Even ignoring deaths, "long COVID" is still a very real unknown: https://news.harvard.edu/gazette/story/2021/04/harvard-medic... As I understand, we don't know much about whether omicron has worse, same, or better outcomes in relation to long-term consequences and persistent symptoms. Pls do share if you've heard otherwise
The Epstein-Barr virus for example can make you tired for months or years.
I am not saying long Covid isn't a thing, but it is not 'special' in any way.
Virus infections can cause damage. Years ago I had an infection that damaged a nerve. So virus infections can leave marks. But most of the time, as with Covid, you will recover from it.
