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.
Hot zone (environment)
In Peru deforestation is leading to the distribution of Malaria. With the forests being destroyed the wildlife is as well, leaving malaria looking for a new host. Malaria is a very dangerous disease, so much so that vaccinations are required for traveling into places suspected of housing the disease. Malaria is a disease that is found predominantly in third world, low-income countries. Malaria along with other insect diseases are learning to adapt to life in the city. In Peru a port city called Iquitos the population has been growing in the past 10 years making it prime for mosquitoes to flourish. These mosquitoes also bring in Dengue Fever, in which 5 percent of its victims will die.
