The SARS-CoV‑2 pandemic and the different manifestations of the coronavirus disease 2019 (COVID-19) are a major challenge for health systems worldwide. Medical personnel have a special role in containing the pandemic. The aim of the study was to investigate the SARS-CoV‑2 IgG antibody prevalence in extraclinical personnel depending on their operational area in the fight against the COVID-19 pandemic.
On May 28 and 29, 2020, serum samples were taken from 732 of 1183 employees (61.9%) of the professional fire brigade and aid organizations in the city area and tested for SARS-CoV‑2 IgG antibodies. The employees were divided into four categories according to their type of participation. category 1: decentralized PCR sampling teams, category 2: rescue service, category 3: fire protection, category 4: situation center. Some employees participated in more than one operational area.
SARS-CoV‑2 IgG antibodies were detected in 8 of 732 serum samples. This corresponds to a prevalence of 1.1%. A previous COVID-19 infection was known in 3 employees. In order to make a separate assessment of the other employees possible and to diagnose unknown infections, a corrected collective of 729 employees with 6 SARS-CoV‑2 antibody detection was considered separately. The prevalence in the corrected collective is 0.82%. After subdividing the collective into areas of activity, the prevalence was low (1: 0.77%, 2: 0.9%, 3: 1.00%, 4: 1.58%).
The seroprevalence of SARS-CoV‑2 in the study collective is low at 1.1% and 0.82%, respectively. There is an increased seroprevalence in operational areas with a lower risk of virus exposure in comparison to operational areas with a higher risk.
严重急性呼吸综合征冠状病毒2型（SARS-CoV-2）大流行以及2019冠状病毒病（COVID-19）的不同表现形式是全球卫生系统面临的重大挑战。医务人员在遏制疫情方面发挥着特殊作用。本研究的目的是根据临床外人员在抗击COVID-19疫情中的工作领域，调查其SARS-CoV-2 IgG抗体流行情况。
2020年5月28日和29日，从市区专业消防队和救援组织的1183名员工中的732名（61.9%）采集血清样本，检测SARS-CoV-2 IgG抗体。员工根据参与类型分为四类。第1类：分散式PCR采样小组，第2类：救援服务，第3类：消防，第4类：情况中心。一些员工参与了多个工作领域。
732份血清样本中有8份检测出SARS-CoV-2 IgG抗体。这相当于流行率为1.1%。已知3名员工曾感染COVID-19。为了能够对其他员工进行单独评估并诊断未知感染，对729名员工的校正样本进行单独考虑，其中有6例检测出SARS-CoV-2抗体。校正样本中的流行率为0.82%。将样本按活动领域细分后，流行率较低（第1类：0.77%，第2类：0.9%，第3类：1.00%，第4类：1.58%）。
研究样本中SARS-CoV-2的血清流行率较低，分别为1.1%和0.82%。与病毒暴露风险较高的工作领域相比，病毒暴露风险较低的工作领域血清流行率有所增加。
