Hubei province in China has completed cycle of quarantine-resumption in 23rd Janauary and 8th April 2020, providing a unique opportunity as for now to assess its intervention impact and the pattern of SARS-COV-2 transmission during the quarantine period. In this study, we evaluate the impact of the metropolitan-wide quarantine on the trend and transmission route of the COVID-19 epidemic in Hubei, China. The intervention reduces more than 70% of new infections in both households and the public space, as well as the deaths caused by COVID-19 pneumonia. Household transmission is the dominant route of disease spread regardless of quarantine. This will provide important evidence and scientific insights to other worldwide countries that are currently under quarantine.
中国湖北省已于 2020 年 1 月 23 日和 4 月 8 日完成隔离-复工期，为评估其干预措施的影响以及隔离期间 SARS-CoV-2 传播模式提供了独特的机会。在这项研究中，我们评估了全市范围的隔离措施对中国湖北省 COVID-19 疫情趋势和传播途径的影响。该干预措施使家庭和公共空间内的新感染病例减少了 70%以上，还降低了 COVID-19 肺炎导致的死亡人数。家庭传播是疾病传播的主要途径，无论是否隔离都是如此。这将为目前正在隔离的其他国家提供重要的证据和科学见解。
