Malaria is a terrible disease and often fatal. It is caused by a protozoan, a simple single-celled organism and carried by a specific type of mosquito. When one of these mosquitoes bites a person, it injects this protozoan, P. falciparum, into the individual. These parasitic cells take up residence in the blood and destroy red blood cells, the cells that carry oxygen through the blood. There is currently no vaccine against malaria.
