Climate change could see a 20 percent rise in malaria cases in coastal southern Africa.

Climate change is poised to expose more people to malaria in cooler parts of Africa by the end of the century, with cases potentially rising as much as 20% in coastal southern Africa, according to a new study published in Nature.
By 2050, rising temperatures are projected to expand the range of malaria-carrying mosquitoes into cooler parts of southern and eastern Africa, increasing cases by about 5% in the East African highlands - including parts of Kenya and Ethiopia - as well as in Angola, Zambia and eastern South Africa, the study found.
The reverse is expected in some of Africa’s hottest regions, where transmission is projected to fall by about 5% in countries including Nigeria, Burkina Faso and Mali. In parts of the Sahel, conditions may become too hot for mosquitoes to survive, potentially eliminating the disease altogether.
