For some schools it might be possible to have full in-person classes safely. I think Caltech could do it, and maybe MIT. Maybe Harvey Mudd, too. Oh, and probably the US military academies. Here's how I imagine it could work at Caltech. 1. For undergraduates, give everyone a rapid response COVID test when they arrive. Anyone who fails is quarantined until they are no longer infectious. 2. Once an undergraduate is clea…
The university is doing 1), as well as 2) to an extent by cancelling spring break.
Interestingly, they haven't opted to do pre-arrival testing giving the following justification:
> Based on the lessons we learned last fall, we expect students’ highest risk activities prior to returning to campus are likely to be traveling to campus and engaging in social activities before classes begin, so efforts will focus on arrival testing and a shelter in place protocol.
We will however have biweekly covid testing throughout the sem, which should be quite effective I think. For Fall, it was only weekly, which meant someone who got infected right after their test would not know until a week later.
