Vector competence and insect capacity of infection transmission

Abstract

The most important parameters of infection transmission: vector competence and vector ability of transmitters, elements of genesis of vector-borne diseases and intrabody pathology of insects are briefly described. Emergent occurrence and spread of vector-borne exotic diseases in nonendemic areas can be considered as a precursory warning of pandemic threat caused by infectious agents including pre-viously unknown agents of new areas and ecological zones. Epidemiological sig-nificance of arboviral mosquito-borne infection is being discussed.
