A recently published study says replacing handshakes with fist-bumps could reduce the spread of infection in hospitals.
Published in the Journal of Hospital Infection, a group of doctors and researchers from West Virginia University compared bacteria spread between open hand-shakes and fist bumps.
They found exposure of handshakes lasted almost three times as long and, on testing, revealed much larger levels of bacteria.
The unusual study is being considered seriously by some, with growing concern about the spread of anti-biotic resistant bacteria in hospitals.
Many hospitals have already removed door handles because they contained five-times the amount of bacteria than push-doors.
