For how long is norovirus infectious in a house?

Infection-control nurse Rachel Thaxter answered this question...

Rachel - Well, at least for 48 hours.

Chris - I don't think he's implying he's going to cook dinner while he's having vomiting.

Rachel - Obviously not.

Chris - How long should people not come around your house for?

Rachel - If you're really good at cleaning, perhaps a week, clean your house a couple of times, your bathroom is the key area, the kitchen, a week.

Chris - So, defer that dinner party for a week Mark and you'll probably be alright!
