The coronavirus disease 2019(COVID-19)has evolved to a global pandemic since its inception in December 2019.Countries have responded to the epi-demics with different levels of responses and containment measures.Given the unprecedented pressure on nations'healthcare systems and the deaths so far,there is an urgent need to evaluate the ef-fects of the containment measures,which would be useful for countries to plan for their responses to counter the first or pos-sibly the second wave of the epidemic.There have been studies for the effects of COVID-19 control measures taken in China on disease transmission and public health interventions for Wuhan's outbreaks[1-4],and Wuhan travel ban on the spread of COVID-19 both inside China and internationally[5,6].
