STAUNTON, Va. (WHSV) -- The president does it, and so do celebrities.
Now the growing popularity of the fist bump and greater awareness about spreading germs could make the hand shake a thing of the past.
Coughing, sneezing and then shaking hands.
Entire websites are dedicated to stop handshaking, for that reason.
You can even buy a lapel pin to help you politely decline one.
The CDC estimates up to 80 percent of infections are spread by hands.
"I think the general concern is contact with the underside of the hand, which is what you use to engage, possibly touching your face, or in the health care setting, used to take care of patients. I think minimizing the contact that occurs there is probably what people are targeting," said Jonathan Falk, the district epidemiologist for the Central Shenandoah health district.
Falk said the key, whether you are a hand-shaker or a fist-bumper, is to wash your hands.
