Vector-borne diseases and their control.
Control of the vector is usually a crucial factor in control programs for tropical diseases spread by insect vectors. Successful control programs aim at vulnerable points in the interactions between the vector, the reservoir host, the pathogen, the human host, and the environment. The objective is to prevent potential transmission, or interrupt actual transmission, by reducing the abundance, longevity, or host contact of the vector--whichever is most appropriate to the particular pathogen or disease and the local situation. The importance of individual assessment in the light of local conditions and a knowledge of the biology of the local vector is stressed. The vector-borne diseases discussed here are malaria, filariasis, arbovirus diseases, trypanosomiasis, leishmaniasis, plague and rickettsiosis.
