摘要內容:
Abstract. West Nile virus (WNv) is a mosquito-borne disease caused by Flavivirus. To investigate the combined effects of vertical transmission, temperature-dependent incubation periods and environmental heterogeneity on the transmission of WNv, we develop a delay differential system with stage-structure and time-varying delays. We then derive the mosquito reproduction number and WNv reproduction number, respectively, and further show that these two numbers serve as threshold parameters that determine whether WNv will spread or not.
Numerical simulations support our analytic results and suggest that time-periodic delays and environmental heterogeneity can play important roles in the WNv dynamics
