报告摘要：
The outbreak of COVID-19 caused by SARS-CoV-2 is a growing global concern. Delay in diagnosis and limited hospital resources lead to a rapid spread of COVID-19. In this talk, the effect of delay in diagnosis on the disease transmission is investigated with a new formulated dynamic model. Sensitivity analyses and numerical simulations reveal that, improving the proportion of timely diagnosis and shortening the waiting time for diagnosis can not eliminate COVID-19 but can effectively decrease the basic reproduction number, significantly reduce the transmission risk, and effectively prevent the endemic of COVID-19. More rigorous prevention measures and better treatment of patients are needed to control its further spread.
