I am not a medical or health professional - hence the possible
ignorance of my question.  I hope the group will indulge my curiosity.

In an age when there are antibacterial/antiviral hand liquids which
can kill any known micro-organism, and when surgeons are gowned and
gloved with sterile products, is the surgeons' scrubbing-up process
still really necessary?  It seems somewhat belts-and-braces but that's
from a layman.
