The one fundamental question at hand is, is it better to get exposed to a lot of people for very short amounts of time or the same set of people for extended amounts of time. I don't know the answer to that - but I think the reason why infections are high in places like restaurants is you are indoor and for more extended period of times and thus it is more likely if someone comes in contact with the virus, they are in contact with it for a bit more extended of a time and therefor more likely to cause infection.qwerty said:irvinehomeowner said:@qwerty: You can't compare a classroom to a grocery store.
Why not? Grocery stores have more people come in than a classroom would have. Adults that are more infectious than elementary aged kids who do not transmit covid at the same levels.
Elementary schools are probably different than middle and high schools in that respect as the older kids seem to transit covid at the same rate as adults. With the older kids though it?s easier for them to wear masks (if mandated). The nba games being announced in the bubble have plexiglass between the announcers. Pretty interesting setup actually.
For elementary schools they could have just cut out all of the bullshit and do two sessions of three hours each. Each kid sits at their desk that has plexiglass around the desks, have the teacher stand behind the plexiglass. Teach three hours and send the kids home. No recess, no lunch. Have the kids eat at home.
You could do a similar set up for middle and high schools. In theory the middle and high schools can be more regimented as the kids are older.
So it is kind of one of those, in a grocery store you see way more people but have a likely lower probability of infection rate. In a school - way less people (assuming schools keep classes small and keep contact within the classes) - but if one person is infected, infection rate much higher.
The reality is - they should have those rapid testing (even if they aren't highly effective) within schools, etc, as a way to tightly monitor everything so that when you have outbreaks - you keep them small and well contained. I.e., lock them down at the source.
