We aimed to compare the prevalence of asymptomatic coronavirus disease 19 (COVID-19) among clinical staff in designated COVID-19 units versus that among staff in similar units with no known or suspected COVID-19 patients.
We conducted a cross-sectional survey of healthcare workers (HCWs) in eight Israeli general hospitals. The survey involved a questionnaire and a PCR test for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We surveyed HCWs in COVID-19 units and comparison units (internal medicine and cardiology) between 30th April and 7th May 2020.
There were 522 participants: 291 from COVID-19 units and 231 from comparison units. Only one participant (0.2%, 95%CI: 0.005-1.1%)-an asymptomatic nurse on a COVID-19 unit-tested positive for SARS-CoV-2. In participating COVID-19 units there were two symptomatic HCWs with confirmed COVID-19 in the 2 weeks before the survey; both were infected by contact with a co-worker outside of the COVID-19 unit.
The low prevalence of asymptomatic COVID-19 among HCWs, coupled with an absence of symptomatic COVID-19 acquired during patient care, suggest that Israel's national guidelines for personal protective equipment, which are consistent with those of the World Health Organization, adequately protect HCWs.
我们旨在比较在指定的 2019 冠状病毒病（COVID-19）单位工作的临床医务人员与在无已知或疑似 COVID-19 患者的类似单位工作的医务人员中无症状 COVID-19 的患病率。
我们对以色列 8 家综合医院的医护人员（HCWs）进行了横断面调查。该调查涉及问卷调查和严重急性呼吸综合征冠状病毒 2（SARS-CoV-2）的 PCR 检测。我们于 2020 年 4 月 30 日至 5 月 7 日期间在 COVID-19 单位和对照单位（内科和心脏病学）中调查 HCWs。
共有 522 名参与者：291 名来自 COVID-19 单位，231 名来自对照单位。只有 1 名参与者（0.2%，95%CI：0.005-1.1%）——一名无症状的 COVID-19 病房护士——SARS-CoV-2 检测呈阳性。在参与的 COVID-19 单位中，有 2 名有症状的 HCWs 在调查前 2 周内确诊 COVID-19；两者均因与 COVID-19 病房外的同事接触而感染。
HCWs 中无症状 COVID-19 的低患病率，加上在患者护理期间未出现有症状的 COVID-19，表明以色列的个人防护设备国家指南与世界卫生组织的指南一致，充分保护了 HCWs。
