Causes and Symptoms of Malaria
Malaria is mainly caused by parasitic protozoa, which spends most of its life in the red blood cells of humans. Malaria is spread by the female Anopheles mosquito, which transmit the parasites by first ingesting them from an infected person’s blood and then injecting the parasite in to an healthy person.
Plasmodium falciparum – this is the only parasite that causes malignant malaria. It causes the most severe symptoms and results in the most fatalities.
