Usage

What is malaria? Malaria is the collective name of a potentially fatal group of diseases caused by parasitic organisms spread through bites of a particular mosquito.Symptoms of malaria include periods of fever, chills, and sweating followed by respiratory problems and organ failure and, finally, death. Malaria is preventable and, if it’s caught early, it is curable.Malaria is caused by a parasitic, microscopic organism known as a protozoan. At least four members of the genus Plasmodium are known to cause malaria in humans. These are P. falciparum, P. malariae, P. ovale, and P. vivax. P.knowlesi may also cause malaria.These protozoa enter the bloodstream through a bite from several different species of female mosquitoes from the genus Anopheles. The protozoa are more likely to live inside a mosquito with a long life and are more likely to enter humans if the mosquito has a tendency to bite humans instead of animals.The majority of species of Anopheles mosquitoes that fit both categories are native to Africa. For this reason, over 90 percent of the world’s malaria cases occur in Africa. In 2018, there were 228 million cases of malaria, with 405 thousand deaths.
