yup! that is my guess honestly. Not an epidemiologist but surrounded by them. Everything is about added probabilities...every student that travels interacts with an increased number of people, their probability goes up. there are thousands of students in the same general area, their probabilities go up. The staff (e.g., dining staff) and faculty come from the local areas, probabilities go up. If one student brings it, they are then in unavoidably tight spaces with other students and faculty...probability of transmission goes up. If I were asked, I would model transmission at a university closer to an aircraft carrier than a city.
