SASEA

项目摘要/摘要 除了学术教育之外，学校还扮演着重要的社区角色。在历史上被边缘化的 社区他们是值得信赖的提供者，为有需要的家庭提供一系列支持服务。权衡取舍 在面对面学习对防止SARS-CoV-2在学校传播的风险的这些关键好处之间 在2020年和2021年的大部分时间里，设置一直是人们热议的话题。赌注特别高，在 历史上最严重依赖学校服务的边缘化社区，但也受到了 新冠肺炎最困难的主要原因是结构性问题。更安全的学校早期预警(SASEA)计划是 由加州大学圣地亚哥分校、圣地亚哥县和15所合作学校共同开发 为圣地亚哥县5个学区的社会弱势学生提供服务。SASEA每天都在使用 污水和地面(地面)环境监测以发现无症状的SARS-CoV-2感染 在校园里的学生和教职员工中。积极的环境信号紧随其后的是目标 对整个学校(废水)或教室(表面样本呈阳性)进行响应性测试。 在这个项目中，我们将开发SAFER在学校早期预警学校-邻里资产门户(SASEA- Snap)，这是一个在线学校环境监测报告仪表板，具有解决结构问题的资源 在历史上被边缘化的社区进行新冠肺炎诊断测试的障碍(目标1)。我们还将创建一个 工具包允许任何学校快速调整模板以适应其特定设置。在目标2和目标3中，我们将使用 随机阶梯楔形试验对50所学校SASEA(对照)和SASEA-SNAP(干预)的比较 在圣地亚哥县的4个不同的学校集群。我们的主要成果(目标2)是更高的 干预学校的诊断性测试。我们的次要成果(目标3)是增加风险缓解 学校社区成员在环境监测数据显示存在潜在案例时的行为 校园里。在目标4中，我们将使用40对家长-学生对的亲子叙事访谈来了解 儿童在学校感知新冠肺炎风险，评估对测试障碍的感知差异 干预和控制点，并更好地了解儿童如何理解环境过程 监视和响应性测试。

Project Summary/Abstract Schools serve important community roles beyond academic education. In historically marginalized communities they are trusted providers for a range of support services for families in need. The tradeoff between these crucial benefits of in-person learning against the risk of SARS-CoV-2 transmission in school settings has been hotly debated throughout much of 2020 and 2021. The stakes are particularly high in historically marginalized communities which rely most heavily on school services, but have also been hit the hardest by COVID-19 primarily due to structural issues. The Safer at School Early Alert (SASEA) program was co-developed by the University of California, San Diego, the County of San Diego, and 15 partner schools serving socially vulnerable students in 5 school districts across San Diego County. SASEA utilizes daily wastewater and surface (floor) environmental monitoring to detect asymptomatic SARS-CoV-2 infections among students and staff on campus. Positive environmental signals are immediately followed by targeted responsive testing for a whole school (in the case of wastewater) or classroom (for a positive surface sample). In this project, we will develop the Safer at School Early Alert School-Neighborhood Asset Portal (SASEA- SNAP), an online school environmental monitoring report dashboard with resources to address structural barriers to COVID-19 diagnostic testing in historically marginalized communities (Aim 1). We will also create a toolkit to allow any school to rapidly adapt the template to their specific setting. In Aims 2 and 3, we will use a randomized stepped wedge trial to compare SASEA (control) vs SASEA-SNAP (intervention) in 50 schools across 4 diverse school clusters in San Diego County. Our primary outcome (Aim 2) is higher rates of diagnostic testing in intervention schools. Our secondary outcome (Aim 3) is increased risk mitigation behaviors in school community members when environmental surveillance data suggests a potential case on campus. In Aim 4, we will use parent-child narrative interviews with 40 parent-student pairs to understand how children perceive COVID-19 risk at school, assess differences in perceptions of testing barriers between intervention and control sites, and better understand how children understand the process of environmental surveillance and responsive testing.
