Many Americans will soon be hitting the airports to embark on their holiday travel. And that means, so will all their germs. Here are some tips for not getting sick while traveling. You're more at risk for illness if you sit next to or in front of a passenger who is sick. Be sure to turn on the overheard fan to keep the air circulating around you.
