What are Vector Borne Diseases?
According to the World Health Organisation vector borne diseases are defined “as the diseases which are commonly transmitted through vectors” [1]. A vector is an organism that does not cause disease itself but which spreads infection by conveying pathogens from one host to another, for example the mosquitoes that carry the malaria parasite or dengue virus, snail hosts of schistosomiasis, or rodent reservoirs of leishmaniasis (a disease spread by a small Sandfly).
