The goal all along has been to minimize those of high risk in order to ensure enough hospital capacity/ventilators/etc... I feel like any stats around college campuses should focus on these factors and not simply the number of cases. I know of at least 10 people from my work or family/friend circles that have tested positive, and almost all did not even realize they had it. If most people are able to recover on their own, we should not be making decisions simply on the number or percent of positive cases but rather the original goal of hospital/equipment capacity.
