After detection of cases of COVID-19 in Florida in March 2020, the governor declared a state of emergency on March 9,* and all school districts in the state suspended in-person instruction by March 20. Most kindergarten through grade 12 (K-12) public and private schools in Florida reopened for in-person learning during August 2020, with varying options for remote learning offered by school districts. During August 10-December 21, 2020, a total of 63,654 COVID-19 cases were reported in school-aged children; an estimated 60% of these cases were not school-related. Fewer than 1% of registered students were identified as having school-related COVID-19 and <11% of K-12 schools reported outbreaks. District incidences among students correlated with the background disease incidence in the county; resumption of in-person education was not associated with a proportionate increase in COVID-19 among school-aged children. Higher rates among students were observed in smaller districts, districts without mandatory mask-use policies, and districts with a lower proportion of students participating in remote learning. These findings highlight the importance of implementing both community-level and school-based strategies to reduce the spread of COVID-19 and suggest that school reopening can be achieved without resulting in widespread illness among students in K-12 school settings.

重新开放的第一学期-佛罗里达州，2020年8月至12月，中小学环境中的COVID-19。

在2020年3月在佛罗里达州发现COVID-19病例后，州长在3月9日*宣布进入紧急状态，并且该州所有学区在3月20日前暂停了亲自指导。大部分幼儿园至12年级（K- 12）佛罗里达州的公立和私立学校于2020年8月重新开放用于面对面学习，学区提供了多种远程学习选项。2020年8月10日至12月21日，学龄儿童报告了63,654例COVID-19病例；估计其中60％与学校无关。不到1％的注册学生被确认患有与学校相关的COVID-19，而报告有暴发事件的K-12学校中，不到11％。学生的地区发病率与该县的背景疾病发病率相关；恢复学历与适龄儿童中COVID-19的相应增加没有关系。在较小的地区，没有强制性口罩使用政策的地区以及参加远程学习的学生比例较低的地区，学生的比率较高。这些发现凸显了实施社区一级和基于学校的策略以减少COVID-19传播的重要性，并建议在K-12学校环境下，在不导致学生普遍生病的情况下实现学校的重新开放。
