Background: The COVID-19 pandemic in 2020 exerted immense pressure on health care systems worldwide, causing substantial resources to be diverted to respond to the pandemic. These changes raise the concern about the potential for reduction in adherence to long-established measures in the prevention of healthcare-associated infections (HAI). Enterococcus species account for most of 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 whole genome sequencing (WGS) during the outbreak investigation. Isolate relatedness was determined using core genome multilocus sequence typing.
Results: WGS revealed two genotypically distinct VRE clusters, one of which had genetically closely related patient and environmental isolates. The cluster was terminated by enhanced infection control strategies.
Conclusions: This study provides the first description of an outbreak caused by vanA-ST17 E. faecium strains among COVID-19 patients in central Europe, and the first description of an outbreak caused by vanB-ST117 and vanA-ST17 E. faecium strains in Slovakia. This study can help raise 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.
