The impact of different rates on the epidemic. (a) The impact of different outflow rates on the epidemic when the outflow of population is greater. After the epidemic has been basically controlled, the impact of the urban population decreasing on the epidemic situation is small. (b) The impact of different inflow rates on the epidemic when the inflow of population is greater, and the -axis is extended to 100 days to see the trend. has little impact on the epidemic when it is relatively small (). While varying from 0.14 to 0.20, the epidemic is getting serious. Also, it will lead to the outbreak of the epidemic again in a short time when .
