Tracing local and regional clusters of carbapenemase-producing ST512 with whole genome sequencing, Finland, 2013 to 2018.

BackgroundTwo epidemiologically-unrelated clusters of carbapenemase (KPC)-producing were detected among several healthcare facilities (HCF) in Finland by routine surveillance using whole genome sequencing (WGS).AimThe objective was to investigate transmission chains to stop further spread of the responsible strain.MethodsIn this observational retrospective study, cases were defined as patients with KPC-3 sequence type (ST)512 strain detected in Finland from August 2013 to May 2018.
