Vectorborne Viral Infections

Viruses can also be transmitted by the bite of anthropod insects like mosquitoes, ticks, triatomine bugs, sandflies, and blackflies. The diseases caused by these vectors are termed as vectorborne viral infections. Vectors are capable of causing several types of infections. Arthropod vectors are cold-blooded (ectothermic) and thus especially sensitive to climatic factors. Weather influences survival and reproduction rates of vectors, in turn influencing habitat suitability, distribution and abundance; intensity and temporal pattern of vector activity (particularly biting rates) throughout the year; and rates of development, survival and reproduction of pathogens within vectors. However, climate is only one of many factors influencing vector distribution, such as habitat destruction, land use, pesticide application, and host density.
