我们描述了韩国呼叫中心爆发的冠状病毒病（COVID-19）的流行病学。我们通过使用标准化的流行病学调查表获得人口统计学特征的信息。我们进行了描述性分析，并将结果报告为分类变量的频率和比例。在接受COVID-19检测的1，143人中，共有97人（8.5%，95%CI 7.0%-10.3%）确诊病例。其中，94人在11楼的呼叫中心工作，有216名员工，攻击率为43.5%（95%CI 36.9%-50.4%）。在有症状的病例-患者中，家庭继发发病率为16.2%（95%CI 11.6%-22.0%）。在97名确诊的COVID-19患者中，只有4人（1. 9%）在隔离14天内保持无症状，其家庭接触者中没有人获得继发感染。广泛的接触者追踪、对所有接触者进行检测和早期隔离阻止了进一步的传播，可能有效地控制了拥挤工作环境中的快速疫情。
We describe the epidemiology of a coronavirus disease (COVID-19) outbreak in a call center in South Korea. We obtained information on demographic characteristics by using standardized epidemiologic investigation forms. We performed descriptive analyses and reported the results as frequencies and proportions for categoric variables. Of 1,143 persons who were tested for COVID-19, a total of 97 (8.5%, 95% CI 7.0%-10.3%) had confirmed cases. Of these, 94 were working in an 11th-floor call center with 216 employees, translating to an attack rate of 43.5% (95% CI 36.9%-50.4%). The household secondary attack rate among symptomatic case-patients was 16.2% (95% CI 11.6%-22.0%). Of the 97 persons with confirmed COVID-19, only 4 (1.9%) remained asymptomatic within 14 days of quarantine, and none of their household contacts acquired secondary infections. Extensive contact tracing, testing all contacts, and early quarantine blocked further transmission and might be effective for containing rapid outbreaks in crowded work settings.
