Malaria

Vector – Anopheles gambiae

As a primary vector for malaria, it’s difficult to overestimate the impact this mosquito species complex has had on humanity. While mostly eradicated in many parts of the world, malaria still causes hundreds of thousands of deaths each year, with the great majority of those deaths occurring in Africa.

Pathogen

Malaria is a life-threatening disease caused by Plasmodium spp. parasites prevalent in much of the tropics. Once in the bloodstream, the parasite travels to the liver, where it infects and ruptures liver cells. In its next stage of development, the parasite migrates back into the bloodstream and invades red blood cells, multiplying until the red blood cells burst and release more parasites. This ongoing cycle causes various symptoms including chills, fever, jaundice, and anemia.
