Malaria is a serious disease carried by mosquitoes which causes periods of fever. a disease that is common in hot countries and that you get when a type of mosquito bites you (mala aria ; because it was believed that the disease came from gases rising from wet land). A serious relapsing infection caused by protozoa of the genus Plasmodium (see plasmodium), transmitted by the bite of the Anopheles mosquito. Known since before the 5th century BC, it occurs in tropical and subtropical regions near swamps. The roles of the mosquito and the parasite were proved in the early 20th century. Annual cases worldwide are estimated at 250 million and deaths at 2 million. Malaria from different Plasmodium species differs in severity, mortality, and geographic distribution. The parasites have an extremely complex life cycle; in one stage they develop synchronously inside red blood cells. Their mass fissions at 48-or 72-hour intervals cause attacks lasting 4-10 hours. Shaking and chills are followed by fever of up to 105 °F (40.6 °C), with severe headache and then profuse sweating as temperature returns to normal. Patients often have anemia, spleen enlargement, and general weakness. Complications can be fatal. Malaria is diagnosed by detecting the parasites in blood. Quinine was long used to alleviate the fevers. Synthetic drugs, such as chloroquine, destroy the parasites in blood cells, but many strains are now resistant. Carriers of a gene for a hemoglobinopathy have natural resistance. Malaria prevention requires preventing mosquito bites: eliminating mosquito breeding places and using insecticides or natural predators, window screens, netting, and insect repellent.

A human disease, caused by parasites, that is characterized by periodic attacks of chills and fevers; it is transmitted by certain species of mosquito
A disease caused by infection with one or more of four different protozoans and marked by recurring fevers, prostration, and sometimes death The protozoa are spread from one infected person to another by the bite of Anopheles mosquitoes and, rarely, via blood transfusion
A disease of humans caused by blood parasites of the species Plasmodium falciparum, vivax, ovale or malariae and transmitted by anopheline mosquitoes
A morbid condition produced by exhalations from decaying vegetable matter in contact with moisture, giving rise to fever and ague and many other symptoms characterized by their tendency to recur at definite and usually uniform intervals
an infective disease caused by sporozoan parasites that are transmitted through the bite of an infected Anopheles mosquito; marked by paroxysms of chills and fever

Malaria is caused by the protozoa 4 plasmodia and is spread by female mosquitos Infection by the 4 plasmodia protozoa begins in humans when an infected female mosquito bits her victim and transfers to protozoa from her saliva to the victim's bloodstream
A disease caused by the presence of the sporozoan Plasmodium in human or other vertebrate red blood cells, usually transmitted to humans by the bite of an infected female mosquito of the genus Anopheles that previously sucked the blood from a person with malaria Human infection begins with the exoerythrocytic cycle in liver parenchyma cells, followed by a series of erythrocytic schizogenous cycles repeated at regular intervals; production of gametocytes in other red cells provides future gametes for another mosquito infection; characterized by episodic severe chills and high fever, prostration, occasionally fatal termination (Dirckx, 1997)
