This is called CA-MRSA...that is, Community Acquired Methicillin Resistant Staphylococcus Aureus...as compared to HA-MRSA...that is, Hospital Acquired MRSA which has been around for a while. As a retired nurse, I am not finding it difficult to see how HA became the 'mysterious'CA. I see nurses and other hospital personnel in the community in their 'scrub' uniforms. They go everywhere in these supposed 'uniforms.' I see them in restaurants, grocery stores, bookstores, office supply stores...everywhere. Everything they touch has the potential to carry unknown amounts of hospital-grade bacteria (the worst!)that can be picked up by anyone. I wish somebody in a position of authority could put this obvious 'two and two' together and insist that healthcare personnel not wear the same clothing in and out of the hospital. Call me old-fashioned.
You are absolutely right. I see people in scrubs all over the place from the supermarket to restaurants.
