Malaria is a serious and sometimes fatal disease caused by a parasite that is transmitted from one human to another by the bite of infected mosquitoes. In humans, the parasites migrate to the liver where they mature and release more parasites. These enter the bloodstream and infect the red blood cells.
The parasites multiply inside the red blood cells, which then rupture within 48 to 72hours, infecting more red blood cells. The first symptoms usually occur 10 days to 4 weeks after infection, though they can appear as early as 8 days or as long as a year later.
Symptoms of malaria include fever, headache, naussea and vomiting, and joint and muscle pain. If not treated, malaria can quickly become life-threatening by disrupting the blood supply to vital organs.
