報告摘要:There are many challenges to quantifying and evaluating the media impact on the control of emerging infectious diseases. In this talk, we propose several mathematical models to fully investigate media impact on transmission dynamics of infectious diseases. Initially, we formulate a implicit model to describe the incidence depending on the number of infected individuals and changing rate, and examine the dynamics. Then I propose a model by including both the response time for mass media and for individuals’ behavior changes. With two time delays, we comprehensively investigate the local and global bifurcation, and main results show that either the media described feedback cycle, or time delays can induce Hopf bifurcation and result in periodic oscillations. Further, we parameterized the proposed model on the basis of the 2009 A/H1N1pandemic influenza data in Shaanxi province, China, and estimated the basic reproduction number and the time delay. Finally, we extend the model by including the variable of the news item and apply this modelling approach to examine media impact on control of Covid-19 infection based on the multisource data.
