Malaria is caused by infection with protozoan parasites belonging to the genus Plasmodium transmitted by female Anopheles species mosquitoes. Our understanding of the malaria parasites begins in 1880 with the discovery of the parasites in the blood of malaria patients by Alphonse Laveran. The sexual stages in the blood were discovered by William MacCallum in birds infected with a related. . A widespread and potentially lethal human infectious disease, at its peak malaria infested every continent, except Antarctica. Its prevention and treatment have been targeted in science and medicine for hundreds of years Laveran won a Nobel Prize in 1907 in part for this discovery. In August 1897, in India, British bacteriologist Ronald Ross discovered parasites of a malaria of birds in the stomach of a Culex mosquito, and in 1898, in Rome, Giovanni Grassi and his colleagues discovered a parasite of human malaria in an Anopheles mosquito
