QUESTION
What percent of Africa has malaria?
ANSWER
That is very difficult to measure, but maps of malaria transmission potential show that malaria is potentially present across most of the continent, excluding the heart of the Sahara and Kalahari deserts, and the highlands of Ethiopia, Lesotho and Uganda/Rwanda. Other parts of the continent, such as the coastline of North Africa (along the Mediterranean) and much of South Africa and Zimbabwe likely only experiences seasonal transmission of malaria, with some parts of the year too cold and/or dry to support transmission. The below map shows the distribution of malaria throughout Africa, and should give you some idea of the percentage landcover that is affected.
