Sorry. I guess I clicked on the part that brought me to his thread. It is actually an interesting read BTW. Not sure I think pool testing is the way to go without more information, but it's an interesting idea.
Edit: Anyway, I looked at her thread, the idea that maybe kids can't spread COVID or aren't big spreaders is interesting, but I think we need a lot more research on that and at what age this strange transition to being a non-spreader takes place. Also, I noted that she cites a Reuters article saying that Denmark has not seen a rise because they opened schools. But, I don't think that's actually true. They are seeing a rise is their R rate that coincides with them opening schools and I know they are watching that very closely to see if it's a problem. And, the Danes have pretty much so crushed the virus in their country so it's certainly less of an issue to open schools when there is very little virus around than in the situation the U.S. is in. But, I do agree with her that opening schools should be driven by science. But what is really driven by science in this country anymore?
