Climate changes also can influence the emergence and reemergence of these diseases which are malaria, dengue, yellow fever, plague, filariasis, louse-borne typhus, lyme disease, trypanosomiasis, leishmaniasis and viral diseases. West Nile virus is just the latest example of this type of invasion by exotic virus. This paper will provide an overview of the distribution, reasons of emergence or reemergence of the important vector-borne diseases throughout the world.

Bat› Nil virusu, ekzotik viruslar›n yay›l›m›na ait son örnektir. Bu makalede, önemli vektör kökenli hastal›klar›n da¤›l›m›, yeniden ortaya ç›k›fllar›n›n nedenleri global olarak özetlenmeye .
