A statistical transmission model for COVID-19 outbreak, with adjustment of external factors
Speaker:
Dr. Yifan Zhu, Staff Scientist, Fred Hutchinson Cancer Research Center
Abstract:
The COVID-19 pandemic showed some resemblances to previous outbreaks caused by coronaviruses such as SARS and MERS. However, by combing features such as relatively high transmission rate, potential of asymptomatic/pre-symptomatic infection and high case fatality rate among the vulnerable, this virus has presented significant challenges to public health systems. In this talk, I will introduce a statistical model for inferencing the transmission dynamics of COVID-19 outbreak incorporating some special features of the virus, and the approaches to combine certain spatial, temporal, social and demographic factors into the model. Early analytical results applied to the observed epi-curves in Wuhan, China enabled us to understand the outbreak monitoring data in other regions. We will present some preliminary inferences for the ongoing COVID-19 outbreak data from several US states.
