Abstract

We describe an outbreak of carbapenem-resistant Acinetobacter baumannii (CRAB) in a COVID-19 dedicated hospital. The suspected mechanism of transfer was an environmental source that persisted despite evacuation and terminal cleaning of the entire hospital, and transmitted through healthcare workers' hands or equipment. This outbreak demonstrates that practices to prevent the spread of multidrug-resistant organisms must not be neglected during the COVID-19 pandemic.

Keywords: COVID-19 pandemic; Carbapenem-resistant Acinetobacter baumannii (CRAB); Environmental sampling; Infection control; Outbreak investigation; Screening.

Fourier-transform infrared spectroscopy (FT-IR) bio-typing analysis of carbapenem-resistant Acinetobacter baumannii (CRAB) clinical and environmental specimens (n=24) from the Hasharon outbreak. The blue line represents the automatic cut-off value (0.042) generated by the manufacturer's software. A. baumannii ATCC 19606 and a CRAB isolate belonging to international clonal lineage 3 (IC3) and harboring blaOXA-23 and blaOXA-24 genes were added as control strains to increase discriminatory power. Clusters composed of two or more isolates are shown in orange and singletons in green.
