报告摘要:West Nile virus was first introduced to Canada in 2002, it has caused more than 2000 human deaths and death of millions of avian birds in North America. I will start with an introduction and review of compartmental models for the transmission of West Nile virus, and present the threshold dynamics for the risk assessment and for forecasting of West Nile cases, which will lay the groundwork for predictive models of West Nile virus cases.  In reality, it is the weather conditions, such as daily average temperature and precipitation, affect not only the abundance and the biting behavior of vector mosquitoes, but also determine the outbreak and spread of West Nile virus. I will then introduce a weather-driven statistical model for the abundance of Culex mosquitoes, and incorporating both temperature and precipitation in a compartmental model for the transmission of West Nile virus among mosquitoes, birds, and humans, we develop a predictive model for weekly forecasting of West Nile virus risk in Peel Region, Ontario Canada. With the weekly surveillance data for West Nile virus in Peel Region, we numerically simulate and explore how different weather conditions affect the transmission of the virus in the area. Such a hybrid modeling approach allows us to develop the forecasting tools for West Nile virus and other mosquito-borne diseases. I will end the talk by presenting some challenging problems of forecasting West Nile virus cases.
