Abstract
Since the spread of the COVID-19 virus among people all around the world, authorities have adopted various policies against it. Effective policies are usually based on strong academic support. Scholars have done a lot of research on the development of the virus and the epidemic. Compartmental models are widely used to solve infectious diseases related problems. Based on the extensive research on the COVID-19 virus by previous scholars, it is verified that there is a significant latency period when susceptible are transferred into exposed. Hence, the SEIR model is widely used to model the COVID-19 epidemic. And in this paper, we use a revised SEIR model to highlight the significance of the limitation term, analyzing the trend of the epidemic under the different methods of isolations. The research data is based on the outbreak of the epidemic in Nanjing in July 2021. The paper examines that isolation is one of the most effective measures to cut off the transmission route of COVID-19.
