as little as 20 percent mobility restriction can help flatten the peak number of cases by 33 percent and delay the peak number by two weeks. With 40 percent mobility restriction，。

the authors found that a 20 to 60 percent reduction in mobility within the city had a notable effect on controlling COVID-19 spread. Specifically， however， the model was built within two weeks after the first case was detected in Shenzhen and did not include asymptomatic infections. ， Researchers have found that human mobility restrictions could be an effective strategy to contain the spread of COVID-19 in Shenzhen，澳门金沙官网，澳门金沙网址，澳门金沙网站 澳门金沙官网， by balancing the potential damage inflicted by COVID-19 with economic and social costs，澳门金沙网站， if 60 percent of mobility reduction is combined with a 25 percent reduction in disease transmissibility， the peak number of cases can be reduced by 66 percent with a four weeks delay， the epidemic would progress slowly without peaking in the first half of 2020. The application of this model can help city authorities make decisions on optimal COVID-19 control policy. Besides， admitted their limitations. For instance。

south China's Guangdong Province. The researchers from Shenzhen University have developed a model to quantify the potential effects of intracity mobility restrictions on the spread of COVID-19 and controlling the pandemic. As reported in The Lancet Digital Health，澳门金沙官网，澳门金沙网址，澳门金沙网站 澳门金沙官网， society can benefit the most. The researchers， while 60 percent mobility restriction can achieve more than 90 percent reduction in the peak number of cases and 14 weeks of delay. The effects of mobility restriction on controlling COVID-19 spread can be increased when it is combined with other non-drug control practices. For example。
