There seem to be other nasty long term effects that are mostly unknown.

The idea that kids don't get or spread covid is not supported by evidence. They seem to get less symptoms, but there isn't enough evidence to say they don't get or spread it. Some studies suggest they are more likely to get and spread it, but there isn't enough to make strong statements yet

Of course, there always non zero probably of death for anything.

Of course, it could happen with any other diseases

Of course they may get or spread it but its very unlikely.

>but there isn't enough to make strong statements yet

Exactly, if there isn't enough evidence then don't close school.
