Nationwide, population-based observational study of the molecular epidemiology and temporal trend of carbapenemase-producing Enterobacterales in Norway, 2015 to 2021

directly related to import points towards potentially unidentified transmission routes. A decline in travel associated cases was observed during the COVID-19 pandemic. Conclusions: The close-to-doubling of CPE case incidence between 2015 and 2021 was associated with foreign travel and genomic diversity. To limit further transmission and outbreaks, continued screening and monitoring is essential.

Automated summary

The incidence of Carbapenemase-producing Enterobacterales (CPE) infection almost doubled between 2015 and 2021, and it was associated with foreign travel and genomic diversity. Continued screening and monitoring are essential to limit further transmission and outbreaks.
