I read a report about mrsa once that also talked about cleaning procedures. Hospitals get overloaded with staph naturally, and hard as they tried you can't get all the bugs. Those that survive mutate and become stronger. Were it antibiotic overuse alone it would be rampant but certain hospitals are known carriers. Surgery, open skin.... viola, instant blood born exposure with no chance to fight it with your immune system. A friend got it the same way and is also still healing from thst surgery from over a year ago. Skin won't seal.
