Travellers are advised to take medical advice at least three
weeks before leaving for Tanzania. Most visitors will need
vaccinations for Hepatitis A, typhoid, yellow fever and polio.
Those arriving from an infected country are required to hold a
yellow fever vaccination certificate. There is a risk of malaria
all year and outbreaks of Rift Valley Fever occur; travellers
should take precautions to avoid mosquito bites. Food prepared by
unlicensed vendors should also be avoided, as meat and milk
products from infected animals may not have been cooked thoroughly.
Sleeping sickness is a risk in the game parks, including the
Serengeti, and visitors should take precautions against bites by
tsetse flies. There is a high prevalence of HIV/Aids. Cholera
outbreaks are common throughout the country and visitors are
advised to drink bottled or sterilised water only. Travellers
climbing Mt. Kilimanjaro are at risk for altitude sickness. Medical
services are available in Dar-es-Salaam and other main towns, but
facilities and supplies are limited; visitors with particular
requirements should take their own medicines. Comprehensive medical
insurance is advised.
