我们评估了预防严重急性呼吸道疾病冠状病毒2 （SARS-CoV-2）感染的个人防护措施的有效性。我们的病例对照研究包括泰国的211例冠状病毒病（COVID-19）和839例对照。病例定义为与COVID-19患者无症状接触，后来SARS-CoV-2检测呈阳性；对照组是从未检测呈阳性的无症状接触者。与不戴口罩相比，在接触过程中一直戴口罩与感染SARS-CoV-2的风险较低独立相关；有时在接触期间戴口罩并不能降低感染风险。我们发现，佩戴的口罩类型与感染并不独立相关，而且总是戴口罩的接触者更有可能保持社交距离。与COVID-19患者保持10至10米的距离、密切接触时间小于15分钟以及经常洗手与感染风险较低独立相关。我们的研究结果支持持续佩戴口罩、洗手和保持社交距离来预防COVID-19。
We evaluated effectiveness of personal protective measures against severe acute respiratory disease coronavirus 2 (SARS-CoV-2) infection. Our case-control study included 211 cases of coronavirus disease (COVID-19) and 839 controls in Thailand. Cases were defined as asymptomatic contacts of COVID-19 patients who later tested positive for SARS-CoV-2; controls were asymptomatic contacts who never tested positive. Wearing masks all the time during contact was independently associated with lower risk for SARS-CoV-2 infection compared with not wearing masks; wearing a mask sometimes during contact did not lower infection risk. We found the type of mask worn was not independently associated with infection and that contacts who always wore masks were more likely to practice social distancing. Maintaining >1 m distance from a person with COVID-19, having close contact for <15 minutes, and frequent handwashing were independently associated with lower risk for infection. Our findings support consistent wearing of masks, handwashing, and social distancing to protect against COVID-19.
