Yellow fever is a severe viral illness that can be fatal. It’s most commonly spread through the bite of an infected mosquito, but it can also be contracted through close contact with someone who has the disease. Symptoms of yellow fever include high fever, muscle pain, and a rash. The virus can be fatal in up to 90% of cases. Prevention includes using insect repellent and wearing long-sleeved shirts and pants when outdoors.
The disease is most commonly found in tropical and subtropical regions of the world, but it can also be found in temperate regions. It usually lasts about a week, but can last up to 14 days in severe cases. There is no specific cure for yellow fever, but treatment includes rest, fluids, and antibiotics.
Yellow fever is caused by a virus called Aedes aegypti mosquito. The mosquito is the primary vector for the virus, which lives in human blood. The virus is spread to people through mosquito bites. The infection can also be spread through close contact with an infected person’s blood or body fluids.
There are three types of yellow fever viruses: Yamagata, Sudan, and Japanese. Each type of virus can cause different types of yellow fever. The most common type of yellow fever, caused by the Yamagata virus, is a severe illness that can lead to death in 50-80% of cases. Other types of yellow fever can be milder and cause only mild symptoms such as headache, body aches, and vomiting. However, all three types of viruses can still be deadly if not treated correctly.
The most common symptoms of yellow fever are fever, chills, headache, muscle aches and fatigue. In some cases, people may also experience nausea, vomiting and diarrhoea. A rash may also develop on the chest, back or throat. If left untreated, yellow fever can lead to serious health problems including liver failure, brain damage and death.
The yellow fever vaccine is the most effective way to prevent yellow fever. The vaccine works by protecting people from the disease before they get infected. It is important to get vaccinated as soon as possible after your travel has been planned, especially if you are travelling to a high-risk area. If you do get sick with yellow fever, the antiviral medication oseltamivir can help fight the virus and shorten your illness. There are also medications that can help treat the symptoms of yellow fever such as fever, headache, chills, and a rash.
