Good question! I believe this is a duplicate of Will COVID-19 survivors suffer lasting disability at a high rate?
I have gathered some links in: https://www.lesswrong.com/posts/CSKsPwMjn2JxYroNA/how-likely-is-the-covid-19-apocalyptic-scenario?commentId=X554vNDwzpCyZQeFP -but I guess it is dated now. It is strange that we don't have stats about that - it is only one step more difficult than the CFR stats.
I'm in my late twenties. I can easily find estimates of the risk of death, but I'm having trouble figuring out what the risk of permanent injury (e.g. fatigue) is. I figure someone on LW has probably already looked into this, so I thought I'd ask.
