Yellow fever is a virus that is transmitted to people via the bite of an Aedes mosquito. The virus is typically found in tropical and subtropical areas in South America and Africa. Yellow fever kills 60,000 people a year. Individuals who become infected with yellow fever can experience illness that ranges in severity from a self-limited febrile illness to severe liver disease with bleeding. Symptoms typically take around 3-6 days to develop and include fever, chills, headache and muscle aches.
