With quite a bit of travel I've learned to keep the antibacterial handy-wipes around. If you spend a lot of time in hotel rooms, take a wipe or two and hit the stuff that has likely been handled a lot: TV remote control, phone, door handles, light switches, sink handles, toilet handles, etc. (Of course, be sure to hit the toilet handle LAST not first!) <img src="/images/graemlins/grin.gif" alt="" />

Ditto on the frequent hand-washing. Also keep a bottle of Purell hand sanitizer around for when you're not close to a sink.

I can honestly say (knock on wood) that all of these steps work.
