报告摘要：There are many challenges to quantifying and evaluating the impact of behavior changes on the disease spread and control. In this talk, we propose several mathematical models to fully investigate impact of behavioral changes on transmission dynamics of infectious diseases. Initially, I proposed the model with nonlinear incidence rate with/without delays to represent the effect of individuals’ psychological and behavioral changes. We apply this modelling approach to examine media impact on control of Covid-19 infection based on the multisource data. Then we proposed a multi-scale model which explicitly models both the disease transmission and information transmission to evaluate the effect of behavior changes on dynamic behaviors. Finally, I include the imitation dynamics to investigate how behavior changes, vaccination and relaxation of non-NPIs affect the development of COVID-19 infections. Finally  I shall give some considerations and thoughts on modelling behavioral changes.
