What areas are high risk for contracting yellow fever?

Reader Stories

Yellow fever is endemic in tropical and subtropical regions of Africa and South America, though an estimated 90% of the cases reported occur in Africa. Most of the cases on the African continent occur in unvaccinated individuals who inhabit the sub-Saharan region. Though no cases of yellow fever outbreaks have ever been reported in Asia, this area remains a theoretical risk because the mosquitoes responsible for transmission, as well as the susceptible primates, are found there.
