2019年12月，中国武汉首次报告了新型冠状病毒病（COVID-19）病例。在本报告中，我们描述了与患者暴露无关的卫生保健工作者（HCWs）中发生的3例COVID-19感染聚集，以及为制止癌症中心持续暴露和传播而采取的干预措施。聚集性病例定义为在同一单位区域内同时工作的卫生保健人员中出现2例或2例以上严重急性呼吸道冠状病毒2 （SARS-CoV-2）阳性COVID-19病例。实时逆转录聚合酶链反应检测确诊病例。对2020年3月1日至4月30日期间的3例聚集性病例进行了接触者追踪、设施观察和感染预防评估，随后实施了控制战略。最初的聚集性病例涉及一个辅助服务部门的医护人员，接触者可追溯到休息室的一次聚会，当时有1名员工出现症状，但尚未被诊断出患有COVID-19，随后传染给了7名员工。第二个集群涉及4名员工，与社区有关。第三个集群只涉及两名可能在同一办公室同时工作的员工。为控制感染在员工之间的传播，采取了加强措施，包括普遍戴口罩、加强清洁、提高意识和监测检测。未发生院内传播。据我们所知，这是癌症医院医护人员中首次出现以医院为基础的COVID-19聚集性感染报告，描述了我们为减轻进一步传播所采取的措施。
Cases of novel coronavirus disease 2019 (COVID-19) were first reported in Wuhan, China, in December 2019. In this report, we describe 3 clusters of COVID-19 infections among healthcare workers (HCWs), not associated with patient exposure, and the interventions undertaken to halt ongoing exposure and transmission at our cancer center. A cluster of cases was defined as 2 or more cases of severe acute respiratory coronavirus virus 2 (SARS-CoV-2)–positive COVID-19 among HCWs who work in the same unit area at the same time. Cases were identified by real-time reverse transcription polymerase chain reaction testing. Contact tracing, facility observations, and infection prevention assessments were performed to investigate the 3 clusters between March 1 and April 30, 2020, with subsequent implementation of containment strategies. The initial cluster involved HCWs from an ancillary services unit, with contacts traced back to a gathering in a break room in which 1 employee was symptomatic, although not yet diagnosed with COVID-19, with subsequent transmission to 7 employees. The second cluster involved 4 employees and was community related. The third cluster involved only 2 employees with possible transmission while working in the same office at the same time. A step-up approach was implemented to control the spread of infection among employees, including universal masking, enhanced cleaning, increase awareness, and surveillance testing. No nosocomial transmission to patients transpired. To our knowledge, this is the first report of a hospital-based cluster of COVID-19 infections among HCWs in a cancer hospital describing our steps to mitigate further transmission.
