Transmission of Yellow Fever
How Is Yellow Fever Transmitted?
Yellow fever is a viral disease that is transmitted by Aedes spp. mosquitoes.
Generally, yellow fever is transmitted only in certain areas of Africa and South America. In South America (especially Brazil), infections occur sporadically, and usually among forestry and agricultural workers. In Africa, infections occur primarily in the tropical areas of western and central Africa, but also in urban locations as well as jungle regions.
