Why is malaria most prevalent in Africa?

Africa is the most affected due to a combination of factors:

A very efficient mosquito (Anopheles gambiae complex)

is responsible for high transmission. The predominant parasite species is Plasmodium falciparum , which is the species that is most likely to cause severe malaria and death.

Is Serengeti malaria free?
