许多国家在大流行期间关闭了学校，以遏制SARS-CoV-2的传播。瑞典关闭了高中，但初中仍然开放，以便对学校关闭情况进行评估。本研究通过比较暴露于和未暴露于开放学校的群体，分析了学校关闭对SARS-CoV-2传播的影响。我们发现，接触开放式学校导致父母感染率略有增加。在教师中，感染率翻了一番，感染蔓延到他们的伙伴。这表明，保持初中开放对SARS-CoV-2在社会中的整体传播影响较小。然而，教师受到影响，可以考虑采取措施保护他们。为了减少严重急性呼吸道综合征冠状病毒2（SARS-CoV-2）的传播，大多数国家关闭了学校，尽管不确定关闭学校是否是一种有效的遏制措施。在大流行开始时，瑞典高中转向在线教学，而初中仍然开放。这样就可以比较在开放式和封闭式学校中所受影响不同、但在其他方面面临类似条件的家长和教师。利用丰富的瑞典注册数据，我们将瑞典的所有学生和教师与他们的家人联系起来，并研究转向在线教学对SARS-CoV-2和COVID-19发病率的影响。我们发现，在家长中，暴露于开放而不是封闭的学校导致PCR证实的感染略有增加（比值比[OR] 1.17; 95%CI [CI 95] 1.03至1.32）。在初中教师中，感染率是高中教师的两倍（OR 2.01; CI 95 1.52至2.67）。这种情况蔓延到初中教师的伴侣，他们的感染率高于高中教师（OR 1.29; CI 95 1.00至1.67）。当分析来自医疗保健访问的COVID-19诊断和严重健康结果的发生率时，教师的结果相似，但父母和教师的合作伙伴的结果较弱。对家长的研究结果表明，保持初中学校开放对SARS-CoV-2在社会中的总体传播影响较小。对教师的调查结果表明，可以考虑采取措施保护教师。
Many countries closed schools during the pandemic to contain the spread of SARS-CoV-2. Sweden closed upper-secondary schools, while lower-secondary schools remained open, allowing for an evaluation of school closures. This study analyzes the impact of school closures on the spread of SARS-CoV-2 by comparing groups exposed and not exposed to open schools. We find that exposure to open schools resulted in a small increase in infections among parents. Among teachers, the infection rate doubled, and infections spilled over to their partners. This suggests that keeping lower-secondary schools open had a minor impact on the overall spread of SARS-CoV-2 in society. However, teachers are affected, and measures to protect them could be considered. To reduce the transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), most countries closed schools, despite uncertainty if school closures are an effective containment measure. At the onset of the pandemic, Swedish upper-secondary schools moved to online instruction, while lower-secondary schools remained open. This allows for a comparison of parents and teachers differently exposed to open and closed schools, but otherwise facing similar conditions. Leveraging rich Swedish register data, we connect all students and teachers in Sweden to their families and study the impact of moving to online instruction on the incidence of SARS-CoV-2 and COVID-19. We find that, among parents, exposure to open rather than closed schools resulted in a small increase in PCR-confirmed infections (odds ratio [OR] 1.17; 95% CI [CI95] 1.03 to 1.32). Among lower-secondary teachers, the infection rate doubled relative to upper-secondary teachers (OR 2.01; CI95 1.52 to 2.67). This spilled over to the partners of lower-secondary teachers, who had a higher infection rate than their upper-secondary counterparts (OR 1.29; CI95 1.00 to 1.67). When analyzing COVID-19 diagnoses from healthcare visits and the incidence of severe health outcomes, results are similar for teachers, but weaker for parents and teachers’ partners. The results for parents indicate that keeping lower-secondary schools open had minor consequences for the overall transmission of SARS-CoV-2 in society. The results for teachers suggest that measures to protect teachers could be considered.
