An Observational Study to Determine the Prevalence of COVID-19 Among Hospitalized Patients With Multidrug-Resistant Enterobacterales Infections and Clinical Outcomes, 10 US Sites, 2020--2022.

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.

Carbapenem-Resistant and Extended-Spectrum β-Lactamase-Producing Enterobacterales in Children, United States, 2016-2020.

2019–2020 at 6 US sites. Among 159 CRE cases in children (median age 5 years), CRE was isolated from urine for 131 (82.4%) and blood from 20 (12.

Carbapenem-resistant Acinetobacter baumannii complex in the United States-An epidemiological and molecular description of isolates collected through the Emerging Infections Program, 2019.

Background: Understanding the epidemiology of carbapenem-resistant A. baumannii complex (CRAB) and the patients impacted is an important step toward informing better infection prevention and control practices and improving public health response.

Methods: Active, population-based surveillance was conducted for CRAB in 9 U.

Trends in Incidence of Carbapenem-Resistant Enterobacterales in 7 US Sites, 2016─2020.

Background: We described changes in 2016─2020 carbapenem-resistant Enterobacterales (CRE) incidence rates in 7 US sites that conduct population-based CRE surveillance.

Methods: An incident CRE case was defined as the first isolation of , spp., or spp.

Distinct Origins and Transmission Pathways of across Three U.S. States.

Carbapenem-resistant (CRE) are among the most concerning antibiotic resistance threats due to high rates of multidrug resistance, transmissibility in health care settings, and high mortality rates. We evaluated the potential for regional genomic surveillance to track the spread of -carrying CRE (KPC-CRE) by using isolate collections from health care facilities in three U.S.
