tailieunhanh - Emerging vector borne diseases in a changing environment

Vector-borne infectious diseases are emerging or resurging as a result of changes in public health policy, demographic and societal changes, insecticide and drug resistance, shift in emphasis from prevention to emergency response, genetic changes in pathogens in the last two decades of the twentieth century. This paper will provide an overview of the distribution, reasons of emergence or reemergence of the important vector-borne diseases throughout the world. | Turk J Biol 29 (2005) 125-135 © TÜB‹TAK Review Article Emerging Vector-borne Diseases in a Changing Environment Nurdan ÖZER Department of Biology, Facultyof Science, Hacettepe University, 06532 Beytepe, Ankara - TURKEY Received: Abstract: Vector-borne infectious diseases are emerging or resurging as a result of changes in public health policy, demographic and societal changes, insecticide and drug resistance, shift in emphasis from prevention to emergency response, genetic changes in pathogens in the last two decades of the twentieth century. 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 .
