DH vomiting - should he stay away?

[Garageinconstantuse]

DH has just returned from a European country this afternoon. Complained of headache, chills and feeling sick and went to lie down, and then was v sick (which basically never happens to him). I think there's a high chance he's picked up norovirus/similar on his trip. We have a spare room and bathroom he can use. It's reasonable for him to keep a bit of distance until he starts to feel better, right? Or am I being over-cautious post-covid? Is there any way to differentiate food poisoning (which presumably would not be catchy)?

No I would definitely isolate him if there is a place to do it.

If you have a spare room and bathroom I can’t see any reason why you’d share even if it was good poisoning, why would you want to share a bed or bathroom with someone throwing up if you don’t have to? Not over cautious at all OP

Some forms of food poisoning are contagious.

If you have a spare room and bathroom for him to use, it’s fair enough to ask him to stay in there until he’s stopped vomiting, but I would be checking on him regularly and probably bringing him water and bland snacks if he’s as unwell as he sounds!

Thanks all! I thought this was sensible but then suddenly had a moment of self-doubt. It doesn't help that he's been away for a week so it feels particularly unfair. But he's ok with it. I will definitely be checking all is ok and providing supplies of whatever is needed.

Definitely isolate him!

TBH I started with something like this Christmas night. I never vomit either, I scared myself. It mutated into sinusitis, I started antibiotics for it a couple of days ago.
