People over ~50 have a ~50% chance of not showing symptoms, under 50 is ~10%. I wonder if there was a flu/cold epidemic 50 years ago that is causing the difference?
I know that some flus have different effects depending on age group due to cohort exposure decades ago.
Though it is a preprint, so could be all sorts of sampling reasons for that outcome.
