Diseased caused by the malaria is protozoan P.falciparum .The mode of transmission of malaria is enters body from bite by infected anopheles mosquito and the parasite enters bloodstream and invades RBCs .The virulence factors of malaria is PfEMP1 and rifin proteins are the virulence factors.The diagnostic test for malaria is Rapid malaria test or antigen testing it is( the quickest test for malaria).The other test like molecular test ( it helps to identify the types parasite),drug resistence test and complete blood test.
