First of all, the poster you are referring to was me.
If it's a big deal, it can be a big deal we talk about accurately. Safety isn't the only factor needing to be measured here. The death rate isn't relatively low among children. It's extremely low or as I said, infinitesimally low. You don't want to go that far for some reason but the data supports it. If you're a data guy, then go there and be accurate. Relative to children, the flu is far more dangerous than Covid. The data supports that also.
Case counts are something to watch but it is at the bottom of the list of numbers to watch. This variant is going to hit everywhere and everyone. It's hard to overstate how contagious it is. Nothing is going to stop it from spreading. So hospital numbers are where we should be focusing. If there are students with covid, that's OK. How many have serious issues is the question. The answer, again, is probably very few and those kids are probably dealing with other health preconditions that exacerbate the impact of Covid (i.e. they need to watch out for every respiratory illness).
If we "raise the alarm" then what do you want to do? The data illustrates very clearly there is NOTHING you can do to stop this. So what does this alarm set in motion? You're awfully paternalistic for my case. And you seem determined to avoid any and all data so that you can feel justified in your reaction. While it is quite clear you're a good person with a true heart for others, it's also quite clear that big heart of yours is doing the talking in this thread. Please allow the facts and the data to calm you a bit. It's going to be OK!
