Health in South Africa
Without going into the stats, we can tell you that AIDS is a big problem in South Africa and so extra precaution needs to be taken when conducting intimate relations with a local or fellow traveller.
Malaria is found only in the Lowveld of Mpumalanga and Limpopo and on the Maputaland coast of KwaZulu-Natal but is not much of a risk in the winter months. Although the incidence of malaria is rare, it would be best to take adequate precautions if you choose to visit these areas.
