Glad it is not covid. But total suck you catching some other nasty thing.
I'm glad it's the lesser of 2 evils for you! I can't believe someone contagious with that went out and clearly didn't wash their hands.
I was kinda hoping quarantine would bring an end to the dreaded Noro and Rota.... and at the same time I never thought I'd have the thoughts "please let it be gastro!" For someone.... covid has taken me on emotional roller coaster
So, it probably was Noro, according to my doctor. All the symptoms match and I'm starting to feel better so the recovery time also matches.
Which does mean that some jerk with symptoms or just barely recovering decided to go out and shop. You are most contagious while you have symptoms, followed by right after when you are recovering.
