Quarterly Carbapenemase Producing Enterobacteriaceae (CPE) Surveillance Reports


  • Since 2008, there have been documented reports of CPE in Ontario hospitals, however, little is currently known about the extent of occurrence in the province. In December 2011, Public Health Ontario (PHO) in collaboration with the Ministry of Health and Long‐Term Care initiated a voluntary surveillance program to assess the epidemiology of CPE in Ontario. Epidemiological data is critical for informing infection prevention and control policies and procedures that will help prevent the likelihood of CPE becoming endemic in Ontario.
