Areas with Risk of Yellow Fever Virus Transmission in Africa1

Map: Africa showing areas at risk for Yellow Fever Transmision in Angola, Tanzania, Democratic Republic of the Congo, Republic of the Congo, Gabon, Equatorial Guinea, Burundi, Rwanda, Uganda, Kenya, Somalia, Ethiopia, Central African Republic, Cameroon, Nigeria, Benin, Ghana, Cote d'Ivoire, Liberia, Sierra Leone, Guinea, Buinea-Bissau, The Gambia, Senegai, Burkina Faso, Togo, and parts of Mauritania, Mali, Niger, Chad, and Sudan.

1 Map is current as of August 2018. This map is an updated version of the 2010 map created by the Informal WHO Working Group on the Geographic Risk of Yellow Fever.

2 Yellow fever (YF) vaccination is generally not recommended in areas where there is low potential for YF virus exposure. However, vaccination might be considered for a small subset of travelers to these areas who are at increased risk for exposure to YF virus because of prolonged travel, heavy exposure to mosquitoes, or inability to avoid mosquito bites. Consideration for vaccination of any traveler must take into account the traveler’s risk of being infected with YF virus, country entry requirements, and individual risk factors for serious vaccine-associated adverse events (e.g., age, immune status)

See the traveler’s health website for any recent updates on risk areas.

3Countries/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”.

4These countries are not holoendemic (only a portion of the country has risk of yellow fever transmission).

Countries with low potential for exposure to yellow fever virus (YFV)5
  • Eritrea6
  • Rwanda
  • São Tomé6
  • Somalia6
  • Tanzania
  • Zambia6

5Countries listed in this table are not contained on the official WHO list of countries with risk of YFV transmission. Therefore, proof of yellow fever vaccination should not be required if traveling from one of these countries to another country with a vaccination entry requirement (unless that country requires proof of yellow fever vaccination from all arriving travelers).

6 These countries are classified as “low potential for exposure to YFV” in only some areas; the remaining areas of these countries are classified as having no risk of exposure to YFV.
