The World Health Organisation (WHO) has revised the Yellow Fever vaccination recommendations for Africa.
The Centre for Disease Control (CDC) updated on the 6th May 2011 explains that Zambia and Tanzania fall into Table 12.2b which are countries with only areas of low potential exposure to the yellow fever virus (YFV)1.
All of the countries in this table are labelled as 1:
“1 Countries listed in this table are not contained on the official WHO list of countries with risk of YFV transmission (Table 2-12a). Therefore, proof of yellow fever vaccination should not be required for people travelling 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 travellers)”
Zambia is also numbered as 2 in this table:
“2 These countries are classified as having “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.”
Tanzania is labelled as 3:
“3 The entire area of these countries is classified as having “low potential for exposure to YFV.”
Following this revision by the WHO the South African Department of Health has revised the entry requirements for South Africa and now requires all arriving travellers from these countries to have proof of yellow fever vaccination.
Therefore if you are travelling to Zambia and South Africa, even if you are only in transit, in order to gain entry into South Africa you will need to show your internationally recognised Yellow Fever Vaccination Certificate at immigration. If you are unvaccinated they are within their rights to deny you entry into the country or in some circumstances, place you in quarantine
