Yellow fever vaccinations are required and private health insurance is strongly advocated. Malaria, typhoid fever, tetanus, cholera, tuberculosis, and similar communicable diseases pose the most serious health risks in Tanzania. Visitors are advised to consult their GP for advice on prophylactic treatment and vaccinations against these diseases. HIV and AIDS are endemic on the African continent and every possible precaution must be taken against them. Tanzania is a tropical country; all cuts and scrapes must be instantly cleaned and covered to prevent infections. Water is not always safe for drinking except after purification. Only boiled or bottled water is risk free.
Health care is fairly adequate with over 2000 hospitals and clinics in the country but most facilities are located in the major cities. Treatment is expensive, so medical insurance is important.
Travelling in Tanzania is usually trouble free but the incidence of petty crimes, theft and muggings is rising. Travellers should exercise caution on beaches, in isolated areas, in public transport and in stationary vehicles especially after dark. The Tanzanian borders with Rwanda and Burundi has been the site of minor military clashes, and refugees constantly cross into Tanzania often resulting in incidents of criminal and violent nature. These areas are best avoided. The islands of Zanzibar are currently simmering state of unrest with frequent clashes between security forces and demonstrators who oppose the union and want more autonomy for the islands. While tourists are not the targets of such unrest, it is advisable to update safety information with your embassy in Dar es Salaam.
