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.

事实证明，在严重急性呼吸综合征冠状病毒 2 (SARS-CoV-2) 大流行期间，面对面教学存在争议且难以研究。美国一项大规模在线调查的数据表明，与亲自上学的孩子同住的受访者中，出现与 COVID-19 相关的结果的风险增加。以学校为基础的缓解措施与风险的显着降低相关，特别是日常症状筛查、教师佩戴口罩和关闭课外活动。在低缓解水平下，面对面学校教育与 COVID-19 结果之间仍然存在正相关关系，但当报告了七种或更多缓解措施时，就不再观察到显着关系。在教师中，外出工作与 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）中观察到的关联相似。尽管面对面上学与家庭 COVID-19 风险相关，但通过适当实施基于学校的缓解措施，这种风险很可能得到控制。
