Mosquito
Mosquito-borne diseases are currently most prevalent in East Africa, Latin America,  Southeast Asia, and India; however, emergence of vector-borne diseases in Europe have recently been observed. A weighted risk analysis demonstrated associations to climate for 49% of infectious diseases in Europe including all transmission routes. One statistical model predicts by 2030, the climate of southern Great Britain will be climatically-suitable for malaria transmission "Plasmodium vivax" malaria for 2 months of the year. By 2080 it is predicted that the same will be true for southern Scotland.
Plasmodium vivax
"Plasmodium vivax" is found mainly in Asia, Latin America, and in some parts of Africa. "P. vivax" is believed to have originated in Asia, but latest studies have shown that wild chimpanzees and gorillas throughout central Africa are endemically infected with parasites that are closely related to human "P. vivax." These findings indicate that human P. vivax is of African origin". Plasmodium vivax" accounts for 65% of malaria cases in Asia and South America. Unlike "Plasmodium falciparum", "Plasmodium vivax" is capable of undergoing sporogonic development in the mosquito at lower temperatures. It has been estimated that 2.5 billion people are at risk of infection with this organism.
