Malaria is a serious and sometimes fatal disease caused by a parasite that commonly infects a certain type of mosquito which feeds on humans.
Malaria may also be transmitted from a mother to her unborn infant before or during delivery ("congenital" malaria).
Malaria parasites, which grow and develop inside the mosquito, need warmth to complete their growth before they are mature enough to be transmitted to humans.

 MDTravel Health - Malaria - Lariam, Malarone, and other drugs
Malaria is a parasitic infection of red blood cells and the liver caused by any of four related species: Plasmodium falciparum, P. vivax, P. ovale, and P. malariae.
Infections caused by P. falciparum are particularly dangerous because of a propensity for infected red blood cells to obstruct blood flow to the brain, causing seizures, impaired consciousness, and sometimes coma.
Malaria prophylaxis should be resumed one week after the first treatment dose, unless quinine has been used for self-treatment and mefloquine for prophylaxis, in which case mefloquine should be resumed one week after the last dose of quinine.

Malaria is perhaps even tougher to combat than HIV or tuberculosis because of its multiple distinct life-cycle stages and its genetic complexity, which allows Plasmodium to adapt rapidly to drugs and to our immune system's efforts to render it ineffective.
