Abstract

As coronavirus disease 2019 (COVID-19) outbreaks in healthcare facilities are a serious public health concern, we performed a case-control study to investigate the risk of COVID-19 infection in healthcare workers. We collected data on participants' sociodemographic characteristics, contact behaviors, installation status of personal protective equipment, and polymerase chain reaction testing results. We also collected whole blood and assessed seropositivity using the electrochemiluminescence immunoassay and microneutralization assay. In total, 161 (8.5%) of 1,899 participants were seropositive between August 3 and November 13, 2020. Physical contact (adjusted odds ratio 2.4, 95% confidence interval 1.1-5.6) and aerosol-generating procedures (1.9, 1.1-3.2) were associated with seropositivity. Using goggles (0.2, 0.1-0.5) and N95 masks (0.3, 0.1-0.8) had a preventive effect. Seroprevalence was higher in the outbreak ward (18.6%) than in the COVID-19 dedicated ward (1.4%). Results showed certain specific risk behaviors of COVID-19; proper infection prevention practices reduced these risks.

日本医务人员特定COVID-19风险行为及个人防护装备的预防效果

鉴于2019冠状病毒病(COVID-19)在医疗机构中的暴发是一个严重的公共卫生问题，我们开展了一项病例对照研究，以调查医疗工作者感染COVID-19的风险。我们收集了参与者的社会人口学特征、接触行为、个人防护装备的安装状况和聚合酶链反应检测结果。我们还收集了全血，并使用电化学发光免疫测定和微量中和测定评估血清阳性。在2020年8月3日至11月13日期间，1899名参与者中共有161人(8.5%)血清阳性。身体接触(校正优势比为2.4,95%可信区间为1.1-5.6)和气溶胶产生过程(1.9,1.1-3.2)与血清阳性相关。使用护目镜(0.2、0.1 ~ 0.5)和N95口罩(0.3、0.1 ~ 0.8)有预防效果。疫情病房的血清阳性率(18.6%)高于COVID-19专用病房(1.4%)。结果显示有特定的COVID-19危险行为;适当的感染预防措施减少了这些风险。
