I'm wondering this as well.
I'm assuming he's in the medical field so he's probably around Covid.
Isn't it possible to be around Covid so much you could have it in your nose but not have Covid? The pcr can pick that up, and you could be suffering from seasonal allergies at the same time.
There are a lot of possibilities here besides reinfection. Even if he does have Covid it sounds like it's not a big deal, I'm just wondering if it isn't something else and a false positive pcr.
