Re: Does this sound like an SV or not?
It's hard to say. All viruses are different and everyone reacts differently to them. Does he have any other lingering symptoms, such as tiredness, body aches, chills, etc.? It could have been something he'd eaten. I'd say it's fine to go home as long as you're careful around the house. I'd wash my hands thoroughly before handling food or putting them anywhere near my face. If you're more comfortable spending a night or two away from home, go for it. It sounds like he's on the mend, whatever it is.
You have no idea what it's like living inside my head.
