Malaria Transmission in Sahelian African Regions, a Witness of Climate Changes

Int J Environ Res Public Health. 2022 Aug 16;19(16):10105. doi: 10.3390/ijerph191610105.


Climate changes in the eastern part of Sahelian regions will induce an increase in rainfalls and extreme climate events. In this area, due to the intense events and floods, malaria transmission, a climate sensitive disease, is thus slowly extending in time to the drought season and in areas close to the border of the desert. Vectors can as well modify their area of breeding. Control programs must be aware of these changes to adapt their strategies.

Keywords: Sahel; climate change; floods; malaria.
