From everything I've read the MAXIMUM amount of time the virus can live is 2 weeks (on surfaces, shedding in stool, etc.). So I'd say that it is now enough time.

How was it? My husband had norovirus last Monday (about exactly one week ago around this time), and I still haven't touched/kissed him and have been extra careful about cleaning my hands and bathroom and such. I sure hope I can kiss him and touch him again in a week!
