Abstract

In this prospective cohort study, 30 health care personnel with a known SARS-CoV-2 exposure provided oropharyngeal swabs for polymerase chain reaction (PCR) testing and blood specimens for serologic testing at 2 time points postexposure. At a median 7 days postexposure (range, 1-13 days), none had a positive PCR and 1 (3%) had a reactive antibody test. No additional participants were PCR or antibody-positive at a median 25 days postexposure (range, 14-36 days).

2020年12月- 2021年12月无症状接触SARS-CoV-2的医护人员的SARS-CoV-2 PCR和抗体阳性分析

在这项前瞻性队列研究中，30名已知暴露于SARS-CoV-2的卫生保健人员在暴露后的两个时间点提供了用于PCR检测的口咽拭子和用于血清学检测的血液标本。在暴露后中位7天（范围1-13天），没有人PCR阳性，1人（3%）有反应性抗体检测。在暴露后中位25天（范围14-36天），没有其他参与者PCR或抗体阳性。
