Xue L, Jing S, Sun W, et al. - The movement of humans has expanded the geographic distribution of the ongoing COVID-19 pandemic and caused subsequent local outbreaks. Hence, researchers sought to ascertain the effect of human mobility and travel ban on the transmission and spatial spread while minimizing the influence on social activities and national economics. They herein constructed a mobility network model for spatial epidemics explicitly considering time-varying inter-province and inner-province population flows, spatial heterogeneity in terms of disease transmission, as well as the impact of media reports. Occurrence of the second outbreak was observed approximately on March 1, 2020. By March 15, 2020, there was an increase in the cumulative cases by 70.6% without a travel ban. Inter-province travel was mainly responsible for the increase in cumulative cases. A severe secondary wave was successfully prevented in China by the strict travel ban.
