Relatively few studies have assessed risk factors for coronavirus disease 2019 (COVID-19) in public facilities used by children and adolescents. This study presents an analysis of a COVID-19 outbreak that occurred in a taekwondo gym in Korea, predominantly among children and adolescents, with the aim of providing insights on managing COVID-19 outbreaks in similar facilities.
All 108 taekwondo gym students and staff received COVID-19 tests. A survey and closed-circuit television analyses were used to identify risk factors. A univariate analysis was conducted, followed by multivariate logistic regression analysis with backward elimination for variables with a significance level <0.10 in the univariate analysis.
COVID-19 was confirmed in 30 of 108 subjects at the taekwondo gym (attack rate, 27.8%). The outbreak started in an adult class student. This student transmitted the virus to the staff, who consequently transmitted the virus to adolescent students. In the univariate analysis, the relative risk for younger age (≤9 years) was 2.14 (95% confidence interval [CI], 1.01-4.54; p=0.054), and that for food consumption inside the gym was 2.12 (95% CI, 1.04-4.30; p=0.048). In the multivariate logistic regression analysis, the odds ratio for younger age was 2.96 (95% CI, 1.07-8.20; p=0.036), and that for food consumption inside the gym was 3.00 (95% CI, 1.10-8.17; p=0.032).
Food consumption inside the facility and young age were significant risk factors for COVID-19 transmission in this taekwondo gym. Food consumption should be prohibited in sports facilities, and infection prevention education for young students is also required.
相对较少的研究评估了儿童和青少年使用的公共设施中2019冠状病毒病（COVID-19）的风险因素。本研究对韩国一家跆拳道馆发生的COVID-19疫情进行了分析，该疫情主要发生在儿童和青少年中，旨在为管理类似设施中的COVID-19疫情提供见解。
108名跆拳道馆学生和工作人员均接受了COVID-19检测。通过调查和闭路电视分析来识别风险因素。进行了单因素分析，随后对单因素分析中显著性水平<0.10的变量进行了向后消除的多因素逻辑回归分析。
跆拳道馆108名受试者中有30人确诊感染COVID-19（感染率为27.8%）。疫情始于一名成人班学生。该学生将病毒传播给了工作人员，工作人员随后又将病毒传播给了青少年学生。在单因素分析中，年龄较小（≤9岁）的相对风险为2.14（95%置信区间[CI]，1.01 - 4.54；p = 0.054），在馆内食用食物的相对风险为2.12（95%CI，1.04 - 4.30；p = 0.048）。在多因素逻辑回归分析中，年龄较小的优势比为2.96（95%CI，1.07 - 8.20；p = 0.036），在馆内食用食物的优势比为3.00（95%CI，1.10 - 8.17；p = 0.032）。
在这家跆拳道馆中，在馆内食用食物和年龄较小是COVID-19传播的重要风险因素。体育设施应禁止食用食物，同时也需要对年轻学生进行感染预防教育。
