mango - the whole Norovirus thing has gotten blown way out of proportion. The virus is nothing more than what we have always known as the common 24hr stomach bug. Your son has a better chance of catching this bug if he went to daycare than if you take him on a cruise. Actually it would be good for his immune system if he did come down with this bug, it won't make for a fun couple of days though. Use common sense, preventative hand washing, Purell hand sanitizer. this virus is found everywhere people gather in confined spaces for a long period of time- airplanes, hospitals, nursing homes, cruise ships are low on the list.
