#### ABSTRACT

This article mainly studies the infectious disease model of COVID-19. Based on the SEIR model, the epidemic prevention and control are divided into two stages according to my country's national conditions. The subjects of the study are normal people, lurking people, confirmed people, cured people, and dead people. Establish differential equation models and solve parameters for analysis and prediction. At the same time, the basic infection number is defined to compare the size of the basic infection number in the two cases of China's unmanned intervention and related prevention and control measures, and draw the conclusion that China's epidemic prevention and control policy is obviously effective.
