Hospitals in the Carolinas are dealing with a growing threat from a type of superbug. It's only infected a small percentage of patients. But that percentage is on the rise, and the infections can be deadly.
The superbug is called CRE, and a recent report from the Centers for Disease Control describes it as "nightmare bacteria."
Dr. Katie Passaretti of Carolinas HealthCare System said it's evolved into something extremely difficult to treat.
