(NEW YORK) -- While the health hazards of increasingly competitive holiday shopping now include stampedes and pepper-spraying, bargain hunters can help assure that all they bring home from the mall are good deals, not other people's cold and flu viruses.
Shopping centers that teem with people also teem with their germs. But alcohol-based hand sanitizers and good old-fashioned hand-washing can defeat most common microbes.
Before hitting the mall, it pays to plan how you'll deal with germy hot spots:
Hand sanitizers and hand-washing cannot protect you from what's floating in the air, said Dr. William Schaffner, the chairman of preventive medicine at Vanderbilt University Medical Center in Nashville, Tenn. "The great hazard is being that close to so many people and being in everyone's breathing space," he said.
"We live in a world that's not sterile, but what we'd like to do is be hygienic, so let's try to avoid the obvious coughers and sneezers in the crowd. Go to another counter until they've passed," Schaffner advised. "If you are coughing and sneezing, put off your shopping a bit, which would be the kindest thing from a public health point of view."
Public restrooms can be a germ-laden nightmare, but they're also where you can wash away unwelcome microbes. Although soap dispensers and faucet handles "can be a little nasty," after being touched by people who have just done their business in the stalls, you can wash your hands thoroughly, then grab a paper towel and quickly turn off the faucet with the towel, Schaffner said.
Food Court Tables
Think about how many people have touched the tables, napkin dispensers and chair backs at a mall food court or restaurant, and you have another reason to wash your own hands or use a hand sanitizer. Just as kitchen sponges offer a warm, moist environment that lets food bacteria to multiply, the rags used to wipe down dirty tabletops are "a decent medium for bacteria to dwell in," said Dr. Jeffrey Boscamp, a pediatric infectious diseases specialist at Hackensack University Medical Center in New Jersey.
Most people grip the handrails when riding escalators inside malls and stores, leaving behind normal skin bacteria plus other germs picked up from rubbing their noses or mouths. Schaffner said he's not too worried about this particular hazard.
"If you use your hand sanitizer periodically during your afternoon safari at the mall, I think you'll be pretty well-protected," he said
All those sniffling tots inside toy stores, along with the healthy ones who just like to put everything in their mouths, can leave invisible coatings of germs behind -- not to mention what they spew into the air when they sneeze or cough.
"The number of hygienic children in the United States I can count on the fingers of my hands," Schaffner said. "I have to admit, children are the great disseminators of respiratory viruses. They do so because, first of all, when a virus infects a child, the child actually breathes out a lot of virus, more so than adults. They do so for a longer period of time."
The slick surfaces of smart phones and tablet computers can harbor a variety of germs, including staph, capable of living several hours. However, just because environmental hygienists can swab such surfaces and find a variety of bacteria doesn't mean they necessarily will make you sick, said Schaffner.
"Try out your candidate iPhone, look at it, play with it, and then do you hand sanitizer thing," he said.
Some Surfaces Not to Worry About
Although women frequently hear they should avoid shared testers at makeup counters, "infections associated with shared makeup are virtually nonexistent," Schaffner said. "They are not a recognized public health problem."
Worries about picking up germs from ATMs at the mall might be exaggerated, too, even if you've never see a bank employee wiping down ATM keys.
"If for some reason, you're a little queasy [about uncleaned keys], go the ATM, get your cash and use your hand sanitizer," Schaffner said.
