The big 2024 National Academies consensus paper says that they see similar long term damage from chronic fatigue syndrome and several rare diseases, but don't mention this as an outcome from more common viruses.[1] (Skip ahead to the summary).

The big open question is cumulative damage from multiple COVID-19 infections.[2] There are now many people who have had COVID more than once. (US: 60% at least once, maybe 11% more than once.) A few people have had it many more times, but that seems to involve some pre-existing condition. A VA study of older veterans indicates that cumulative damage is real in older adults. As time goes on, there will be more previously healthy people who have had COVID multiple times, and this question will be answered the hard way.
