  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.
