当严重急性呼吸综合征冠状病毒 2 (SARS-CoV-2) 大流行开始时，专家们对在社区传播高水平的情况下进行面对面指导表示担忧。我们描述了冬季高峰期间北卡罗来纳州 (NC) K-12 学区内 SARS-CoV-2 的二次传播，以确定缓解策略是否可以阻止校内传播。从 2020 年 10 月 26 日至 2021 年 2 月 28 日，参与 ABC 科学合作的 13 个北卡罗来纳州学区开放接受面对面教学，遵守基本缓解策略，并跟踪社区和学校获得的 SARS-CoV-2 病例。公共卫生官员对每个病例进行了裁决。我们将这些数据与 2020 年 8 月的数据结合起来，评估 SARS-CoV-2 冬季激增对感染率以及每周社区和学校感染病例的影响。我们评估了每个原发病例产生的继发病例数量，以及体育活动在学校获得性病例中的作用。来自13个学区的超过10万名学生和教职员工亲自到校上课；其中，通过分子检测记录了 4,969 例社区获得性 SARS-CoV-2 感染。通过接触者追踪，北卡罗来纳州当地卫生部门工作人员在超过 26,000 名学校密切接触者中发现了另外 209 例感染（二次发病率 <1%）。高中的大多数校内传播（75%）与学校赞助的体育运动有关。激增期间学校感染病例略有增加；然而，从激增前到激增，校内传播率保持稳定，每 20 例原发病例中大约有 1 例是学校获得性病例。只要坚持基本的缓解策略，即使在社区感染激增期间，SARS-CoV-2 在学校内的传播也可以被阻断。在北卡罗来纳州 2020-2021 年冬季 SARS-CoV-2 激增期间，在实施基本缓解策略的学区中，K-12 校内传播率仍然极低。
When the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic began, experts raised concerns about in-person instruction in the setting of high levels of community transmission. We describe secondary transmission of SARS-CoV-2 within North Carolina (NC) K-12 school districts during a winter surge to determine if mitigation strategies can hinder within-school transmission. From 10/26/2020–02/28/2021, 13 NC school districts participating in the ABC Science Collaborative were open for in-person instruction, adhered to basic mitigation strategies, and tracked community- and school-acquired SARS-CoV-2 cases. Public health officials adjudicated each case. We combined these data with that from August 2020 to evaluate the effect of the SARS-CoV-2 winter surge on infection rates, as well as weekly community- and school-acquired cases. We evaluated the number of secondary cases generated by each primary case, as well as the role of athletic activities in school-acquired cases. More than 100,000 students and staff from 13 school districts attended school in-person; of these, 4,969 community-acquired SARS-CoV-2 infections were documented by molecular testing. Through contact tracing, NC local health department staff identified an additional 209 infections among >26,000 school close contacts (secondary attack rate <1%). Most within-school transmissions in high schools (75%) were linked to school-sponsored sports. School-acquired cases slightly increased during the surge; however, within-school transmission rates remained constant, from pre-surge to surge, with approximately 1 school-acquired case for every 20 primary cases. With adherence to basic mitigation strategies, within-school transmission of SARS-CoV-2 can be interrupted, even during a surge of community infections. During the 2020–2021 winter surge of SARS-CoV-2 in North Carolina, K–12 within-school transmission remained extremely low among districts implementing basic mitigation strategies.
