There's also been some cases of transmission in camps (I think Arkansas and Georgia). Yes, those were sleep away camps so kids basically living together. But it's also clear there isn't 0 transmission. Even if we get to reopen the schools (which is LA, OC and Ventura Counties isn't looking too good right now), they are going to get constantly reclosed because some kid catches it from his parents and everyone has to quarantine. We're really at the point where either we just say to hell with it and accept the risks, or we don't (and California seems to be saying we don't). The experts don't want to say that, so they've handed down a bunch of rules which are unworkable and no one can meet, which is why everyone is spinning their wheels, and why t jumped into the fray and the CDC responded by just confusing things even more.
The plans to reopen the Thatcher and Cate boarding schools are interesting. No day schoolers will be allowed. You have to board. Students will be hard shut and isolated on campus until thanksgiving as will a lot of the teachers and admin who are moving on campus. They don't say, though, what happens to the service workers (kitchen workers, cleaning staff, security, horse groomers). At a very minimum they'll be vets coming in and out of the Thatcher to care for the horses so not sure how tight that bubble can be, or if the state will sign off on their plans.
