摘要

2019冠状病毒病(COVID-19)大流行早期存在职业焦虑,感染防控支持面临挑战。本研究的目的是比较初级和二级卫生保健工作者(HCWs)的流行病学特征及其血清学感染证据。对1916名卫生保健工作者进行了前瞻性观察队列调查,并对他们的血清进行了可检测的严重急性呼吸综合征冠状病毒2 (SARS-CoV-2)核蛋白抗体检测。将初级和二级护理的两个亚队列以及血清阳性和血清阴性联合队列之间的数据集进行比较。抗体状态好奇心高。可检测抗体在初级保健人员中为7%,在二级保健人员中为5%,而在一般社区中为1.7%。不适当的个人防护装备(PPE)在初级保健中更为常见,在认为自己没有适当PPE的卫生保健工作者中,可检测抗体的流行率是其两倍。接触者追踪被认为是不充分的,尽管它在血清阳性队列中更常见,建议适当的优先考虑。体温和症状检查警报以及工作排斥在血清阳性队列中更为普遍。血清阳性率数据支持卫生保健工作者的风险增加,适当的个人防护装备的重要性以及日常体温和症状检查的有效性,特别是在初级保健中。

COVID-19 seroprevalence in primary and secondary healthcare workers (HCWs)
Professional anxiety existed early in the coronavirus disease 2019 (COVID-19) pandemic with challenging infection prevention and control support. The aims of this study were to compare epidemiological features of healthcare workers (HCWs) within primary and secondary care with their serological evidence of infection. A prospective observational cohort of 1,916 HCWs completed a questionnaire, and their sera were assayed for detectable antibody to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleoprotein in the first wave of the pandemic. Datasets were compared between the two sub-cohorts in primary and secondary care and between the combined seropositive and seronegative cohorts. Curiosity of antibody status was high. Detectable antibody was 7% in the primary care and 5% in the secondary care workers at a time of 1.7% in the general community. Inappropriate personal protective equipment (PPE) was more common in primary care, and detectable antibody was twice as prevalent in HCWs who felt they did not have appropriate PPE. Contact tracing was perceived to be inadequate although it was more commonly performed in the seropositive cohort suggesting appropriate prioritisation. Both temperature and symptom checking alerts and work exclusion were significantly more prevalent in the seropositive cohort. The seroprevalence data support increased risk for HCWs, the importance of appropriate PPE and the usefulness of the daily temperature and symptom checks, particularly in primary care.
