Malaria is a disease caused by parasites of the genus Plasmodium, which are transmitted to people through the bites of infected mosquitoes. The infected mosquitoes are generally of the Anopheles genus. Once a person is bitten by an infected mosquito, the parasites enter the bloodstream and head towards the liver, where they multiply. Afterwards, the parasites return to the bloodstream and infect the red blood cells, causing symptoms such as fever, chills, sweating, headaches, and sometimes severe complications like anemia and kidney failure. Malaria is widespread in many parts of the world, mainly in tropical and subtropical regions, and can be prevented through the use of mosquito nets, insect repellents, and prophylactic drugs.
