'Nightmare' Superbug May Have Spread Outside Hospitals

Six people in Colorado recently became infected with a "nightmare" superbug that until now, has mostly been limited to people in hospitals, according to a new report. The new cases suggest the superbug may have spread outside of health care facilities. The superbug is known as carbapenem-resistant Enterobacteriaceae, or CRE, a family of bacteria that are difficult to treat because they are resistant to powerful antibiotics.
