Holiday season overlaps with flu season, and no one wants to get sick on vacation. One doctor says the flu spreads during the winter primarily because we're more indoors.
So when you're on tight situations, like a plane, he says to make sure to keep your hands away from your face.
"When you're traveling, keep lots of hand wipes. I keep lots of wipes with me, and I'll wash down the arm rest of the airplane seat. I'll wash down the tray table," said Dr. Fred Pescatore.
