When I see random people dying of bacterial infections in this day and age I can't help but feel like the misuse/overuse of antibiotics has us sliding backwards in medical progress and we will continue to lose great minds to this irresponsibility.
Also, Bactria exchange genetic material on a regular basis so things often concentrate in hospitals even if the source of the mutation is on a farm somewhere. The good news is that super bugs often provoke a strong response from the healthcare community which can quarantine the people / area and generally stop the spread of specific agents.
PS: What makes this even more frightening is you can't safely do operations without antibiotics as they basically guarantee infection.
