Try and add up known cases of children dying. I have been looking and I don’t actually see any support for the often quoted 0.2% fatality risk. In China people under 20 made 2.1% of known Coronavirus cases, but they represent a vastly larger share of the population. Italy and South Korea show mortality by age but zero deaths under 30.

I would now say that as “essentially immune,” but it does support them being at 1/100th the risk of 80+ year olds.

Further it also means shutting down schools early is extremely important. A largely asymptotic population in close contact with each other for hours a day is a nightmare for disease transmission.

So, no, they are not identical.

And from context you can also tell he's talking about otherwise healthy kids -- the "essentially" part of the actual quote.
