UW (and other B1G schools, from reports of parents with kids there) has been a bit over the top on testing and quarantine.
Kids living on campus were tested every other week for the first couple weeks, then every week. In the Spring they're going to twice a week.
Covid-positive kids are quarantined, but so are kids they've come in contact with. If you are determined to have been a close contact you are sent to a hotel for two weeks. Meals are brought to your door, and you are not allowed to step outside the room for any reason.
The justification for this is that they don't want spread, and despite very limited negative consequences for kids, they don't want spread into the larger community.
Ironic because the campus' positivity is far lower than that in the community. Virus gonna virus.
