The first evidence of malaria parasites was found in mosquitoes preserved in amber from the Palaeogene period that are approximately 30 million years old. Human malaria likely originated in Africa and coevolved with its hosts, mosquitoes and non-human primates.
Why is malaria so common 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.

Some population groups are at considerably higher risk of contracting malaria, and developing severe disease, than others.
Is malaria a virus?
A: Malaria is not caused by a virus or bacteria. Malaria is caused by a parasite known as Plasmodium, which is normally spread through infected mosquitoes.
Where did Malaria originally come from?

Algeria became the third country in Africa to be officially certified malaria-free in 2020 after Mauritius (1973) and Morocco (2010). Its malaria elimination programme was fully funded through domestic sources.
Why is there no malaria in America?
Malaria transmission in the United States was eliminated in the early 1950s through the use of insecticides, drainage ditches and the incredible power of window screens. But the mosquito-borne disease has staged a comeback in American hospitals as travelers return from parts of the world where malaria runs rampant.
