Yellow fever is an acute viral disease. The virus, a 40 to 50 nm enveloped RNA virus of the family of Flaviviridae is transmitted by the bite of mosquitoes (the yellow fever mosquito, Aedes aegypti, and other species). Yellow fever is an important cause of hemorrhagic illness in tropical and subtropical areas of Africa and South America despite existence of an effective vaccine.
