从2019年底开始，中国武汉市出现了一种前所未有的新型冠状病毒，被世界卫生组织（世卫组织）命名为COVID-19。尽管全球采取了严格的遏制和隔离措施，但COVID-19的发病率仍在继续上升，截至5月中旬，全球确诊病例超过400万例，死亡病例超过30万例。本研究旨在以10个高感染国家为例，展示社会距离措施的颁布对COVID-19传播的影响。作者重点分析了包括美国在内的10个高感染国家的新冠肺炎确诊病例和死亡人数统计数据。2020年1月11日至5月2日期间，美国、西班牙、意大利、英国、法国、德国、俄罗斯、土耳其、伊朗和中国的疫情防控情况。分析社会距离措施与新冠肺炎确诊病例和死亡人数统计之间的关系，以阐明社会距离措施对10个高感染国家新冠肺炎传播的有效性。结果显示，从最高水平的社会距离措施颁布到每天的确诊病例和死亡人数出现下降迹象，需要1 -4周的时间。保持社会距离的措施在10个重点国家之间的效果有所不同。这种差异是由于各国颁布的保持社会距离措施水平不同以及颁布时COVID-19传播情况不同造成的。(C) 2020 Elsevier B.V.版权所有
From the end of 2019, an unprecedented novel coronavirus, which was named COVID-19 by the World Health Organization (WHO) emerged from Wuhan city, China. Despite rigorous global containment and quarantine efforts, the incidence of COVID-19 has continued to rise, with over 4 million confirmed-cases and over 300,000 deaths worldwide until mid-May. This study aims to present the effect of the promulgation of social distancing measures on the spread of COVID-19 in the cases of 10 highly infected countries. The authors focus on the statistics of the COVID-19 confirmed-cases and deaths in 10 highly infected countries, including The US., Spain, Italy, The U.K., France, Germany, Russia, Turkey, Iran and China, and the response to the pandemic of these countries in the period from January 11 to May 2, 2020. The relationships between the social distancing measures and the statistics of COVID-19 confirmed-cases and deaths were analyzed in order to elucidate the effectiveness of the social distancing measures on the spread of COVID-19 in 10 highly infected countries. The results showed it tookl-4 weeks since the highest level of social distancing measures promulgation until the daily confirmed-cases and deaths showed signs of decreasing. The effectiveness of the social distancing measures on the spread of COVID-19 was different between the 10 focused countries. This variation is due to the difference in the levels of promulgated social distancing measures, as well as the difference in the COVID-19 spread situation at the time of promulgation between the countries.
