Retrospective contact tracing, enabled by the use of automated visitor-management systems and digital contact tracing, together with rapid antigen detection (RAD) for SARS-CoV-2 among visitors staying ≥ 30 minutes, identified COVID-19 cases in < 0.01% (6/72 605) of hospital visitors to a large hospital campus over an 8-week study period. The potential for nosocomial transmission of SARS-CoV-2 from hospital visitors was thus very low, and could be further mitigated by universal mask-wearing among staff and visitors.
回顾性接触者追踪，通过使用自动化访客管理系统和数字接触者追踪，以及对停留时间≥30 分钟的访客进行 SARS-CoV-2 的快速抗原检测（RAD），在对大型医院园区的 72605 名医院访客进行的 8 周研究期间，发现 COVID-19 病例的比例不到 0.01%（6/72605）。因此，医院访客向医院传播 SARS-CoV-2 的可能性非常低，并且通过工作人员和访客普遍佩戴口罩，可以进一步降低传播风险。
