A former IRL colleague had long covid issues including hospital stays. They posted about it for a stretch on Twitter but generally didn't talk about it, and then almost everyone I know through Twitter dispersed. Then there are a few people who I only know online but their symptoms are more 'months of brain fog' than being stuck at home or catatonic. So there might be more cases in your network where people are just not vocal about it.

Part of the issue is it's unclear what long covid is, if it's the same thing as chronic fatigue syndrome, and who even knows enough about this to be worth listening to
