【讲座内容简介】Since the global outbreak of COVID-19, the COVID-19 disease caused by the novel coronavirus SARS-CoV-2 has had an unprecedented spreadand continue to cause an increasing number of fatalities worldwide. Predicting the transmission dynamics of the novel coronavirus and access the efficacy of control strategies presents us a great challenge. In this talk I shall introduce multiple data related to the epidemic data, which help us effectively investigate transmission dynamics of COVID-19. Then I summarize our work on early/long-term predictions, efficacy of control measures, and impacts of limitation of medical resources, mass media on transmission dynamics, by fitting the proposed model to the multi-source data. Then, I shall investigate how we combine the network dynamic models with the big data of population movement to study the impact of resumption of work and population flow on the possible second outbreak, and investigate the optimal reopening strategy during COVID-19 pandemic.

This is a joint work with Professor Wu Jianhong's group (York University, Canada) and Prof Tang Sanyi's group (Shaanxi Normal University).
