The disease transmitted through the bite of an infected mosquito is malaria. This infectious disease is caused by parasites from the genus Plasmodium, which multiply within the mosquito and are passed to humans when the mosquito bites. Symptoms of malaria include high fever, chills, headaches, and flu-like illness, and it can be severe or even fatal if not treated promptly. Malaria is primarily found in tropical and subtropical regions, particularly in sub-Saharan Africa. Preventive measures include the use of insecticide-treated bed nets, antimalarial medications, and mosquito control strategies to reduce transmission.
