Calculus: Having campus-wide COVID surveillance running (before any alternative testing options had sprung up) is more important than preventing ANY RISK of someone experiencing stigma for having had COVID. I think this calculus holds up and is not that dehumanizing. I'm not saying we should get rid of all protections, but that pendulum is too far on the regulatory side right now.
In that case, just cut out the middle man and start reading their medical records. Who needs privacy?
(... And then people rationally respond to such an invasion by no longer going to the doctors and lying about their medical history...)
We can't interpret people's desire for privacy as damage and route around it. There's decades of history of scientists interacting with the public to show why that has negative consequences for society.
