了解严重急性呼吸道综合征冠状病毒2（SARS-CoV-2）在何处以及如何传播至关重要。病例报告来自中国320个地级市（不包括湖北省）的地方卫生委员会。我们确定了所有涉及三个或三个以上病例的疫情，并审查了报告疫情的封闭空间的主要特征及其相关的室内环境因素。在120个都道府县城市共发现了318起有3例或3例以上病例的疫情，包括1245例确诊病例。在已确定的暴发中，53.8%涉及3例，26.4%涉及4例，只有1.6%涉及10例或更多病例。以家庭为基础的暴发是主要类别（318起暴发中的254起; 79.9%），其次是以交通为基础的暴发（108起; 34.0%），许多暴发发生在一个以上的场所类别。所有确定的三例或三例以上病例的暴发都发生在室内环境中，这证实与一名或多名感染者共用室内空间是SARS-CoV-2感染的主要风险。
It is essential to understand where and how severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is transmitted. Case reports were extracted from the local Municipal Health Commissions of 320 prefectural municipalities in China (not including Hubei Province). We identified all outbreaks involving three or more cases and reviewed the major characteristics of the enclosed spaces in which the outbreaks were reported and their associated indoor environmental aspects. Three hundred and eighteen outbreaks with three or more cases were identified, comprising a total of 1245 confirmed cases in 120 prefectural cities. Among the identified outbreaks, 53.8% involved three cases, 26.4% involved four cases, and only 1.6% involved ten or more cases. Home-based outbreaks were the dominant category (254 of 318 outbreaks; 79.9%), followed by transport-based outbreaks (108; 34.0%), and many outbreaks occurred in more than one category of venue. All identified outbreaks of three or more cases occurred in indoor environments, which confirm that sharing indoor spaces with one or more infected persons is a major SARS-CoV-2 infection risk.
