If the kid has symptoms, which is very unlikely, that's when you'd seek treatment. But if the kid has no symptoms, which is far more likely, what would there be to treat?

if the kid has no symptoms, and tests positive, it is a case to self isolate (the kid as well as the whole family) - so they don't transmit it to other kids and teachers who might be vulnerable. And in this case, it might very well be fatal to the teachers who are in close contact with the kid.

Why is this so hard to grasp? Being a disease carrier is a problem even if the kid doesn't show symptoms, especially it's been established that covid is transmissible with no symptoms.

As I said, "Just don't let junior visit grandma."

As far as I understand there is only symptomatic treatment. (apart from remdesivir, but not sure if I would give it a child before it really needs it (worried about sideeffects?))

My understanding is remdesivir is difficult to produce. It hasn't gotten a lot of attention but I wonder about the supply chain for some of these hard-to-manufacture drugs.
