As the number of Coronavirus Disease (2019) (COVID-19) cases increase globally, countries are taking more aggressive preventive measures against this pandemic. Transmission routes of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) include droplet and contact transmissions. There are also evidence of transmission through aerosol generating procedures (AGP) in specific circumstances and settings. Institutionalized populations without mobility and living in close proximity with unavoidable contact are especially vulnerable to higher risks of COVID-19 infection, such as the elderly in nursing homes, children in orphanages, and inmates in prisons. In these places, higher prevention and control measures are needed. In this study, we proposed prevention and control strategies for these facilities and provided practical guidance for general measures, health management, personal protection measures, and prevention measures in nursing homes, orphanages, and prisons, respectively.

随着全球冠状病毒疾病（2019）（COVID-19）病例数量的增加，各国正在采取更加积极的预防措施来预防这种大流行。严重急性呼吸系统综合症冠状病毒2（SARS-CoV-2）的传播途径包括飞沫和接触传播。在特定情况和环境下，也有通过气溶胶产生程序（AGP）传播的证据。那些没有流动能力并且生活在不可避免的接触中的，制度化的人群特别容易受到COVID-19感染的更高风险，例如养老院中的老年人，孤儿院中的儿童以及监狱中的囚犯。在这些地方，需要采取更高的预防和控制措施。在这个研究中，
