of breath, and muscle ache are the most common early signs of coronavirus infection.
In this analysis, we separately studied unilateral pneumonia and bilateral pneumonia cases of confirmed cases admitted in Jinyintan Hospital.
In total confirmed cases, bilateral pneumonia represents the majority with 74 infected cases (75%), followed by 25 unilateral pneumonia cases (25%).
Key conclusion: Studying all the graphs suggests that coronavirus infection causes pneumonia in all patients.
In this analysis, we studied all confirmed cases admitted in Jinyintan Hospital, according to the treatment they received.
In all confirmed cases, the most common treatments of illness were antiviral treatment (76%) and oxygen therapy (76%). Followed by antibiotic treatment (71%), intravenous immunoglobulin therapy (27%), glucocorticoids (19%), mechanical ventilation (17%), antifungal treatment (15%), continuous renal replacement therapy (9%), and extracorporeal membrane oxygenation (3%).
Key conclusion: Studying all the graphs suggests that antiviral treatment, oxygen therapy, and antibiotic treatment are the most common treatments of coronavirus infection till now.
This case study has told us a lot about the pattern of coronavirus. We found this case study interesting because it focused mainly on treatments of the COVID-19.
Here’s the result of the study in short:
Doctors found in the study that in coronavirus infection, all people get pneumonia, which becomes more severe over time, and that made their bodies less capable of fighting the virus.
The study also revealed that the first two deaths occurred of men who had no serious health issues, but they were long-term smokers. Both of them were experiencing severe breathing problems due to coronavirus infection, and eventually, they died due to lung-related complications.
We learned a lot about coronavirus from this study, and we hope you did too.
We’d like to again thank The Lancet for providing the data that made this research possible.
And now is the time to move to the next chapter.
Just as the outbreak of coronavirus has caused a storm of infection in people around the world, there has been a flood of articles about the outbreak on social media. Unfortunately, in this flood of articles, it can be difficult for a common man to separate facts from rumors.
And during a viral outbreak, rumors and misinformation can spread unnecessary fear and panic among people.
So here at Healthroid, we have compiled a long list of the biggest myths about the novel coronavirus and the associated disease COVID-19 to discover the truth and explain how these rumors are misleading.
Let’s dive right in.
Fact: No, no part of this rumor is correct. Scientists around the world continue to look at the origin of the virus until now. Scientists believe that coronaviruses likely originated from bats, just like many other viruses that have recently emerged in humans from wildlife.
Fact: No, according to WHO, UV lamps should not be used to sterilize hands, or other areas of skin as UV radiation can cause skin irritation.
Fact: The truth is that no one is aware of the exact figures of coronavirus cases in China. By the way, if history is seen, China has messed up the data in other coronavirus epidemics in the past. According to The Epoch Times, some leaked documents reveal that the real figures in the Shandong Province of China are up to 52 times higher than the reported figures.
Fact: It is essential to take care of the hygiene of your hands to protect yourself from coronavirus. For this, you need to wash your hands from time to time with alcohol-based hand sanitizer or soap and running water. Yes, after that, you can dry your hands with the hand dryer.
Fact: There is no patent for the recently discovered new coronavirus. The wrong information was given in a Facebook post that a person named Jacob Rothschild owns the patent for Novel Coronavirus, which was later proved wrong by the Fullfact website by fact-checking. Instead, according to The Verge, the coronavirus vaccine will take a long time to come because vaccine development has just started from scratch.
Fact: Thermal scanners cannot detect whether someone is infected with a coronavirus. Thermal scanners work only to measure the rise in the body temperature (fever) of people due to viral infection, whether it is a new coronavirus or any other virus. It takes 2 to 14 days for a person suffering from coronavirus to show symptoms. In such a situation, if a person is infected but is not showing signs of fever, then Thermal scanners also do not provide any information about the coronavirus infection.
Fact: Popular brands Lysol and Clorox have mentioned in their labeling, they have a 99.9% effectiveness against human coronavirus. Yes, products like Lysol and Clorox are effective in disinfecting the previously seen (old) human coronavirus. Still, these products are equally effective against novel (new) coronavirus that has not been proven yet.
Fact: No, according to the WHO, if the virus has already entered your body, then the virus will not die by a spray of alcohol or chlorine. In fact, spraying can damage your mucous membranes (i.e., eyes, mouth). You need to be careful as both alcohol and chlorine are used to disinfect the surfaces with appropriate advice.
Fact: An article published on the website AB-TC claimed that the Chinese government was seeking approval from the country’s Supreme People’s Court to kill 20,000 coronavirus patients to prevent the virus from spreading further. But a US-based fact-checking website Snopes proved the claim to be absolutely false by fact-checking. According to Snopes, this website has a history of spreading misinformation, and this website is full of junk news.
Fact: No, this is not true at all. According to the WHO, people who are receiving a letter or a package from COVID-19 affected areas are not at risk of contracting the new coronavirus. Previous analyzes have shown that coronavirus cannot survive for a long time in objects such as letters or packages.
Fact: Some time ago, a post on social media was viral that in some Asian foods, traces of coronavirus have been found. Those foods include wagyu beef, Yakult, Nongshim Onion Ring snacks, Mi Goreng instant noodles, Lipton peach-flavored iced tea, fortune cookies, two varieties of rice, and Red Bull. In the post, it was being claimed that the statement has been confirmed by the New South Wales Ministry of Health. But later, the New South Wales Ministry of Health rejected this claim in a tweet and said that this post is fake and did not originate from NSW Health or any related institution.
Fact: Currently, there is no evidence that pets such as dogs or cats can be infected with the coronavirus. However, if you come in contact with any animal, you should always wash your hands thoroughly with soap. By taking care of your hygiene, you can protect yourself from bacteria like E.coli and Salmonella, which are easily transferred from animals to humans.
Fact: No, not at all. There is no link between coronavirus and corona beer. You cannot be infected with coronavirus by drinking Corona beer. Unless you share a bottle or glass of beer with a coronavirus infected person.
Fact: No. According to WHO, vaccines against pneumonia do not provide protection against the new coronavirus. The coronavirus is very new and different, so it requires a separate vaccine. Researchers around the world are engaged in the manufacture of the coronavirus vaccine. Although these vaccines are not effective for coronavirus, vaccination against respiratory diseases is highly recommended to protect your health.
Fact: No, in reality, it is not possible. The Center for Disease Control and Prevention (CDC) of Beijing’s Tongzhou district has written a long article in their WeChat account in which they have clarified that farts cannot infect you unless you smell the fart of a pantless patient closely.
Fact: No, according to the WHO, there is no evidence that regular cleaning of the nose with saline has prevented people from coronavirus infection. Regularly cleaning the nose with saline helps people recover quickly from the common cold, but this has not been found in the case of respiratory diseases.
Fact: The symptoms of the new coronavirus are similar to those of the common cold or flu, but the two diseases are very different from each other. People also often compare COVID-19 to the flu, but we have a vaccine for prevention and medications to treat the flu. But there is no such treatment or vaccine available in the case of COVID-19.
Fact: No, this is not true. There is no doubt that garlic is a healthy food that can kill microorganisms or can at least stop their growth. However, there is currently no evidence that people have been saved from the new coronavirus by eating garlic.
Fact: It is true that some other viruses, such as common cold and flu, spread less in the summer season than in the winter season. But we cannot exactly compare this new coronavirus to other viruses because much more is yet to be known about its communication, severity, and investigation. So, unfortunately, it is difficult to know whether the hot weather will slow down the new coronavirus.
COVID-19 Update: Coronavirus can survive in both hot and humid climates: WHO
Fact: No, sesame oil does not kill the new coronavirus. According to the WHO, some chemical disinfectants such as bleach/chlorine-based disinfectants, either solvents, 75% ethanol, peracetic acid, and chloroform, are effective in killing coronavirus in surfaces. But those chemical disinfectants should not be used in the skin as it can be dangerous.
Fact: It is not correct to say that chicken soup will stop the coronavirus; instead, it is right to say that chicken soup helps in fixing the mood of a sick person. Studies have shown that the ingredients of chicken soup, such as chicken, carrots, and garlic, boost the body’s immune system. Additionally, chicken contains high amounts of the amino acid tryptophan, which helps to produce a neurotransmitter called serotonin, which makes the sick person feel comfortable.
Fact: No. According to the WHO, people of all ages can be infected with the new coronavirus. However, older people and people with pre-existing medical conditions (such as asthma, diabetes, heart disease) have a higher chance of getting infected with the new coronavirus than others. Therefore, all people, whether they are children, or adults, or older people, all need to take the same precaution to protect themselves.
Fact: No, this statement is false. A few weeks ago, Kimchi, a Korean staple dish made from fermented cabbage, chili peppers, and garlic, was famous all over the internet. People were claiming that eating Kimchi can prevent a coronavirus infection. But later, South Korea’s Health Ministry disproved this claim and said, “Kimchi provides no protection against the new type of coronavirus. The best way to prevent the novel coronavirus is to wash hands frequently.”.
Fact: No, antibiotics only act against bacteria and not viruses. And since COVID-19 is a disease caused by a coronavirus, in this case, antibiotics cannot be used in any way to prevent or treat it. However, if you are hospitalized for COVID-19, and you also have a bacterial infection, then, in this case, you may need antibiotics.
Fact: No. Cow dung and urine are only excreta, which have nothing to do with coronavirus. No scientific study has been revealed so far that talks about the antiseptic properties of cow dung and urine. Therefore, it is complicated to say whether cow dung and urine can protect us from infection of any virus-like coronavirus.
Fact: No. There is no scientific evidence that drinking bleach, MMS, or other sodium chlorite products will help prevent disease. Instead, the FDA has stated in one of its posts that the use of sodium chlorite products is dangerous, so it should be stopped immediately.
Want to find out more about the Coronavirus Disease 2019 (COVID-19)?
Got questions? We’ve got answers!
Below you’ll find answers to the questions we get asked the most about the novel coronavirus.
Novel Coronavirus (SARS-CoV-2) is a new virus in the coronavirus family that has never been seen before.
Yes, there are seven types of coronavirus.
The four coronaviruses that are common and not too dangerous are:
‣ 229E (alpha coronavirus)
‣ NL63 (alpha coronavirus)
‣ OC43 (beta coronavirus)
‣ HKU1 (beta coronavirus)
Other three coronaviruses that can cause great harm to humans are:
‣ SARS-CoV (beta coronavirus)
‣ MERS-CoV (beta coronavirus)
‣ COVID-19 (previously known as 2019-nCoV)
COVID-19 is the official name of the disease caused by a novel coronavirus (SARS-CoV-2). In COVID-19, ‘CO’ stands for ‘corona,’ ‘VI’ for ‘virus,’ ‘D’ for disease, and ‘19’ for the year 2019.
No. ‘COVID-19’ and ‘2019-nCoV’ are the different names of the same disease. Formerly, the disease caused by novel coronavirus was referred to as ‘2019-nCoV’, but on February 11, 2020, the World Health Organization renamed the illness to ‘COVID-19’.
Wuhan, the capital of Central China’s Hubei province.
Researchers believe the COVID-19 infection spread to humans from animals. And animals suspected of spreading the virus are pangolins, bats, and snakes.
Most common symptoms of COVID-19 may include:
‣ Fever
‣ Fatigue
‣ Dry cough
‣ Shortness of breath
‣ Myalgia
‣ Pneumonia
Less common symptoms of COVID-19 may consist of:
‣ Runny Nose
‣ Nausea
‣ Vomiting
‣ Dizziness
‣ Diarrhea
‣ Sore throat
‣ Headache
The complete list of symptoms is still under analysis.
The coronavirus spreads from person-to-person.
‣ First, when a sick person releases small droplets of saliva or mucus from his mouth or nose while coughing or sneezing, and some other people near him come in direct contact with those droplets.
‣ Second, when small droplets of saliva or mucus released by a sick person land on objects and surfaces, which is later touched by someone.
Studies so far have shown that coronavirus spreads only through exposure to respiratory droplets.
Many people who are infected with coronavirus initially show no symptoms or very mild symptoms; by looking at them, it may seem that they are completely healthy. So it is possible to get coronavirus infection from asymptomatic people.
Coronavirus is generally believed to spread from person-to-person via respiratory droplets. There is currently no evidence to support the food-related transmission of coronavirus. However, it is important to always wash your hands with soap and water before cooking or eating.
You can reduce the chances of getting infected or spreading coronavirus by taking a few simple precautions. Properly washing your hands is one of the most important things you can do to help prevent and control the spread of coronavirus. Visit the COVID-19 Protection Section to learn more about how to protect yourself from COVID-19.
It depends on where and with whom you are. If you are in an area or with a person where the virus outbreak has just started gaining momentum, there is a higher risk of infection from coronavirus.
Researchers are still learning about how coronavirus affects people. However, some research has shown that older people and individuals with pre-existing medical conditions develop more severe illnesses than others.
You should get tested of coronavirus, if:
‣ you are feeling sick with fever, cough, or difficulty breathing.
‣ have been in close contact with a coronavirus infected person.
‣ you live in or have recently traveled from an area with the ongoing spread of coronavirus.
No, antibiotics only act against bacteria and not viruses. And since COVID-19 is a disease caused by a coronavirus, in this case, antibiotics cannot be used in any way to prevent or treat it.
No vaccine or medicine has been developed yet for the prevention and treatment of coronavirus.
There is a large proportion of the population who are asymptomatic carriers of COVID-19 and are propagating the virus. So everyone should cover their nose and mouth in public.
The incubation period means the time between a person being infected with the virus and showing symptoms after the infection. According to most studies, the incubation period of coronavirus is from 1 day to 24 days.
No, there is no evidence so far that a pet has been infected with coronavirus or a pet has spread coronavirus.
It is not sure how long the coronavirus can survive on a surface. But studies suggest that this novel coronavirus, like any other coronavirus, can remain on a surface for a few hours to a few days.
Yes, firstly, there is very little chance of an infected person to contaminate a package. Subsequently, after transferring the package in different conditions and temperatures, the chances of infecting a person are nearly zero.
The World Health Organization (WHO), Johns Hopkins University, and other institutions have created useful dashboards to track COVID-19 outbreaks worldwide, where you can easily access real-time statistics on active cases, deaths, and recoveries of Coronavirus Disease 2019.
Apart from this, we have also published a data tracker on Healthroid with detailed and accurate information about COVID-19 cases worldwide.
Here is an interactive web-based world map to track COVID-19 statistics in real time.
If you are on the desktop, move the mouse cursor over the location to see the data. Apart from this, if you are on mobile or tablet, touch above the location to see the figures.
To identify new cases, we monitor various twitter feeds, online news services, and direct communication sent through the dashboard.
Here are the figures that shows the current country-wise confirmed cases, death cases and recovered cases of COVID-19. All countries are listed in the table from top to bottom based on the number of confirmed cases, just scroll the table to see the cases of other countries.
The table given below shows the increase in the number of confirmed cases, death cases and recovered cases and the rate of increase in the last 24 hours. All countries are listed in the table from top to bottom based on the number of confirmed cases. If the name of your country is not in the table, search for the required name with the help of search bar.
Country | Cases | 24h | Deaths | 24h | Recovered | % | Active | Tests |

Here is a dashboard published and hosted by Johns Hopkins University that shows the number and location of confirmed COVID-19 cases, deaths, and recoveries in all affected countries.
In this dashboard, you can filter COVID-19 confirmed cases, death cases, and recovered cases by country/region.
If you are unable to see this dashboard in mobile phones, then a mobile-friendly version of the embedded panel is available here.
The World Health Organization (WHO) has also published a dashboard similar to that of Johns Hopkins. This real-time dashboard also provides information about confirmed cases and death cases of COVID-19 worldwide.
If you want to see information about COVID-19 cases of a specific country/region, you can filter the data from the right top corner.
The University of Oxford, Healthmap, Harvard Medical School, Boston Children’s Hospital, Northeastern University, Oxford Martin School, together with several other contributors, have prepared a data map of COVID-19 outbreak cases worldwide by taking help from government reports and news media.
The specialty of this data map is that by clicking on its map, you can easily find the data of confirmed cases of a particular location.
Also, if you click the “Animate Spread” button on the map, you can see in the animation how the coronavirus is making its mark around the world.
COVID-19 Fact: This is the first time in history when a global virus outbreak data has been opened in this way to the world.
The coronavirus outbreak has now spread to six continents out of the total seven continents of the world, except Antartica.
It is known that coronavirus is increasing its speed. Apart from China, coronavirus has spread its foot in many big countries like India, Italy, Iran, South Korea, Spain, Germany, France, and USA.
The World Health Organization (WHO) issued a global public health emergency warning on January 30, 2020, for the sixth time in its history regarding coronavirus outbreak. Here is a quick look at the other five outbreaks, in which the warnings of the global public health emergency were issued in the past.
The WHO defines the global public health emergency as “an extraordinary event which is determined to constitute a public health risk to other states through the international spread of disease and to potentially require a coordinated international response”.
The WHO declares a disease as global public health emergency only when such a situation arises which is “serious, sudden, unusual or unexpected”.
And this is actually happening. In fact, an immediate international action is required, in the case of the novel coronavirus.
The WHO, by issuing a global public health emergency warning, had expressed concern about a situation, it is now in front of all of us.
Now, World Health Organization has declared the coronavirus outbreak a global pandemic. According to WHO, the reason for declaring coronavirus as pandemic is its “uncontrolled spread”.
“A pandemic is an epidemic outbreak that occurs on at least two continents at the same time.”
So, what’s an epidemic?
Well, both pandemic and epidemic terms are used interchangeably during the outbreak of a disease according to its spread.
If the spread of a disease extends to only one continent, it is called epidemic. If at the same time, if the disease spreads in more than one continent, then epidemic itself is called pandemic.
In short: Epidemic is an outbreak that occurs in only one continent and Pandemic is an outbreak that occurs in more than one continent.
Some example of Epidemics are:
Some example of Pandemics are:
As you can see, diseases are divided into epidemic or pandemic categories not based on the number of deaths but according to the spread of the diseases. So you do not need to panic unnecessarily by hearing the word pandemic.
Yes, that’s true that a coronavirus outbreak has caused pandemic first time in history. And virus is proving itself to be much more contagious than other coronaviruses like SARS and MERS.
But, so far, looking at the virus outbreak, it seems that the goal of the virus is not mass killing, but mass replication. This does not mean that you do not have to take COVID-19 seriously.
Keep in mind coronavirus is serious and you also need to be serious to prevent it.
Do you know that a coronavirus infected person can infect at least two more people?
Yes, you heard that right.
Now imagine if 100 people have coronavirus infection, but they are not showing symptoms, and in the absence of information, they are wandering around you openly.
And if each one of those 100 people infects two others, then the total number of infected people will immediately rise to 300. Whose calculation is as follows:
If 100 infected people can do so many infections, then what if the number is 1000 or 10,000?
Isn’t that frightening? Yes, it is.
You may be wondering what you can do in such a situation? Neither you are a doctor nor a medical professional.
Well, the best thing you can do now is to stay informed and keep others informed as well. And that’s what the #AwarenessIsCure Challenge is all about.
The motive of the #AwarenessIsCure Challenge is to promote awareness of the COVID-19. Here’s the simple one-step process:
Rules for this challenge are straightforward:
First, within 24 hours of being challenged, participants have to share this guide with the #AwarenessIsCure hashtag on their social media profiles.
Then, the participant can nominate a minimum of three other people to participate in the challenge.
Everyone has the ability to contribute to protect themselves and to protect others. Let us together spread this guide to people at a rate higher than the spread rate of coronavirus. Let’s share this guide with other people so that those who are still unaware of the coronavirus also know the right way to deal with it.
Let’s unite to fight the coronavirus.
And finally we would just like to say that awareness is the cure at the moment. So the more people you can make aware, the more you can slow down the spread of coronavirus.
You can use the below buttons to share the guide.
