In July 2020, the Florida Department of Health was alerted to three Candida auris bloodstream infections and one urinary tract infection in four patients with coronavirus disease 2019 (COVID-19) who received care same dedicated COVID-19 unit an acute hospital (hospital A). C. is a multidrug-resistant yeast that can cause invasive infection. Its ability colonize asymptomatically persist on surfaces has contributed previous outbreaks health settings (1-7). Since first case identified 2017,...
Abstract Background Neonatal intensive care units (NICUs) provide life-sustaining to premature neonates and infants with complex medical needs. NICU patients are at high risk for healthcare-associated infections (HAIs) require nuanced infection prevention control (IPC) strategies due unique requirements equipment. Health departments key in providing IPC technical assistance NICUs outbreak response quality improvement initiatives; however, many health department personnel unfamiliar settings....
Abstract Background The US Centers for Disease Control and Prevention (CDC) provides technical assistance (consultations) to health departments responding single cases clusters of carbapenemase-producing organisms (CPOs). We aimed characterize consultations involving pediatric patients.Figure 1.Flow diagram screening CDC CPO requiring public responses or with suspected confirmed transmission.Abbreviations: AR, antimicrobial resistance; CPO, organism; HAI, healthcare-associated...
, a multidrug-resistant yeast, can spread rapidly in ventilator-capable skilled-nursing facilities (vSNFs) and long-term acute care hospitals (LTACHs). In 2018, laboratory serving LTACHs southern California began identifying species of
Abstract A nationwide tuberculosis outbreak linked to a viable bone allograft product contaminated with Mycobacterium was identified in June 2021. Our subsequent investigation 73 healthcare personnel new latent infection following exposure the product, recipients, surgical instruments, or medical waste.
In the United States, gold standard for malaria diagnosis is microscopic blood smear examination. Because not endemic in diagnostic capabilities may be limited, causing delays and increased morbidity mortality. A survey of practices U.S. laboratories was conducted from June to July 2017; members American Society Microbiology's listserv received a questionnaire inquiring about test availability, techniques, reporting. Results were assessed using Clinical Laboratory Standards Institute (CLSI)...
Background: Urinary tract infections (UTI) are the most common bacterial among infants and young children with fever without a source. Extended-spectrum β-lactamases (ESBLs) have emerged as emerging cause of UTI globally; however, data about risk factors clinical features ESBL-UTI been scarce. Objective: To describe predisposing factors, microbiologic associated pediatric UTIs caused by ESBL-producing bacteria (ESBL-PB). Methods: Our nested case-control study ran from January 1, 2012 to...
In 2015, an international outbreak of Mycobacterium chimaera infections among patients undergoing cardiothoracic surgeries was associated with exposure to contaminated LivaNova 3T heater-cooler devices (HCDs). From June 2017 October 2020, the Centers for Disease Control and Prevention notified 18 M. who had undergone at 2 hospitals in Kansas (14 patients) California (4 patients); 17 HCDs. Whole-genome sequencing clinical environmental isolates matched global strain identified...
During June 2017-November 2019, a total 36 patients with carbapenem-resistant Pseudomonas aeruginosa harboring Verona-integron-encoded metallo-β-lactamase were identified in city western Texas, USA. A faucet contaminated the organism, through environmental sampling, specialty care room was likely source for infection subset of patients.
Abstract Background Patients in long-term acute care hospitals (LTACHs) and skilled nursing facilities with ventilator units (VSNFs) are at high risk for Candida auris colonization; among patients colonized this emerging pathogen, 5%–10% develop invasive disease >45% mortality. In September 2018, a California LTACH-affiliated laboratory began enhanced C. surveillance by classifying species of isolated from routine urine specimens. February 2019, the first known Southern case was detected...
Outbreaks of emerging multidrug-resistant organisms (eMDROs), including carbapenem-resistant Enterobacterales, Acinetobacter baumannii, and Candida auris, have been reported among severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) patients. We describe eMDRO clusters in SARS-CoV-2 units associated infection control (IC) practices early the pandemic.
Abstract Background Prolonged hospitalization and unique physiology of neonates infants places them at risk for healthcare-associated infections (HAIs) in the neonatal intensive care unit (NICU). Development infection prevention (IP) bundles led to decreases HAIs NICUs. We interviewed key informants understand IP challenges opinions NICU clinicians inform needs Methods Participants were referred by Vermont Oxford Network (VON), an interdisciplinary quality improvement (QI) community. A...
Abstract Background The Centers for Disease Control and Prevention (CDC) tracks US outpatient antibiotic use in prescriptions per 1000 persons (Rx/1000), while the World Health Organization uses defined daily doses (DDD/1000), which are based on average adult dose, global surveillance. A third metric, days of therapy (DOT)/1,000 persons, has not been previously evaluated at national level. We aim to compare time trends oral as Rx/1000, DDD/1000, DOT/1,000 same data inform ongoing CDC...
In February 2020, during the early days of COVID-19 pandemic, 232 evacuees from Wuhan, China, were placed under federal 14-day quarantine upon arrival at a US military base in San Diego, California. We describe monitoring and responders for symptoms COVID-19, case contact investigations, infection control procedures, lessons learned to inform future protocols evacuated people hot spot resulting novel pathogen. Thirteen (5.6%) had COVID-19-compatible 2 (0.9%) laboratory-confirmed SARS-CoV-2....
