Description
Summary:The Aedes mosquito species are capable of maintaining the circulation of viruses only by the strategy of transovarial transmission and diapause of eggs. It is found that when the transovarial transmission is inhibited, the survival time of the presence of viruses in a given mosquito habitat is limited from above by the eggs lifetime. In contrast, when the transovarial transmission is turned on, the infection persistence time may largely exceed both the eggs lifetime and flooding period depending upon the production rate of infected eggs. We present a simple model allowing the derivation of analytical expressions of the infection persistence time.
