Researching whether fist-bumps indeed would transmit less bacteria than a handshake, I found that, apparently, shaking hands with your doctor is a thing in the US, and, apparently, is expected by both the doctors and the patients; as well as shaking hands in general between the staff at the hospitals.

Ignoring what you'd think is an instance of an obvious ignorance of the germ theory of disease, is this at all expected within the health facilities of universal healthcare countries, too, or is this practice rather limited outside of the US?
