Malaria is a deadly blood disease transmitted to humans through mosquitoes in which the person bit is infected with parasites that multiply in the liver where they eventually infect and destroy red blood cells, which carry oxygen throughout the body. Malaria occurs mostly in tropical areas of the world but hit a forty year record high in the United States in 2011. It can be treated if caught during the early stages of its development. Here are the causes, symptoms, and treatments.
Malaria occurs when an infected mosquito bites a human and injects a parasitic infection into the bloodstream where it lays dormant in the liver. After being bitten by an infected mosquito, the person affected will not show symptoms for up to sixteen days while the parasite begins to multiply asexually, or without a partner. The new parasites are released into the bloodstream where they infect red blood cells while other parasites remain in the liver. A mosquito becomes infected once it bites a person who already has the decease.
