Vector borne diseases are infectious diseases spread through transmitters through disease-causing organisms typically identified as arthropods—invertebrate animals—although technically vertebrates can also become vectors. More than 85 percent of vectors are arthropods. They affect the health of the human population through stings, bites, or infestation. Considered most significant and widespread form of vector borne disease transmission is the bite of blood-feeding arthropods, especially mosquitoes.
Three factors comprise the transmission of vector borne diseases to humans: the pathologic agent, the arthropod vector, and the human host. Most of known vector borne diseases subsist through their animal hosts. Moreover, vector borne diseases are prevalent in the tropics and subtropics and are relatively less occurring in temperate zones.
Presented under this category are sites that provide various information and resources about vector borne diseases in different parts of the world, as transmitted by different kinds of vectors.
