The experimental simulation results show the impact of social distancing and migration-in rates on reducing the total number of infections and the basic reproductions. Thus, in this paper, we incorporate asymptomatic infections and population migration into SEIR and introduce a new model, which will be referred to as the SEIAR (Susceptible-Exposed-Infectious-Asymptomatic-Recovered) model with population migration. • By establishing a mathematical model of an infectious disease based on the characteristics of COVID-19 (such as the effect of asymptomatic infected patients in spreading the virus), the applicability of the modified model is proved. Currently, based on a simple mathematical model and limited data, Zhong et al., [7] used the epidemic data of in Wuhan (at the initial stage) to estimate the infection rate, mortality, and other parameters.	./cache/cord-289496-d8ac6l6o.txt	./txt/cord-289496-d8ac6l6o.txt
