Areas with Risk of Yellow Fever Virus Transmission in South America

Map is from the following publication: Jentes ES. Poumerol G, Gershman MD, et al. The revised global yellow fever risk map and recommendations for vaccination, 2010: consensus of the Informal WHO Working Group on Geographic Risk for Yellow Fever. Lancet Infect Dis. 2011;11:622-32.

1Countries/areas where “a risk of yellow fever transmission is present,” as defined by the World Health Organization, are countries or areas where “yellow fever has been reported currently or in the past, plus vectors and animal reservoirs currently exist”.

2These countries are not holoendemic (only a portion of the country has risk of yellow fever transmission).
