Yare no yɛ The mosquito bite introduces the parasites from the mosquitos saliva into a persons blood.[1] The parasites travel to the liver where they mature and reproduce. Five species of Plasmodium can infect and be spread by humans.[2] Most deaths are caused by P.xa0falciparum because P.xa0vivax, P.xa0ovale, and P.xa0malariae generally cause a milder form of malaria.[1][2] The species P.xa0knowlesi rarely causes disease in humans.[1] Malaria is typically diagnosed by the microscopic examination of blood using blood films, or with antigen-based rapid diagnostic tests.[2] Methods that use the polymerase chain reaction to detect the parasites DNA have been developed, but are not widely used in areas where malaria is common due to their cost and complexity.[3]
