Not sure why you're being downvoted, yes it's an anecdotal, but it's also something that can't be explained other than "we don't know what long term effects are". If you said "my 20 year old nephew got covid and died and he was healthy", then sure, that's an annecdote of a rare event.

The general view now seems to be "it only affects over 55s", and that's mostly true -- there's lots of data to show that kids particularly are far more at risk of dying from other every day activities.

We have a rough idea of the IFR of 40 year old fit men, or 20 year old obese women, or of 7 year olds and 70 year olds. There's little long term studies for a disease that was identified less than a year ago - at least that I'm aware of.
