Africa Risk Areas for Yellow Fever Virus Transmission

Dec 13, 2012 | Yellow fever | 0 comments

These are areas where the virus is present in monkeys and is a potential risk to humans as defined by the World Health Organisation. Some of these countries demand a yellow fever certificate from travellers as a condition of entry to their country. Many of these, and other countries, will ask you for a certificate if you are entering from an infected country.

Your travel agent should inform you if you need a certificate when you are booking your holiday or flight. You can double check if in doubt with your local yellow fever vaccination centre.

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

  • Eritrea2

1 Countries 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).

2 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.
