The occurrence of cases of COVID-19 reported by child care facilities among children, teachers, and staff members is correlated with the level of community spread (1,2). To describe characteristics of COVID-19 cases at child care facilities and facility adherence to guidance and recommendations, the District of Columbia (DC) Department of Health (DC Health) and CDC reviewed COVID-19 case reports associated with child care facilities submitted to DC Health and publicly available data from the DC Office of the State Superintendent of Education (OSSE) during July 1-December 31, 2020. Among 469 licensed child care facilities, 112 (23.9%) submitted 269 reports documenting 316 laboratory-confirmed cases and three additional cases identified through DC Health's contact tracers. Outbreaks associated with child care facilities, defined as two or more laboratory-confirmed and epidemiologically linked cases at a facility within a 14-day period (3), occurred in 27 (5.8%) facilities and accounted for nearly one half (156; 48.9%) of total cases. Among the 319 total cases, 180 (56.4%) were among teachers or staff members. The majority (56.4%) of facilities reported cases to DC Health on the same day that they were notified of a positive test result for SARS-CoV-2, the virus that causes COVID-19, by staff members or parents. Facilities were at increased risk for an outbreak if they had been operating for <3 years, if symptomatic persons sought testing ≥3 days after symptom onset, or if persons with asymptomatic COVID-19 were at the facility. The number of outbreaks associated with child care facilities was limited. Continued implementation and maintenance of multiple prevention strategies, including vaccination, masking, physical distancing, cohorting, screening, and reporting, are important to reduce transmission of SARS-CoV-2 in child care facilities and to facilitate a timely public health response to prevent outbreaks..
儿童、教师和工作人员所在的儿童保育机构报告的 COVID-19 病例的发生与社区传播水平有关(1,2)。为了描述儿童保育机构 COVID-19 病例的特征以及机构对指导和建议的遵守情况，哥伦比亚特区 (DC) 卫生部门 (DC Health) 和疾病预防控制中心审查了与 2020 年 7 月 1 日至 12 月 31 日期间向 DC Health 报告的 COVID-19 病例报告和从 DC 州立教育总监办公室 (OSSE) 获得的公开数据。在 469 家持照儿童保育机构中，有 112 家(23.9%)提交了 269 份报告，记录了 316 例实验室确诊病例和另外 3 例通过 DC Health 接触追踪者确定的病例。与儿童保育机构相关的暴发，定义为在 14 天内一个设施内发生两例或多例实验室确诊且具有流行病学联系的病例(3)，发生在 27 家(5.8%)设施中，占总病例数的近一半(156 例；48.9%)。在 319 例总病例中，有 180 例(56.4%)发生在教师或工作人员中。大多数(56.4%)机构在接到工作人员或家长通知 SARS-CoV-2 阳性检测结果的当天向 DC Health 报告了病例，SARS-CoV-2 是导致 COVID-19 的病毒。如果设施运营时间不足 3 年、有症状的人在症状出现后≥3 天寻求检测，或者无症状的 COVID-19 患者在设施中，设施发生暴发的风险就会增加。与儿童保育机构相关的暴发数量有限。继续实施和维护多种预防策略，包括接种疫苗、戴口罩、保持身体距离、分组、筛查和报告，对于减少儿童保育机构中 SARS-CoV-2 的传播以及及时做出公共卫生响应以防止暴发非常重要。
