Abstract
COVID-19, a worldwide pandemic, has had negative implications on the global economy and politics. Previous studies, based on the SIR Model and its variations, divided the population of a single area into the suspected, the infected and the recovered and other parts, and proposed corresponding dynamic systems to simulate the development of the epidemic. However, the movement of people from one region to another can lead to the spread of COVID-19 from one region to another. We establish SIR Model for the transmission of the epidemic between two regions, and theoretically derived the disease-free equilibrium point and the basic reproduction number of the proposed dynamic system. Next, we study the effect of population mobility rate between different regions on the basic reproduction number. Finally, we carry out numerical simulation of the model and analyze the development of the epidemic under the parameter hypothesis. These results have clinical and guiding implications for epidemic prevention and control in different regions.
