Beside the discussable mortality rate among healthy adults, and beside surving with permanent lung damage, many people who are 30-40 have kids who are 0-10. Things take a whole new dimension there.
Coronavirus isn't like the flu in this regard, and is actually less severe the younger you are, including children.
No one under 10 has died from it, and only one person under 20. The mortality rate for people under 50 is about .2% (compared to 2.3% for all cases).
So far it's basically a logarithmic function of age.
The lung damage piece is obviously frightening, and we obviously still have a lot to learn about it as we're not sure why children are able to fend it off so easily yet.
The mortality rate of kids 0-10 has been extremely low.
As for permanent lung damage, it's hard to say. From what I've read about ARDS, as expected, if you're young, lung function and general physical function can improve back close to baseline over time (e.g. 5 years). So it's not like you're going to be confined to a rocking chair but you won't be winning any marathons either.
ARDS is not permanent lung damage. You may recover lung function after ARDS. You will not recover from permanent lung damage. It will even deteriorate and your prognosis is less than 5 years to live. Stratification is a red herring, but feel free to do so.
