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.
There are likely many more sources than we have suspected and not all of them naturally occurring either as there is some justifiable speculation about weaponizations. The CDC is really looking at this and there is also a special division within the USDA working to detect other sources.
