Actually, I think I got it from food.

One of the odd symptoms is that it works like reverse COVID, instead of being contagious weeks before you manifest symptoms you remain contagious for weeks after you’ve recovered symptom wise.

My guess is someone was out of sick days and felt better and passed it on to me when an errant particle of spittle from a sneeze they’d thought they’d covered up gave the little bugger the chance to hop ships.
