This study evaluated the impact of roommate and unit mate exposures on coronavirus disease-2019 (COVID-19) transmission to inform isolation practices.Methods: A single-center retrospective study was conducted among patients hospitalized in an inpatient behavioral health hospital from July 2020 through August 2023. We compared the risk of COVID-19 acquisition after exposure among patients with a contagious roommate versus those exposed to a contagious unit mate.Results: During the study period, the conversion rate was 10.05% overall, 24.4% for roommates, and 9.3% for unit mates; patients exposed to a roommate were at 3.14 times higher odds (95% confidence interval, 1.42-6.92) of acquiring COVID-19 after exposure. On unit-stratified analysis, patients exposed to a roommate on the geropsychiatric unit had the highest risk of postexposure conversion compared with unit mate exposed patients (odds ratio 6.38, 95% confidence interval 1.75-23.22). Logistic regression analysis identified a nonsignificant risk associated with increased time in group therapy.Conclusions: Exposure to a COVID-19-contagious roommate significantly increases the risk of COVID-19 acquisition among exposed patients receiving inpatient psychiatric care. Cohorting contagious and exposed individuals and avoiding multibedded rooms may mitigate COVID-19 transmission risk during psychiatric care.","PeriodicalId":7621,"journal":{"name":"American journal of infection control","volume":null,"pages":null},"PeriodicalIF":3.8,"publicationDate":"2024-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142279096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Handwashing practices and swab samples from the hand was collected to evaluate the impact of hand hygiene practices on bacterial load. The Quantitative Microbial Risk Assessment model was used to predict the health risk.Results: The study identified the 2 most common bacteria: Staphylococcus aureus and Escherichia coli. The bacterial contamination was significantly reduced after the intervention (S aureus 166 Colony-forming unit (CFU) /mL and E coli 185 CFU/mL). The higher bacterial ingestion rate was attributed to hand contamination and increased bacteria transfer from hand to mouth.Conclusions: The multicomponent hand hygiene intervention showed improvement in accessibility to hand hygiene resources and practices. The findings underscore the need for hygiene interventions in orphanage schools to improve health and educational outcomes.","PeriodicalId":7621,"journal":{"name":"American journal of infection control","volume":null,"pages":null},"PeriodicalIF":3.8,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142279011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Older adults (65 years and older) are at the highest risk of COVID-19 morbidity and mortality. Analyzing their vaccine uptake by subclassifying demographics is rare and can assist vaccination policies. This study investigates COVID-19 dose 1 and 2 vaccine uptakes among them by race, ethnicity, and sex.Methods: Immunization registry data were used to calculate temporal changes in older adults' COVID-19 vaccine uptake by race, ethnicity, race-sex, and ethnicity-sex in Kentucky's most populous county, Jefferson County, during the first 6 quarters of the COVID-19 vaccination program.Results: By May 2022, the county's Asian residents had the highest dose 1 and 2 vaccination rates (97.0% and 80.4%), then White residents (90.0% and 80.2%). Black residents had one of the lowest COVID-19 vaccination rates (87.3% and 77.3%). The rate among Hispanic residents (82.0% and 66.4%) was considerably lower than non-Hispanic residents (90.2% and 80.1%). The rates were consistently lower in males.Conclusions: Racial, ethnic, and sex-based COVID-19 vaccine inequalities were largely maintained during the study period. Vaccine rollout practices and promotional programs should aim to boost the uptake of the COVID-19 vaccination among racial minority and male older adults.","PeriodicalId":7621,"journal":{"name":"American journal of infection control","volume":null,"pages":null},"PeriodicalIF":3.8,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142279010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Clinical cultures with MRSA from hospitalized patients collected between March 1, 2023, and January 20, 2024 underwent prospective whole-genome sequencing, including assessment for the presence of markers of resistance against mupirocin (mupA) and biocides (qac). Demographic and clinical characteristics were reviewed.Results: We analyzed 463 MRSA isolates. The overall prevalence of mupA(+), qacA(+), and qacC(+) genes was 22.0%, 2.4%, and 19.0%, respectively. Most mupA(+) isolates belonged to ST8, but ST8732 (a novel variant of ST8) had the highest prevalence of mupA(+) isolates at 95%. Patients mupA(+) were older, and none of the isolates from pediatric patients harbored this gene.Discussion: Through prospective whole-genome sequencing of MRSA isolates, we detected a prevalence of genes conferring mupirocin resistance considerably higher than previously reported, particularly among MRSA ST8 variants.Conclusions: Our findings highlight the need for monitoring resistance to agents used for the prevention of S aureus infections, as these trends have implications for infection prevention programs and public health at large.","PeriodicalId":7621,"journal":{"name":"American journal of infection control","volume":null,"pages":null},"PeriodicalIF":3.8,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142279013","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study proposes improvements to the TNPI ward to prepare for airborne infections.Methods: Existing air-conditioning systems were investigated during the pandemic in 4 hospitals through a document review and field investigation with staff interviews. On-site experiments and measurements were conducted under vacant conditions. Differential pressure (∆P) between spaces was measured in all 4 hospitals, while tracer gas tests were carried out in 2 hospitals.Results: The investigation revealed that thermal discomfort caused the existing systems remaining perpetually active. Additionally, the noise generated by the PHU caused an unexpected shutdown of that equipment. Furthermore, the ∆P of over -2.5 Pa was measured as a result of the operating status of equipment. These situations can cause duct backflow and gas diffusion through unsealed diffusers. Moreover, low airtightness of existing facilities can affect indoor environment, pressure difference, and gas diffusion.Conclusions: When using existing facilities as TNPI wards, the airtightness and existing systems should be considered. We concluded that it is important to increase the airtightness and seal unused diffusers in order to prevent cross-infection by unpredictable airflow.","PeriodicalId":7621,"journal":{"name":"American journal of infection control","volume":null,"pages":null},"PeriodicalIF":3.8,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142153045","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
