Back in August 2009 I had not been near a hospital in about a decade. I caught a case of MRSA in my armpit and ended up at Dewitt Army Hospital in serious condition for four days.
The doctors told me MRSA is now everywhere and they think close to 50% of the population have it on their bodies. It just takes the right conditions, including the host being ill and their defenses being down for the infection to attack.
A relative of mine was on a hike ...slipped on some rocks and scraped his shin up pretty good. He almost lost that leg to MRSA ... they cleaned it out to the bone ... if it had been in the bone, bye-bye leg. It took months to heal and required a wound specialist’s care.
