Mxw08,
I am so sorry; this is such a horrible thing to have to face. The truth about Norovirus is that you cannot catch it from people breathing on you, but can catch it if someone v*s or defecates and then does not wash his or her hands, and touches a surface, and then YOU touch it; or, of course, if you ingest the particles from the v* or feces.
I also feel insanely jealous of such people. At least I know I'm not alone, and that helps more than I can say.
Please do let us know how things are going.
