Newest firstBackgroundHealthcare-associated infections pose a major burden to neonatal health worldwide and remain difficult to track in low-resource hospitals because patient movement data and pathogen genomic data are rarely integrated into actionable transmission models. Existing approaches are often restricted to specific settings, highly structured electronic health records (EHRs), or analyses focused on either patient m…
Open article record in new tab ↗Candida auris emerged in Chicago, IL, USA in 2016 and has since become endemic. We used whole genome sequencing (WGS) of 494 isolates, epidemiologic metadata, and patient transfer data to describe the transmission of C. auris among Chicago healthcare facilities between 2016 - 2021. 99% of isolates formed a single clade IV phylogenetic lineage, suggesting a single introduction. Isolates were grouped into genomic cl…
2.Healthcare-associated wastewater reservoirs and asymptomatic gastrointestinal patient colonisation by carbapenemase-producing Enterobacterales (CPE) contribute to nosocomial CPE dissemination. We systematically sampled wastewater sites (n=4488 sampling events; 349 sites) and patients (n=1247) across six wards over 6-12 months in 2016 to better understand blaKPC-associated CPE (KPC-E) diversity within these niche…
Open article record in new tab ↗Estimating key aspects of transmission is crucial in infectious disease control. Serial intervals - the time between symptom onset in an infector and infectee - are fundamental, and help to define rates of transmission, estimates of reproductive numbers, and vaccination levels needed to prevent transmission. However, estimating the serial interval requires knowledge of individuals contacts and exposures (who infec…
BackgroundCarbapenem-resistant Enterobacterales (CRE) harboring blaKPC have been endemic in Chicago-area healthcare networks for more than a decade. During 2016-2019, a series of regional point prevalence surveys identified increasing prevalence of blaNDM-containing CRE in multiple long-term acute care hospitals (LTACHs) and ventilator-capable skilled nursing facilities (vSNFs). We performed a genomic epidemiology…
Open article record in new tab ↗Clostridioides difficile is the leading cause of healthcare-associated infectious diarrhea. However, it is increasingly appreciated that healthcare-associated infections derive from both community and healthcare transmission, and that the primary sites of C. difficile transmission may be strain dependent. We conducted a multisite genomic epidemiology study to assess differential genomic evidence of healthcare vs.…
BackgroundKlebsiella pneumoniae and close relatives are a growing cause of healthcare-associated infections for which increasing rates of multi-drug resistance are a major concern. The Klebsiella polysaccharide capsule is a major virulence determinant and epidemiological marker. However, little is known about capsule epidemiology since serological typing is not widely accessible, and many isolates are serologicall…
