Vector Transmission of Animal Viruses

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

Modes of vector transmission vary markedly among arboviruses. Transmission typically occurs horizontally between competent arthropod vectors and susceptible vertebrate hosts, but also can occur vertically within vector populations by transovarial, trans-stadial, or veneral passage. The force of transmission or vectorial capacity determines the case dissemination rate and depends upon vector abundance, blood meal host selection, survival, susceptibility, and virus developmental rates. Susceptibility, or vector competence, is determined in the laboratory and is determined by the ability of the vector become infected with and transmit an acquired virus. In nature, transmission typically is sporadic and consists of maintenance, amplification or epidemic, and subsidence phases. Amplification typically is asymptotic and epidemics typically are delineated by the duration of favorable environmental conditions, numbers of susceptible hosts, and the intensity or efficacy of intervention. Risk factors include age, place of residence, climate, socioeconomic status and occupation - situations that bring virus, vector, and host together in time and space.
