An effective cholera vaccination is not available. Recommended prophylactics for malaria are two tablets of paludrine daily and two tablets of nivaquine weekly, a regime which should be started one week before arriving and continued for three or four weeks after leaving. You should also avoid being bitten whenever possible by wearing long sleeve shirts, using repellents, staying inside after dark and by using mosquito nets. Mosquito nets are NOT available locally, but mosquito screening for windows is readily available. AIDS is a growing problem and it is thought that all prostitutes are HIV positive.
Condoms are widely available.
If you are travelling outside a town please carry an emergency AIDS kit with you. There is rabies and bilharzia but the other most likely hazard comes from the tumbu or putzi fly. It lays eggs in damp clothes, towels or swimwear, especially if left outside to dry. These eggs hatch out under human skin causing painful and unpleasant swellings. Ironing everything should kill the eggs.
