Malaria is a mosquito-borne disease caused by Plasmodium parasites. It is transmitted through the bites of infected Anopheles mosquitoes. The disease is widespread in tropical and subtropical regions around the equator, including Sub-Saharan Africa, Asia, and Latin America. Malaria causes symptoms like fever, chills, and flu-like illness. It is typically diagnosed by examining blood slides under a microscope. Treatment depends on the species of Plasmodium, with drugs like chloroquine and antifolates being used. Prevention involves reducing mosquito bites through insecticides, bed nets, and protective clothing. Malaria control projects aim to study and reduce the burden of the disease.
