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 vexans
"A. vexans" is a known vector of "Dirofilaria immitis" (dog heartworm), myxomatosis (a deadly rabbit viral disease), and Tahyna virus, a seldom-diagnosed "Bunyaviridae" virus, which affects humans in Europe, causing a fever which disappears after 2 days, but afterward can cause encephalitis or meningitis. "A. vexans" is the most common mosquito in Europe, often comprising more than 80% the European mosquito community. Its abundance depends upon availability of floodwater pools. In summer, up to 8,000 mosquitoes can be collected per trap per night. "A. vexans" exhibited significantly higher transmission rates of Zika virus than "A. aegypti", and its wide geographic distribution, periodic extreme abundance, and aggressive human biting behavior increase its potential to serve as a Zika virus vector in northern latitudes outside the range of the primary vectors "A. aegypti" and "A. albopictus".
