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.
Environmental health policy
The temperature affects the malaria parasites in the mosquitoes and its ability to incubate as well as how likely the mosquitoes are to blood feed. Mosquitoes thrive in the transmission of parasites where temperatures do not exceed 25 degrees Celsius. Excessive rain, which is becoming more frequent amongst many countries, acts as the perfect breeding site for the aquatic beginning of a mosquito's life. Malaria is a vector- borne disease that is extremely prevalent in Africa. The disease puts billions of people at risk of contracting the virus. Due to a lack of sufficient healthcare where the disease is most concentrated, many people die. The environment is a huge contributor to the success malaria has in transmitting the disease.
