Travellers coming from infected countries require a yellow
fever vaccination certificate. Precautions against Hepatitis A, and
rabies are also recommended. Other risks include typhoid, polio and
bilharzia; a high prevalence of AIDS/HIV exists. There is a risk of
malaria all year in most of the country, particularly in the
Zambezi Valley, Victoria Falls, Hwange National Park and in the
Eastern Highlands; the risk is very small in Harare and Bulawayo.
Mosquitoes are chloroquine resistant. Precautions against mosquito
bites should be taken to avoid any number of mosquito-borne
diseases. Cholera outbreaks occur usually during the rainy season
when flooding and contamination of water sources takes place.
Rapidly declining health standards are also responsible for the
world's lowest life expectancy according to WHO, and a breakdown in
the water distribution system, especially in Harare. Visitors are
advised to take food and hygiene precautions. The standard of tap
water in urban areas is considered low, and bottled water is
available. The current economic instability has led to shortages of
medication in public hospitals, and many staff are on strike; it is
advisable to bring a supply of personal medication. Medical
insurance is essential. Private clinics expect cash payment and
medical costs can be high.
