Zimbabwe falls within a malarial high risk zone, and it is imperative that you take necessary precautions. Take malarial prophylactics before, during and after your Zimbabwe safari.
No immunizations are required, however a tetanus immunization is recommended. If you are traveling from a cholera or yellow fever infected area, you must be in possession of an International Certificate of Vaccination.
Avoid swimming in rivers and dams which may be infected with bilharzia (and are often home to crocodiles and hippos as well!).
Medical facilities in Harare and Bulawayo are good, but pharmacies and mecial care are limited elsewhere. We suggest that you bring any necessary medication with you, and travel with a small first aid kit. Should you need medical attention during your time in Zimbabwe, doctors and hospitals usually require immediate cash payment (some take credit cards). We recommend that all travelers to Zimbabwe have a comprehensive travel insurance policy which covers you for repatriation to your home country.
Tap water is safe to drink.
