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.

Several factors determine an individual's risk of acquiring yellow fever during travel, including the area of travel, season, immunization status, duration of exposure, activities during travel, and the local rate of virus transmission.
