Yellow fever is a rare viral disease caused by the bite of a mosquito. Many countries still require visitors to be vaccinated for it before entering.
Yellow fever is found mainly in certain areas of Africa and in South America. In South America, infections happen only every now and then. They are usually among forestry and agricultural workers. In Africa, infections happen mostly in the tropical areas of western and central Africa. But they also happen in cities and jungle areas.
Each person may have slightly different symptoms. The following are the most common symptoms:
Symptoms usually happen within 3 to 6 days after you are exposed to the virus. Symptoms may look like other health problems. Always see your healthcare provider for a diagnosis.
Your healthcare provider will figure out the best treatment for you based on:
Treatment is aimed at controlling your symptoms. This includes rest and plenty of fluids. You may also need to take medicine to help relieve fever and aching. You should not take aspirin or nonsteroidal anti-inflammatory medicines (like ibuprofen or naproxen). These may raise the risk of bleeding.
You should protect yourself from mosquitoes during the illness. This may mean staying indoors or under a mosquito net. This will help keep you from passing the disease on to other people.
