en-us	China's decision to lock down the city of Wuhan may have prevented more than 700,000 COVID-19 cases by containing the spread of the coronavirus, according to a study published in the journal Science on Tuesday. 
zh-cn	当地时间 3 月 31 日，《科学》杂志在线发表的一项研究认为，自 1 月 23 日起实行的封城等措施让中国新冠肺炎感染者的总病例数减少了 96%，可能阻止了超过70万病例的出现，对疫情的遏制起到了至关重要的作用。 

en-us	Drastic Chinese control measures in the first 50 days of the epidemic bought other cities across the country valuable time to prepare and install their own restrictions, says the paper authored by researchers from China, the United States and the UK. 
zh-cn	这项研究题为“对中国 COVID-19 疫情暴发的最初 50 天内传播控制措施的调查”由22 位科学家联合完成，他们来自中国、美国和英国的 15 家机构 。 

en-us	By day 50 of the epidemic - February 19 - there were 30,000 confirmed cases in China, said Oxford fellow Christopher Dye, one of the paper's authors. 
zh-cn	研究人员表示，截至 2 月 19 日，也就是疫情首次公开通报后的第 50 天，中国已有30,000例确诊病例。

en-us	"Our analysis suggests that without the Wuhan travel ban and the national emergency response there would have been more than 700,000 confirmed COVID-19 cases outside of Wuhan by that date," he was quoted as saying in a press release. "China's control measures appear to have worked by successfully breaking the chain of transmission – preventing contact between infectious and susceptible people." 
zh-cn	而如果没有武汉的出行禁令和中国各省市的紧急应对措施重大突发公共卫生事件一级响应，武汉以外可能会出现超过70万例的疫情暴发。中国的控制措施成功地阻断了传播途径——防止感染人群和易感人群间的接触。 

en-us	The researchers used a combination of case reports, public health information and mobile phone location tracking to investigate the spread of the virus. 
zh-cn	研究人员试图结合病例报告，公共卫生信息和手机位置跟踪功能来研究病毒的传播，并探讨人类活动的作用、旅行限制和社会距离措施在预防传染病传播方面的有效性。 

en-us	The Wuhan shutdown delayed the arrival of the virus in other cities, their model showed, giving them time to prepare by banning public gatherings and closing entertainment venues, among other measures. 
zh-cn	武汉的出行禁令推迟了COVID-19在其他城市的暴发时间，从而使这些城市有时间通过禁止公共聚会和关闭娱乐场所等方式进行防控准备。 

en-us	But when Beijing first shut down Wuhan more than two months ago, the decision was seen as a dramatic escalation in the fight against infection. 
zh-cn	两个月前，对于武汉的出行禁令被全世界视为这场战“疫”的戏剧性升级。

en-us	Nearly half of humanity in the world has now been told to stay home to curb the spread of the virus, and lockdowns are rapidly becoming normalized. 
zh-cn	但目前，世界上已有近半人口被要求呆在家里，而“封城”也快速成为控制疫情的必要手段。 

en-us	With the restrictions in the city slowly being lifted and life inching closer to normal, the question for China and other countries around the globe is what will happen once movement resumes. 
zh-cn	随着城市逐渐解封，人们生活渐趋正常，中国和其他一些国家要认真思考，疫情防控的下一步是什么。
