摘要:

在COVID-19大流行期间,安全实施线下室内授课是全美大学的高度优先事项。为支持大学的这项工作,我们开发了一个数学模型,用于估算大学教室内SARS-CoV-2传播的风险。该模型用于评估大流行期间大学教室中可行干预措施的组合,并优化干预措施集,以允许更高的占用率,与疫情前的线下课程数量相匹配。重要的是,我们确定在座位不受限制的密集教室中,要求超过90%的学生接种疫苗并佩戴口罩,这易于实施,几乎没有后勤或财务成本,并允许课程满负荷进行。学期末的回顾性分析证实了模型的评估,即拟议的教室配置是安全的。我们的框架具有普适性,并用于支持Stanford University的重新开放决策。此外,我们的框架很灵活,适用于广泛的室内环境。它被重新用于大型大学活动和聚会,并可用于支持规划室内空间使用,以避免各个行业(从中学到电影院和餐厅)传播传染病。

英文摘要:

During the COVID-19 pandemic, safely implementing in-person indoor instruction was a high priority for universities nationwide. To support this effort at the University, we developed a mathematical model for estimating the risk of SARS-CoV-2 transmission in university classrooms. This model was used to evaluate combinations of feasible interventions for classrooms at the University during the pandemic and optimize the set of interventions that would allow higher occupancy levels, matching the pre-pandemic numbers of in-person courses. Importantly, we determined that requiring masking in dense classrooms with unrestricted seating with more than 90% of students vaccinated was easy to implement, incurred little logistical or financial cost, and allowed classes to be held at full capacity. A retrospective analysis at the end of the semester confirmed the model's assessment that the proposed classroom configuration would be safe. Our framework is generalizable and was used to support reopening decisions at Stanford University. In addition, our framework is flexible and applies to a wide range of indoor settings. It was repurposed for large university events and gatherings and could be used to support planning indoor space use to avoid transmission of infectious diseases across various industries, from secondary schools to movie theaters and restaurants.
