10 Ways You May Put Yourself at Risk for Flu (Without Realizing It!)
Hugging, kissing, and shaking hands
What's so dangerous about a simple handshake? Close contact with infected individuals is one of the easiest ways to pick up a virus. That doesn't mean you should be antisocial all flu season long, but you should be aware of possible transmission opportunities. If you are in a situation where physical hellos or good-byes are necessary, try not to touch your mouth or eyes afterward until you can wash your hands.
The Centers for Disease Control and Prevention (CDC) recommends maintaining a 6-foot buffer from sick people to cut down on the virus's ability to spread. So, as a precautionary measure, all sorts of cultural greetingsfrom shaking hands to hugging to kissing on the cheekare getting the ax.
