Infection with SARS- CoV- 2 in health care workers (HCWs) challenges employee health services.
We analyzed telephone Coronavirus Disease 2019 (COVID-19) hotline data over 8 weeks in 2021 during SARS- CoV- 2 Delta variant surge. We calculated COVID-19 case rates among persons-under-investigation (PUIs) for illness at two health care centers (HCs).
There were 41 COVID-19 cases among the 285 PUIs (14.4%) at the study HC and 549 (16.9%) of 3244 at the comparison HC. At the study HC, 11.7% of vaccinated PUIs versus 36.6% of unvaccinated PUIs were COVID-19 positive. The COVID-19 positivity rates among vaccinated and unvaccinated PUIs at the comparison HC were 16.1% and 33.3%, respectively.
In the SARS-CoV-2 Delta variant surge, COVID-19 test positivity rates among unvaccinated symptomatic HCWs are dramatically elevated. Aggressive testing of HCW PUIs is particularly critical during periods of disease upsurge.
SARS-CoV-2 感染医护人员（HCWs）对员工健康服务构成挑战。
我们分析了 2021 年 SARS-CoV-2 Delta 变体激增期间 8 周内的电话冠状病毒病 2019（COVID-19）热线数据。我们计算了在两个医疗中心（HC）中，对患病的待调查者（PUIs）的 COVID-19 病例发生率。
在研究 HC 的 285 名 PUI 中有 41 名 COVID-19 病例（14.4%），而在对照 HC 的 3244 名 PUI 中有 549 名（16.9%）。在研究 HC，接种疫苗的 PUI 中有 11.7%呈 COVID-19 阳性，而未接种疫苗的 PUI 中有 36.6%呈 COVID-19 阳性。在对照 HC，接种疫苗和未接种疫苗的 PUI 的 COVID-19 阳性率分别为 16.1%和 33.3%。
在 SARS-CoV-2 Delta 变体激增期间，未接种疫苗的有症状 HCWs 的 COVID-19 检测阳性率显著升高。在疾病爆发期间，对 HCW PUI 的积极检测尤为关键。
