My husband threw up 6 times in one night no diarrhoea no fever no medication no alcohol. would this be food poisoning or stomach flu? he was fine the next day. its been three days can he mix with the rest of the house now? ive had him in isolation?

It could have been either food poisoning or a viral infection but after 3 days of feeling well, it is likely ok to stop isolation. If no one else got sick yet, you probably won’t get sick. Practice good hand hygiene and you should be all set. Glad he’s feeling better!

Norwalk agent has the virus that causes these type symptoms. Symptoms like this that resolve in 24 hours are not a concern, except good hygiene to avoid spreading it to other close contacts
