Yep but to be fair that isn’t a younger age group. Broadly speaking under-20s are pretty much unaffected. 20-40 aren’t particularly affected either if in good health and without comorbidities. 40+ can be quite seriously affected and over 65s it’s a double digit risk of death. It’s super non-linear.

It seems speculatively like this is due to age-linked expression of ACE2.
