Travel Bug

Forget stale air and reusable blankets: It's the person in 27B you should be worried about. While filtration systems on airplanes are supposed to prevent a cold or flu virus from circulating in the air, there's nothing to stop it from passenger-hopping. And with travelers topping more than 4.6 million during last year's holiday season, that's a lot of to-and-fro for the flu. "If someone is sick on a plane, the people sitting next to him, behind him, and in front of him are at risk for getting sick," says Zachary Rubin, MD, an assistant professor of epidemiology at Santa Monica-UCLA Medical Center. "The rule of thumb is everyone within three feet is at risk."

Nasty Neckties

An ugly tie just took on a whole new meaning. Researchers at the New York Hospital Medical Center of Queens found that almost half of the neckties worn by doctors were swarming with disease-causing germs. In fact, doctors' ties were found to be eight times as likely to harbor germs as those of security personnel, who apparently have an undeserved reputation for being slovenly. Why the germ factory on neckties? It probably stems from the inordinate amount of sneezing a doctor's professional attire must face on a daily basis. And since we know that sneezes are laden with flu and cold viruses, maybe we're all better off seeing doctors who adhere to "casual Fridays."

Close Encounters

Almost 2 billion people ride New York City's 4,000 subway cars every year. So, short of buying a hermetically sealed hazmat suit, fuggedaboudit: If you're a straphanger, you're on track for a close encounter with germs that cause cold and flu. And that risk goes beyond the Big Apple: Whether it's a trolley in San Francisco or a steamboat on the Mississippi, flu and cold viruses find a way to stow away -- no matter where the road trip.

Touch & Go

Germs can live on surfaces like doorknobs for more than two hours. And with working adults touching as many as 30 objects an hour, that means washing your hands frequently -- after using the bathroom, eating, working or playing outdoors, playing with pets, or coughing, sneezing, or blowing your nose -- to keep them clean. It takes warm water, soap, and 15 to 20 seconds of scrubbing to rid them of cold and flu germs. P.S.: While 95% of people say they wash their hands after using a public restroom, only 67% actually do -- yikes! Of that group, just 33% use soap, and only 16% wash their hands long enough to make it count.
