Anyone entering or leaving should really go through a decontamination procedure. The facilities improvements and employee training costs a lot of money. If it were up to me, I would virtually end public access to certain hospital areas. It is not a pretty picture, but what you cannot see will kill you.
It is bad enough so many people were too lazy or too stupid to finish their antibiotic prescriptions which lead to a lot of the multidrug-resistent organisms, now many will be too lazy or too cheap to assist in the effort to contain them.
containment is not possible. We see nearly as many MRSA infections acquired in the community as in the hospital. The bug has been around for years. It is not one of the things that keeps me awake at night as a hospital worker. I suspect I have been colonized for years, and probably the rest of my immediate family as well
This is not a bug that causes a lot of problems for people with normal immune systems. Now talk about pseudomonas, VRE, or acinetobacter and I might agree with you. THese are much rarer, more virulent, and MAY have some utility in trying to contain.
