Healthcare worker (HCW) infections due to COVID-19 are of serious consequence. Testing for antibodies against COVID-19 in HCWs has been previously recommended. We conducted a serosurvey in HCWs at a private hospital in Mumbai which is treating COVID patients. A total of 244 HCWs were tested. The prevalence of infection in asymptomatic HCWs was 4.3% and in previously symptomatic untested HCWs was 70%. We recommend that HCWs with a previous history of COVID symptoms who were not tested/tested negative by reverse transcription–polymerase chain reaction should be tested for antibodies at least 2 weeks after onset of symptoms.

印度孟买大流行高峰期医护人员中 COVID-19 抗体的流行率：一项初步研究


COVID-19 引起的医护人员 (HCW) 感染后果严重。以前曾建议在医护人员中检测 COVID-19 抗体。我们在孟买一家治疗 COVID 患者的私立医院对医护人员进行了血清学调查。总共测试了 244 名医护人员。无症状 HCW 的感染率为 4.3%，先前有症状且未经检测的 HCW 感染率为 70%。我们建议有 COVID 症状既往病史但未通过逆转录-聚合酶链反应检测/检测为阴性的医护人员应在症状出现后至少 2 周进行抗体检测。
