Background: We investigated hospitalized carbapenem-resistant Enterobacterales (CRE) and extended-spectrum β-lactamase-producing Enterobacterales (ESBL-E) cases with and without COVID-19, as identified through Emerging Infections Program surveillance in 10 sites from 2020 to 2022.

Methods: We defined a CRE case as the first isolation of , complex, , , , or resistant to any carbapenem. We defined an ESBL-E case as the first isolation of , , or resistant to any third-generation cephalosporin and nonresistant to all carbapenems tested.

Article Synopsis
  • Carbapenem-resistant Enterobacterales (CRE) are mostly linked to healthcare settings but are increasingly being found in the community.* -
  • A study from January 2012 to December 2015 identified 1499 cases of CRE, with 10% classified as community-associated, primarily affecting White females and detected mostly in urine samples.* -
  • Some community-associated isolates contained carbapenemase genes, highlighting the need for ongoing surveillance of CRE outside healthcare environments to track their emergence.*

Background: Carbapenem-resistant Enterobacterales (CRE) are highly antibiotic-resistant bacteria. Whether CRE resistant only to ertapenem among carbapenems (ertapenem "mono-resistant") represent a unique CRE subset with regards to risk factors, carbapenemase genes, and outcomes is unknown.

Methods: We analyzed surveillance data from 9 CDC Emerging Infections Program (EIP) sites.
