From January to September 2020, we conducted contact-tracing for confirmed coronavirus disease 2019 (COVID-19) patients who visited our outpatient clinic to evaluate the risk of COVID-19 transmission from infected patients to healthcare workers (HCWs). COVID-19 was diagnosed in 8 outpatients. Per the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) polymerase chain reaction test results, none of the 317 HCWs who came in contact had a confirmed COVID-19 diagnosis (0.00%; 95% confidence interval, 0.00%-0.01%). This low rate of transmission from infected outpatients to HCWs suggests that standard precaution such as using surgical mask and hand hygiene protects HCWs from SARS-CoV-2 in a low-risk, outpatient clinic setting.
2020 年 1 月至 9 月，我们对前来我院门诊就诊的确诊的 2019 年冠状病毒病（COVID-19）患者进行了接触者追踪，以评估感染患者向医护人员（HCWs）传播 COVID-19 的风险。在 8 名门诊患者中诊断出 COVID-19。根据严重急性呼吸综合征冠状病毒 2（SARS-CoV-2）聚合酶链反应检测结果，317 名接触者中无 1 例确诊 COVID-19（0.00%；95%置信区间，0.00%-0.01%）。从感染的门诊患者到 HCWs 的这种低传播率表明，在低风险的门诊环境中，标准预防措施（如使用外科口罩和手部卫生）可保护 HCWs 免受 SARS-CoV-2 的侵害。
