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.
Avian malaria
Its real vector in Hawaiʻi is the mosquito "Culex quinquefasciatus", which was introduced to the Hawaiʻian Islands in 1826. Since then, avian malaria and avipoxvirus together have devastated the native bird population, resulting in many extinctions. Hawaiʻi has more extinct birds than anywhere else in the world; just since the 1980s, 10 unique birds have disappeared.
