I've noticed that toilets in hospitals *always* have paper towels and
pedal-operated bins. (Occasionally they have dryers in addition, but
they always provide paper towels.) I think that's strong evidence
that medical people consider paper towels to be the most hygienic
option.

Round here, they also have hygenic "dry" hand wash that doesn't require
towelling off. It is compulsory to wash your hands with it every time you
enter or leave a ward.
