评价和比较4种非药物干预措施（npi）控制2019冠状病毒病（COVID-19）时变有效繁殖数（Rt）的有效性。该研究包括2020年1月23日至4月13日期间来自190个国家的1908,197例COVID-19确诊病例。实施的国家行动计划分为四类：公共场所强制佩戴口罩、隔离或检疫、保持社交距离和交通限制（以下分别称为强制佩戴口罩、隔离、保持距离和交通限制）。与未采取相应措施的人群相比，实施强制性口罩、隔离、保持距离和交通与COVID-19 Rt的变化相关（95%置信区间，CI）分别为- 15.14%（从- 21.79%至- 7.93%）、- 11.40%（从- 13.66%至- 9.07%）、- 42.94%（从- 44.24%至- 41.60%）和- 9.26%（从- 11.46%至- 7.01%）。保持距离和同时实施两种或两种以上的npi似乎与COVID-19的Rt的更大下降有关。我们的研究表明，npi可以显著遏制COVID-19大流行。保持距离并同时实施两个或两个以上的国家行动计划应成为遏制COVID-19的战略重点。
To evaluate and compare the effectiveness of four types of non-pharmaceutical interventions (NPIs) to contain the time-varying effective reproduction number (Rt) of coronavirus disease-2019 (COVID-19). This study included 1,908,197 confirmed COVID-19 cases from 190 countries between 23 January and 13 April 2020. The implemented NPIs were categorised into four types: mandatory face mask in public, isolation or quarantine, social distancing and traffic restriction (referred to as mandatory mask, quarantine, distancing and traffic hereafter, respectively). The implementations of mandatory mask, quarantine, distancing and traffic were associated with changes (95% confidence interval, CI) of −15.14% (from −21.79% to −7.93%), −11.40% (from −13.66% to −9.07%), −42.94% (from −44.24% to −41.60%) and −9.26% (from −11.46% to −7.01%) in the Rt of COVID-19 when compared with those without the implementation of the corresponding measures. Distancing and the simultaneous implementation of two or more types of NPIs seemed to be associated with a greater decrease in the Rt of COVID-19. Our study indicates that NPIs can significantly contain the COVID-19 pandemic. Distancing and the simultaneous implementation of two or more NPIs should be the strategic priorities for containing COVID-19.
