Title: First report of nosocomial outbreak of vancomycin-resistant Enterococcus faecium infection among COVID-19 patients hospitalized in a non-intensive care unit ward in Slovakia

Abstract: BACKGROUND: Enterococcus species account for most of the human enterococcal HAI and multidrug-resistant infections and have become a major threat to modern public health. We examine the rise in the number of vancomycin resistant E. faecium blood stream and urinary tract infections in a COVID-19 department during an epidemiologic outbreak investigation to detect and eliminate nosocomial clusters of the bacteria.
METHODS: Strain identification was performed by classical isolation and biochemical and cultivation methods. Antibiotic testing results were interpreted according to European committee on antimicrobial susceptibility testing (EUCAST) guidelines. Six isolated samples underwent the whole genome sequencing (WGS) during the outbreak investigation. Isolate relatedness was determined using the core genome multi-locus sequence typing.
RESULTS: WGS revealed two genotypically distinct VRE clusters, one of which had genetically closely related patients and environmental isolates. The cluster was terminated by enhanced infection control strategies.
CONCLUSIONS: This study provides the first description of an outbreak caused by vanB-ST117 and vanA-ST17 E. faecium strains among COVID-19 patients in Slovakia. This study can help to raise the awareness about the need for strict adherence to infection control measures and the implementation of rational antimicrobial stewardship as a routine part of COVID-19 management (Tab. 3, Fig. 3, Ref. 27).
