LH, hospitals are great places to catch stuff. I worked in them for about 18 years. I'd move, have colds off and on for about six months then went to 3 or 4 times a year until I went somewhere else, then it would all happen again. I've been taking echinacia (off and on) since last Nov, and the last cold I had was in Oct. (First winter I can remember in my life with no cold.) I don't know if it's the echinacia or I've been lucky, but it sure isn't hurting anything!

By the way, I hope I'm wrong about the 'tip of the iceberg' thing. It's mainly my cynicism about human nature that makes me believe attempts at quarantine aren't going to be as effective as they should be.
