Yellow Fever Transmission
The yellow fever virus is in the genus Flavivirus, in the family Flaviviridae. Yellow fever is transmitted in "jungle cycles" between non-human primates and mosquitoes in jungles of South America and Africa, and in savannahs of Africa. Humans can acquire yellow fever from jungle mosquitoes. Peridomestic transmission from humans to mosquitoes and thence to other humans in "urban cycles" can cause yellow fever epidemics in cities and towns of tropical America and Africa. Currently, yellow fever transmission occurs almost exclusively in areas of sub-Saharan Africa and South America.
