The spread of "superbugs"

It's as if the Economist knew that SHEA was in session. They just published a briefing on the many reasons behind the spread of resistant bacteria. My favorite quote from the article is that "much of modern surgery relies on the risk of infection remaining low. At the moment, it is close to zero. If resistant strains raise it to even 5%, let alone 10%, a lot of orthopaedic surgery, cataract replacements and other discretionary but life-enhancing procedures would simply stop. That would not be the end of the world, but it would be a step backwards."
