ABSTRACT
Novel Coronavirus Pneumonia (COVID-19) has ravaged the world since 2019, seriously affecting human production and life. Although my country has controlled the epidemic on the whole, there are still local outbreaks. To this end, a classic infectious disease SEIR model was established to study the spread of the new coronavirus pneumonia epidemic. The population was divided into four categories: susceptible population, exposed population, infected population and removed population. After the parameters of the SEIR model were determined, Python was applied to conduct drills on the SEIR model, and simulation analysis was conducted on the epidemic transmission in Taiwan and Guangdong provinces with and without control measures. The results show that there are significant differences in the number of exposed, infected, and removed numbers between the two provinces. It shows that early and timely strict prevention and control measures can effectively control the spread of the new coronavirus pneumonia epidemic. © 2021 ACM.
