A school district in Northern Ohio implemented a COVID-19 surveillance program from January 4 to May 21, 2021, as in-person school and extracurricular activities resumed.
Among 560 staff members and >6300 students, random weekly testing was performed on 563 students and weekly for 204 students participating in extracurricular activities, and 553 staff.
Cases of COVID-19 were identified among 26 staff members and 23 students. Most of those infected were participating in extracurricular activities (14/23) and in the age range of 14-18. Percent positivity was low (range 0.2-2.4%) throughout the school surveillance program despite significant changes in positivity rate (2.8-19.8%).
This demonstrates that in a setting employing basic yet consistent mitigation strategies, there is low transmission among young children and adolescents as they return to in-person classes and activities. Maintaining layered prevention strategies implemented and sustained with fidelity can substantially limit transmission within schools.
俄亥俄州北部的一个学区于 2021 年 1 月 4 日至 5 月 21 日实施了 COVID-19 监测计划，此时学校恢复了面授课程和课外活动。
在 560 名教职员工和 6300 多名学生中，对 563 名学生进行了随机的每周检测，对 204 名参加课外活动的学生和 553 名教职员工进行了每周检测。
在 26 名教职员工和 23 名学生中发现了 COVID-19 病例。大多数感染者都在参加课外活动（23 人中的 14 人），年龄在 14-18 岁之间。尽管阳性率有显著变化（2.8%-19.8%），但整个学校监测计划中的阳性率很低（范围为 0.2%-2.4%）。
这表明，在采用基本但一致的缓解策略的环境中，当儿童和青少年重返面授课程和活动时，他们之间的传播率很低。通过忠实执行和维持分层预防策略，可以大大限制学校内的传播。
