The present invention provides an easy and rapid method for detecting/identifying the presence or absence of specific Plasmodium parasites and four species of malaria parasites in a human specimen, an anti-malaria measure support system, and a malaria infection-prevention/treatment system, which can contribute to practical diagnosis in a malaria endemic area. According to the present invention, using a genus-specific primer set that can detect four Plasmodium parasites that infect humans at a time, and the primer sets each specific to each of four species of Plasmodium parasites (P. falciparum, P. vivax, P. malariae, and P. ovale), the presence or absence of infection with these parasites can be detected/identified easily and rapidly.
