论文摘要
这项研究是在2020年5月18日至7月10日在杜克大学（Duke University）的Domath计划中进行的。当时，杜克大学和全国其他大学都在努力解决如何在秋天安全欢迎学生回到校园的问题。因此，我们的项目着重于使用数学模型评估策略来抑制病毒在校园中的传播，特别是在宿舍和教室中。对于宿舍，我们表明，给学生单人间而不是双人间可以大大减少病毒传播。对于教室，我们表明，在线上的尺寸高于某些截止的课程可以使基本的繁殖数字$ r_0 <1 $ <1 $，从而阻止了广泛的流行病。临界值将取决于教室中疾病的传染性。
This research was done during the DOMath program at Duke University from May 18 to July 10, 2020. At the time, Duke and other universities across the country were wrestling with the question of how to safely welcome students back to campus in the Fall. Because of this, our project focused on using mathematical models to evaluate strategies to suppress the spread of the virus on campus, specifically in dorms and in classrooms. For dorms, we show that giving students single rooms rather than double rooms can substantially reduce virus spread. For classrooms, we show that moving classes with size above some cutoff online can make the basic reproduction number $R_0<1$, preventing a wide spread epidemic. The cutoff will depend on the contagiousness of the disease in classrooms.
