Make a hand-held air sanitizer. Moisten a washcloth with 80-20 water/chlorine mix. Keep it in a ziploc bag and in your purse/pocket when you travel. If you get stuck in an elevator or other confined space with someone coughing cover your mouth with it and breath through it.

Clorox is making an antimicrobial household spray and they might have a pocket size.
