Carbapenem-Resistant Enterobacteriaceae Outbreak in a Medical Ward in Spain: Epidemiology, Control Strategy, and Importance of Environmental Disinfection.

Carbapenem-resistant Enterobacteriaceae (CRE) are a growing public health problem. We describe an outbreak by CRE and the measures to control it in a hospitalization unit in Spain. In June 2015, the system of prevention and control of CRE implemented in the hospital detected an increase in the incidence of patients with CRE in a mixed hospitalization facility (geriatrics, internal medicine, and pneumology), with the appearance of four related patients in 2 weeks, three of them being nosocomial cases.
