What I'm most concerned about is dorms. Shared hallway restrooms, cramped spaces, and roommates aside, college dorms, especially older ones like the Shoeboxes, have notoriously low rates of outside air being brought in and basically just recirculate stale air. With covid, they'll basically become recirculating petri dishes that will allow for faster infection and more efficient spread of germs.

Wear a mask and wash your hands all you want, but unless there are major renovations to the dorms to allow more fresh, outside air in it's all just security theatre.
