when my father contracted MRSA in 1997, he was placed in isolation (to protect him) and treated with steroids and vancomycin. vanco (a super-powerful antibiotic) was the only drug effective at treating MRSA at the time. his immune system was already compromised because of the drugs he took for RA and he died about 6 months after contracting MRSA.
two years later my mother had nasal surgery and the docs confirmed that she had colonized MRSA (ie was carrying it all this time). she was placed in isolation and treated with vanco. she didn't die.
in 2005, I suffered a post-surgical infection in one of my salivary glands. my doc confirmed it was also MRSA (apparently I had colonized it 8 years prior). I was not hospitalized (this surprised me) but was treated with vanco. I didn't die either.
I remember a statistic from 1997 when my father contracted MRSA that approximately 80% of all hospital personnel were colonized with MRSA. my father contracted MRSA during surgery (spinal fusion). if my mother and I really weren't colonized in 1997 (as assumed by our docs), one could then assume that we also contracted MRSA during surgery.
hospitals can be scary places. I truly believe you shouldn't stay there any longer than necessary -- it's just too dangerous with lots of germies (like MRSA) just waiting to get you!
