Healthcare Quality and Worker Safety Information

Publications Morbidity and Mortality Weekly Report (MMWR): Klebsiella pneumoniae Carbapenemase–Producing Enterobacterales Infection and Colonization in a Long-Term Care Facility — Ontario, Canada, May 2024–January 2025 – This report highlights findings from an 8-month outbreak of carbapenemase-producing Enterobacterales (CPE) in a long-term care facility (LTCF) in Ontario, Canada, involving five residents. All five affected residents were older adults with multiple comorbidities (including patients with frequent antibiotic use or an indwelling device such as a urinary catheter) who lived in the same unit and shared multiple potential exposure sources that likely contributed to the spread. Investigators identified spread of a resistant strain of Escherichia coli and transmission of a resistance-related plasmid between bacterial species, indicating dual organism- and plasmid-mediated transmission. Adoption of LTCF risk-based admission screening, clear interfacility transfer communication, prompt implementation of contact precautions for asymptomatic carriers, routine hand hygiene, compliance with infection prevention and control practices, and focused environmental controls coupled with antimicrobial stewardship could help prevent future outbreaks.

The overall risk to the American public and travelers remains low, but as with other high-consequence infectious diseases, clinicians are often the first to diagnose an outbreak. During this COCA Call on Thursday, May 28, 2026, from 2:00 PM – 3:00 PM EDT, learn more about this outbreak, the history and ecology of Bundibugyo virus, what U.S. clinicians should know about preparing for, diagnosing, and managing patients with suspect or confirmed Ebola disease, and how to prevent Ebola viruses from spreading.
