Another superbug. MRSA started out only in health care settings also. Then it spread to hospitals and then to the community.

Carbapenem-Resistant Klebsiella Pneumonia (CRKP)

Drug-resistant 'superbug' mostly limited to Southern California nursing homes, health officials say

A drug-resistant bacterium that has surfaced in Southern California has mostly spread in nursing homes, not hospitals, but more needs to be done to track it, health officials said Thursday.
More than 350 cases of Carbapenem-Resistant Klebsiella pneumoniae, or CRKP, have been reported at healthcare facilities in Los Angeles County, mostly among elderly patients at skilled-nursing and long-term care facilities, according to a study by Dr. Dawn Terashita, an epidemiologist with the Los Angeles County Department of Public Health.
