Definition of malaria
A disease spread by mosquitoes, in which a protozoan, Plasmodium, multiplies in blood every few days.
Examples of malaria in the following topics:
- Protist parasites include the causative agents of malaria, African sleeping sickness, and waterborne gastroenteritis in humans.Plasmodium Species Members of the genus Plasmodium must colonize both a mosquito and a vertebrate to complete their life cycle.
- Of the four Plasmodium species known to infect humans, P. falciparum accounts for 50 percent of all malaria cases and is the primary cause of disease-related fatalities in tropical regions of the world.
- In 2010, it was estimated that malaria caused between one and one-half million deaths, mostly in African children.
- During the course of malaria, P. falciparum can infect and destroy more than one-half of a human’s circulating blood cells, leading to severe anemia.
- P. falciparum is transmitted to humans by the African malaria mosquito, Anopheles gambiae.
- Another common parasite is Plasmodium falciparum, the protozoan cause of malaria, a significant disease in many parts of the world.
- Thus, malaria is spread from human to human by mosquitoes, making it one of many arthropod-borne infectious diseases.
- This group includes the genus Plasmodium, which causes malaria in humans.
