I have wondered about this myself. Luckily, I live in an area where people don't travel a whole lot. I really don't know, but thanks for posting this. I would be very interested in any insight myself. A few weeks ago, when I was in the lab getting bloodwork done, this little kid sat right next to me with the nastiest wheeze and hack you'd ever heard in your life. All I could think about was SARS and my baby. I found out though, the kid was from a town in the sticks that nobody ever comes into or out of, so the chances seemed remote. I caught a cold the very next day and was worried. I never got that sick, though, and I'm fine now. But I think this SARS thing does have alot of us on edge!
