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.
Aedes aegypti
The mosquito carries a disease that is widespread in tropical South America and Africa, and often come out in moderate regions during the summer time. Today, the "Aedes aegypti" is found around the southeast region of the U.S., but is slowly decreasing due to competition with other mosquitoes, such as "Aedes albopictus".
