COVID-19 has quickly spread to over 210 countries and territories worldwide and infected more than 7.4 million individuals and caused 415,000 deaths globally. In this talk, Professor Lin will provide a historical overview of the epidemic in Wuhan, then provide the analysis results of 32,000 lab-confirmed COVID-19 cases in Wuhan to estimate the transmission rates and evaluate the effects of different public health interventions on controlling the COVID-19 outbreak, such as social distancing, isolation and quarantine, as well as summarizing the epidemiological characteristics of the cases. The results show that multi-faceted intervention measures successfully controlled the outbreak in Wuhan. She will also present the estimated transmission rates in USA and other countries and intervention effects using social distancing, test-trace-isolate strategies.
