Should we sterilize footwear in hospitals?

Sani - When you look at the issue of contamination in hospitals and transferral of organism particularly in relation to C. difficile we know that most of the contamination comes from patients that are already infected with the infection, with the disease, with the organism. The crucial thing really is to make sure that you clean the surfaces. You clean the sites where you touch quite frequently by healthcare workers. You also isolate the patient who's symptomatic. It's less of an issue in terms of people bringing it in. You're not going to bring it in from the community on your footwear, for instance.
