Perhaps, there is a running theory that Covid activates latent Epstein-Barr Virus among other things. But as far as I know it’s just a glorified hypothesis with little scientific evidence to support it.
I wouldn’t even classify the actual covid episode I had as severe (and indeed, as far as I could tell from reading reports there doesn’t seem to be strong correlation between severity of illness and whether someone gets long covid or for how long). It was not bad enough to go to the hospital (though I did consider doing so a couple of times).
I don’t really get allergies or otherwise and consider myself to have a pretty normal immune system. I get sick at about the same rate as what you would expect a normal person to get sick. My health simply took a v shaped nosedive on a graph for 6 months after I got covid.
