How will climate change affect malaria?

The Anopheles mosquito, which is primarily found in Africa and the regions surrounding the equator, breeds best in hot climates. This is because the mosquito prefers warm weather for breeding, which speeds up the process of malaria transmission.

Since neither species of mosquito can survive in cold climates, only humans would be the "vectors" in that scenario, though it goes without saying that they would not spread the disease by moving around much.

Climate change is expected to impact malaria transmission by altering the geographical range and seasonal patterns of the disease. Warmer temperatures can increase the reproductive rate of mosquitoes, leading to higher transmission rates. Changes in precipitation patterns can create breeding habitats for mosquitoes, expanding the areas at risk for malaria transmission. Additionally, shifts in temperature and humidity can influence the development and survival of the malaria parasite within mosquitoes, further affecting transmission dynamics. Overall, climate change is likely to exacerbate the spread and burden of malaria in many regions.
