Study Says Fist Bumps Spread Fewer Bacteria Than Handshakes Or High-Fives

By  | 

Fist bumps spread fewer germs than handshakes and even high-fives.

That's what researchers in Wales say.

Researcher David Whitworth says fist bumps spread only one-twentieth the amount of bacteria that handshakes do.

And, he says high-fives pass along about half the germs handshakes do.

The results of his study are online in Monday's American Journal of Infection Control.
