Yellow fever is an illness carried by mosquitoes, usually in tropical or subtropical countries. People with yellow fever often experience a headache, fever, chills, and nausea, and most recover within a week of symptoms. However, some patients experience a recurrence of symptoms, in addition to liver and kidney problems. When the liver starts to malfunction, the skin begins to turn yellow because of jaundice, hence the term “yellow fever.”
There is currently no treatment of yellow fever other than addressing the symptoms. The best treatment is prevention through a vaccine.
