Summary
The changing epidemiology of yellow fever and continued reports of rare but serious adverse events associated with yellow fever vaccine have drawn attention to the need to revisit criteria for the designation of areas with risk for yellow fever virus activity, and to revise the vaccine recommendations for international travel. WHO convened a working group of international experts to review factors important for the transmission of yellow fever virus and country-specific yellow fever information, to establish criteria for additions to or removal from the list of countries with risk for yellow fever virus transmission, to update yellow fever risk maps, and to revise the recommendations for vaccination for international travel. This report details the recommendations made by the working group about criteria for the designation of risk and specific changes to the classification of areas with risk for transmission of yellow fever virus.

WHO revises yellow fever guidelines for East Africa to exclude Tanzania

The World Health Organisation (WHO) has revised its recommendations for the Yellow Fever vaccination in Africa.

The new 2011 WHO report indicates that in East Africa, only Tanzania and part of Kenya from Nairobi to the coast are classified as low risk zones to the disease. But the whole of Uganda, Rwanda and Burundi remain high-risk areas.

Previously, the entire east and southern Africa were classified as Yellow Fever endemic and WHO recommended vaccination for all travellers aged nine months or older.

According to the new re-classification, travellers to and from these low risk areas will not require to produce proof of vaccination unless travellers? itineraries indicate potentially increased risk of exposure.

However, according to the international health regulations, countries with vulnerable populations and susceptible vector species can define their own yellow fever vaccine entry requirements.

In Kenya, only North Eastern Province, Kilifi, Kwale, Lamu, Malindi and Tana River in Coast Province have been classified as areas with low potential for exposure.

The new recommendations came up after recognition by travel medicine experts at WHO and Centre for Disease Control and Prevention (CDC) in 2008 of the need to harmonise both the classifications of geographical risk for yellow fever and vaccine recommendations.

WHO then convened a consultation group on yellow fever and international travel to discuss factors important for transmission of the virus, to establish criteria for the addition or removal of countries and geographical regions and to revise the yellow fever risk map and recommendations for vaccination...
