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.
Walter Myers (physician)
On 24 August Durham and Myers arrived in Pari (modern day Belem) in the northern state of Pará, Brazil, where they established a laboratory in Domingos Freire Hospital to study the transmission of the disease and were among the first to establish its transmission by mosquitoes. Durham and Myers were aware of the risks that they were taking; however, on 16 January 1901, after conducting the fourteenth autopsy on victims of yellow fever both men found they were themselves infected. They were transferred to the Domingos Freire Isolation Hospital in Pari where Durham recovered but Myers died four days later, aged 28. In his subsequent report Durham deduced that they had both been infected through mosquito bites.
