Re: Should we cancel our trip? Norovirus scare..
No, I don't think you should. It won't last that long on towels. Biggest risk is sometimes it lingers in the stools and 13 days is plenty. Go, see your parents, enjoy their company, have fun. Don't let this stupid phobia get in the way of your time together. They won't be around forever. Enjoy them while you can. Wash the dishes before eating off them if it concerns you and maybe bring along extra towels or purchase cheap ones so you don't have to use theirs. Buy a can lysol III once you arrive if it would make you more comfortable to disinfect a bit, like handles and such. Wash your hands frequently and keep them out of your mouth and you won't get sick.
