What is the current situation?
Health officials in South Africa have reported limited cases of locally transmitted malaria in Gauteng Province, where Johannesburg and Pretoria are located. Local transmission means that mosquitoes in the area may have been infected with malaria and are spreading it to people. Malaria is not usually found in Gauteng Province, but rare outbreaks have been reported in the past.
Public health authorities are responding to this outbreak by enhancing malaria surveillance, making sure that patients are diagnosed and treated promptly, and educating the community and health care workers on malaria.
What can travelers do to prevent malaria?
Because malaria is spread by mosquito bites, travelers to Gauteng Province should prevent mosquito bites. Ways include using insect repellent when outdoors, wearing protective clothing, and sleeping in an air-conditioned or well-screened room or under an insecticide-treated bed net.
