Abstract

Carbapenem-resistant Acinetobacter baumannii is an opportunistic pathogen which has caused numerous health care-associated outbreaks particularly in intensive care and burn units. We describe an outbreak in a burn unit where 3 patients were identified as being colonized or infected with carbapenem-resistant Acinetobacter baumannii. A multifaceted approach and rapid implementation of infection prevention measures were effective in identification and removal of potential environmental reservoirs resulting in the prevention of further transmission.
