儿童中严重的COVID-19很少见，但许多学校仍然关闭，因为学校接触对成人和更广泛社区造成的传播风险尚不清楚。Lessler等人观察到美国学区采取的方法的异质性，利用卡内基梅隆大学和Facebook的COVID-19症状调查数据，研究了不同策略如何影响更广泛社区的COVID-19传播率。作者发现，当缓解措施到位时，学校内的传播是有限的，感染率反映了周围社区的感染率。科学，abh2939，本期p. 1092与实施很少或没有缓解措施的学校有关的学生COVID-19发病率升高。事实证明，在严重急性呼吸系统综合征冠状病毒2 （SARS-CoV-2）大流行期间，面对面教育一直存在争议，而且很难进行研究。美国一项大规模在线调查的数据显示，与亲自上学的孩子一起生活的受访者患covid -19相关疾病的风险增加。以学校为基础的缓解措施与风险的显著降低有关，特别是日常症状筛查、教师屏蔽和关闭课外活动。面对面教育与COVID-19结果之间的正相关关系在低缓解水平下仍然存在，但当报告采取了七项或更多缓解措施时，就不再观察到这种显著关系。在教师中，在家以外工作与covid -19相关结果的增加有关，但这种关联与其他职业（例如医疗保健或办公室工作）中观察到的情况相似。虽然面对面的学校教育与家庭COVID-19风险有关，但通过适当实施以学校为基础的缓解措施，这种风险很可能得到控制。
Severe COVID-19 in children is rare, but many schools remain closed because the transmission risk that school contact poses to adults and the wider community is unknown. Observing the heterogeneity of approaches taken among U.S. school districts, Lessler et al. investigated how different strategies influence COVID-19 transmission rates in the wider community using COVID-19 Symptom Survey data from Carnegie Mellon and Facebook. The authors found that when mitigation measures are in place, transmission within schools is limited and infection rates mirror that of the surrounding community. Science, abh2939, this issue p. 1092 COVID-19 rates were elevated for those connected to schools that implemented few or no mitigation measures. In-person schooling has proved contentious and difficult to study throughout the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. Data from a massive online survey in the United States indicate an increased risk of COVID-19–related outcomes among respondents living with a child attending school in person. School-based mitigation measures are associated with significant reductions in risk, particularly daily symptoms screens, teacher masking, and closure of extracurricular activities. A positive association between in-person schooling and COVID-19 outcomes persists at low levels of mitigation, but when seven or more mitigation measures are reported, a significant relationship is no longer observed. Among teachers, working outside the home was associated with an increase in COVID-19–related outcomes, but this association is similar to that observed in other occupations (e.g., health care or office work). Although in-person schooling is associated with household COVID-19 risk, this risk can likely be controlled with properly implemented school-based mitigation measures.
