IJID Reg 2024 11 100361 OBJECTIVES: The spread of extended-spectrum cephalosporin-resistant Enterobacterales (ESCrE) and carbapenem-resistant Enterobacterales (CRE) has resulted in increased morbidity, mortality, and health care costs worldwide. To identify the factors associated with ESCrE and CRE colonization within hospitals, we enrolled hospitalized patients at a regional hospital located in Guatemala. METHODS: Stool samples were collected from randomly selected patients using a cross-sectional study design (March-September, 2021), and samples were tested for the presence of ESCrE and CRE. Hospital-based and household variables were examined for associations with ESCrE and CRE colonization using lasso regression models, clustered by ward (n = 21). RESULTS: A total of 641 patients were enrolled, of whom complete data sets were available for 593. Colonization with ESCrE (72.3%, n = 429/593) was negatively associated with carbapenem administration (odds ratio [OR] 0.21, 95% confidence interval [CI] 0.11-0.42) and positively associated with ceftriaxone administration (OR 1.61, 95% CI 1.02-2.53), as was reported hospital admission within 30 days of the current hospitalization (OR 2.84, 95% CI 1.19-6.80). Colonization with CRE (34.6%, n = 205 of 593) was associated with carbapenem administration (OR 2.62, 95% CI 1.39-4.97), reported previous hospital admission within 30 days of current hospitalization (OR 2.58, 95% CI 1.17-5.72), hospitalization in wards with more patients (OR 1.05, 95% CI 1.02-1.08), hospitalization for ≥4 days (OR 3.07, 95% CI 1.72-5.46), and intubation (OR 2.51, 95% CI 1.13-5.59). No household-based variables were associated with ESCrE or CRE colonization in hospitalized patients. CONCLUSION: The hospital-based risk factors identified in this study are similar to what has been reported for risk of health care-associated infections, consistent with colonization being driven by hospital settings rather than community factors. This also suggests that colonization with ESCrE and CRE could be a useful metric to evaluate the efficacy of infection and prevention control programs in clinics and hospitals. |
Legionnaires' disease in transportation, construction and other occupations in 39 US jurisdictions, 2014-2016
Harduar Morano L , Morawski BM , Herzig CTA , Edens C , Barskey AE , Luckhaupt SE . Occup Environ Med 2024 BACKGROUND: Certain workers are at increased risk for acquiring Legionnaires' disease compared with other workers. This study aims to identify occupations at increased risk for acquiring Legionnaires' disease. METHODS: Using data from the US Centers for Disease Control and Prevention's Supplemental Legionnaires' Disease Surveillance System, this study identified Legionnaires' disease confirmed patients ≥16 years of age in 39 states with reported symptom onset during 2014-2016. Age-adjusted and sex-adjusted incidence rate ratios (IRR) stratified by occupation group were calculated by comparing Legionnaires' disease patients in an occupation group (eg, transportation) to those in all other occupation groups (eg, non-transportation). RESULTS: A total of 2553 patients had a known occupation group. The two occupations with the highest burden were transportation (N=287; IRR=2.11) and construction (N=269; IRR=1.82). Truck drivers comprised the majority (69.7%) of the transportation occupation group and construction labourers comprised almost half (49%) of the construction occupation group. The healthcare support occupation had the highest IRR (N=75; IRR=2.16). CONCLUSION: Transportation and construction workers, who are generally not covered by guidance related to building water systems, have increased risk of Legionnaires' disease compared with other workers. One hypothesised risk factor for truck drivers is the use of non-genuine windshield cleaner in their vehicles. A simple intervention is to use genuine windshield cleaner with bactericidal properties (ie, includes isopropanol/methanol) which can reduce the risk of Legionella growth and transmission. To improve surveillance of Legionnaires' disease and identification of similar exposures, the authors encourage the collection of occupation and industry information for all patients with Legionnaires' disease. |
Assessment of school staff knowledge and perceptions of student e-cigarette use and resource needs, and e-cigarettes confiscated at 12 North Carolina high schools-2019
Tanz LJ , Heck C , Herzig CTA , Ranney LM , Herndon S , Martin J , Hast M , McGowan E , Baler G , Shamout M , King BA , Tynan MA , Kansagra SM . NC Med J 2023 84 (6) 49-57 Background E-cigarettes are the most commonly used tobacco product among US youth and are regularly used on school grounds. We assessed school staff’s awareness of students’ e-cigarette use, response by schools, and resources needed to address use, and examined e-cigarettes confiscated by school staff in North Carolina to guide prevention and identify needed resources. methods In May 2019, staff from a random sample of 25 of 451 North Carolina public and charter high schools were invited to complete an online survey and semistructured interview; 12 schools consented to ≥ 1 component (survey, N = 514; interviews, N = 35). Staff knowledge and perceptions of students’ e-cigarette use and school tobacco policies were assessed, including school efforts to address e-cigarette use. E-cigarette products confiscated by nine schools from students during the 2018-2019 school year were collected. limitations Only 12 public high schools participated, and these schools might not be representative of all North Carolina high schools. Quantitative surveys were not collected from all staff at participating schools; however, the response rate was 62% and included different staff positions and both urban and rural schools. Finally, e-cigarette products collected by schools might not be representative of all devices used by students. Results Among surveyed staff, 33% observed students using e-cigarettes on school grounds; 86% believed e-cigarette use somewhat or largely contributes to learning disruptions. Overall, 94% of respondents knew their school’s policy prohibits student e-cigarette use on school grounds, and 57% were not confident their school has resources to help students quit. From 35 interviews, themes included concern that schools’ tobacco-free policies do not deter use and additional resources are needed to address e-cigarette use in schools. Of 336 collected devices, there were different e-cigarette types and most (65%) e-liquid bottles were flavored. conclusion Efforts are warranted to incorporate evidence-based curricula; educate staff, parents, and youth regarding health risks of ecigarette use; and help youth quit e-cigarettes. © 2023 by the North Carolina Institute of Medicine and The Duke Endowment.

Colonization with antibiotic-resistant bacteria in a hospital and associated communities in Guatemala: An Antibiotic Resistance in Communities and Hospitals (ARCH) Study
Ramay BM , Castillo C , Grajeda L , Santos LF , Romero JC , Lopez MR , Gomez A , Caudell M , Smith RM , Styczynski A , Herzig CTA , Bollinger S , Ning MF , Horton J , Omulo S , Palmer GH , Cordon-Rosales C , Call DR . Clin Infect Dis 2023 77 S82-s88 BACKGROUND: We estimated the prevalence of colonization with extended-spectrum cephalosporin-resistant Enterobacterales (ESCrE) and carbapenem-resistant Enterobacterales (CRE) from a hospital and associated communities in western Guatemala. METHODS: Randomly selected infants, children, and adults (<1, 1-17, and ≥18 years, respectively) were enrolled from the hospital (n = 641) during the coronavirus disease 2019 (COVID-19) pandemic, March to September 2021. Community participants were enrolled using a 3-stage cluster design between November 2019 and March 2020 (phase 1, n = 381) and between July 2020 and May 2021 (phase 2, with COVID-19 pandemic restrictions, n = 538). Stool samples were streaked onto selective chromogenic agar, and a Vitek 2 instrument was used to verify ESCrE or CRE classification. Prevalence estimates were weighted to account for sampling design. RESULTS: The prevalence of colonization with ESCrE and CRE was higher among hospital patients compared to community participants (ESCrE: 67% vs 46%, P < .01; CRE: 37% vs 1%, P < .01). Hospital ESCrE colonization was higher for adults (72%) compared with children (65%) and infants (60%) (P < .05). Colonization was higher for adults (50%) than children (40%) in the community (P < .05). There was no difference in ESCrE colonization between phase 1 and 2 (45% and 47%, respectively, P > .05), although reported use of antibiotics among households declined (23% and 7%, respectively, P < .001). CONCLUSIONS: While hospitals remain foci for ESCrE and CRE colonization, consistent with the need for infection control programs, community prevalence of ESCrE in this study was high, potentially adding to colonization pressure and transmission in healthcare settings. Better understanding of transmission dynamics and age-related factors is needed. |

Clin Infect Dis 2020 72 (10) e448-e457 BACKGROUND: The Diamond Princess cruise ship was the site of a large outbreak of coronavirus disease 2019 (COVID-19). Of 437 Americans and their travel companions on the ship, 114 (26%) tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). METHODS: We interviewed 229 American passengers and crew after disembarkation following a ship-based quarantine to identify risk factors for infection and characterize transmission onboard the ship. RESULTS: The attack rate for passengers in single-person cabins or without infected cabinmates was 18% (58/329), compared with 63% (27/43) for those sharing a cabin with an asymptomatic infected cabinmate, and 81% (25/31) for those with a symptomatic infected cabinmate. Whole genome sequences from specimens from passengers who shared cabins clustered together. Of 66 SARS-CoV-2-positive American travelers with complete symptom information, 14 (21%) were asymptomatic while on the ship. Among SARS-CoV-2-positive Americans, 10 (9%) required intensive care, of whom 7 were ≥70 years. CONCLUSION: Our findings highlight the high risk of SARS-CoV-2 transmission on cruise ships. High rates of SARS-CoV-2 positivity in cabinmates of individuals with asymptomatic infections suggest that triage by symptom status in shared quarters is insufficient to halt transmission. A high rate of intensive care unit admission among older individuals complicates the prospect of future cruise travel during the pandemic, given typical cruise passenger demographics. The magnitude and severe outcomes of this outbreak were major factors contributing to the Centers for Disease Control and Prevention's decision to halt cruise ship travel in U.S. waters in March 2020. |
