No, the sun cannot cause malaria.
Malaria is caused by parasites, specifically Plasmodium parasites, and is transmitted to humans through the bites of infected female Anopheles mosquitoes. The sun plays absolutely no role in the transmission or development of malaria.
Many people mistakenly associate malaria with being outside or exposed to the sun, but this is simply because mosquitoes, the vectors of the disease, are often more prevalent outdoors, particularly during certain times of the day.
To reiterate, the only cause of malaria is the Plasmodium parasite, which is spread by infected Anopheles mosquitoes. Avoiding mosquito bites, through measures like using insect repellent, wearing protective clothing, and sleeping under insecticide-treated nets, is the best way to prevent malaria.
