Bumping Fists to Stop the Spread of Germs?

the MPR take:

Could fist-bumping become a new means of infectious disease prevention? Although shaking hands is a commonly accepted greeting, bumping fists could be a more hygienic way to say hello. A new study in the American Journal of Infection Control coated rubber gloves with E. coli to evaluate bacterial transmission via handshakes, high-fives, and fist-bumps. The handshake transferred the greatest number of E. coli, with an increase seen with stronger grip strengths. While the number of transferred bacteria was reduced by over 50% with a high-five, bumping fists had a 90% lower transmission rate compared to the handshake. The researchers hypothesize that the fist-bump transfers fewer germs due to the quickness of the action and the smaller surface area, when compared to a handshake or a high-five.

President Barack Obama's famous fist bumps may have health benefits as well as a cool factor, because a new study shows that greeting someone with your knuckles is much more hygienic than shaking their hand. Dave Whitworth, of Aberystwyth University in Wales, tested the germ-carrying potential of various greetings by high-fiving, fist-bumping, and shaking hands with with a PhD student.
