講　題：Differential equations modeling the transmission of West Nile virus

摘   要：

West Nile virus (WNv), a mosquito-transmitted arbovirus, is the most prevalent Flavivirus worldwide. Since its introduction in North America in 1999, it has become endemic throughout the contiguous United States as well as all Canadian provinces and has caused serious public health concern. WNv is maintained in a zoonotic cycle between reservoir birds and vector mosquitoes, and Culex mosquitoes are one of the most effective vectors for transmitting WNv. In this talk, I shall first propose a nonlocal and time-delayed system describing the WNv transmission in a spatially variable habitat, where a fixed latency in the mosquitoes is included. Next, we shall develop a delay differential system with stage-structure and time-varying delays to reflect the importance of temperature-dependent incubation periods and seasonality on the transmission of WNv. This talk is based on three of my recent works joint with collaborators.
