Just like to add my thanks to the OP. First post too so hello all. So much respect for everyone battling their emet demons, I'd like to think I'm not with an extreme case of emet but I reckon if I were to be viewed I'll be told otherwise. I've not had a virus for a few years and before that remember being ill once in my life. Touching all available wood.
I've visited friends who've recently had it over Christmas and my badminton doubles partner had it 2 days before a match I played in with him, I shook hands and everything!
So long as we keep our hand washing up, use common sense and stay healthy, it can't touch us. Thanks again to the OP. wish the media would give advice on how to prevent it rather than what to do if people have it. Prevention > cure!
