Researchers: Fist bumps transmit far fewer germs than a handshake

NEW YORK (WABC) -- Fist bumping - it's the move that is making a comeback, thanks to our Commander in Chief.

Now, a new study in the Journal of Infection Control says the fist bump may help stop the spread of germs, calling it a "more hygienic alternative to the handshake".

Researchers in Wales dipped gloves in E Coli bacteria, and tested 3 popular greetings. The handshake transfers 10 times more bacteria than a fist bump, and twice as much bacteria as a high five.

"What they found is the amount of surface area with a fist bump is so much less than with the other methods," says Dr. Bruce Hirsch of North Shore LIJ Hospital.

Dr. Bruce Hirsch is an infectious disease specialist, and says that they are seeing a lot of scary infections right now.

"We can take simple precautions and stay healthy," Dr. Hirsch adds.

They also found that duration and grip matter - the longer the handshake and the stronger the grip, the more bacteria you transfer. However, a firm handshake is more than just a shake - it conveys confidence, goodwill and respect.

Many people Eyewitness News talked to say they think the fist bump is more for causal friends.

"If you go to shake somebody's hand, and they put out their fist or elbow, I think they are going to feel insulted in some way," says bus driver Herbie Walters.

Walters believes a good, firm handshake is still the way to go, and hopefully the other person washed their hands.

"You got to do what you can do - hope for the best!" Walters says.
