The Advisory Committee on Immunization Practices recommends routine annual seasonal influenza vaccination for persons without contraindications, including HCP and those at increased risk for severe influenza. Nursing homes report influenza vaccination among residents and HCP to CDC's National Healthcare Safety Network. This report describes influenza vaccination coverage among nursing home residents and HCP working in nursing homes during the 2024-25 influenza season (October 1, 2024-March 31, 2025). At the end of the 2024-25 influenza season, influenza vaccination coverage was 61.3% among nursing home residents and 42.1% among HCP who work in nursing homes; coverage among HCP varied by employment type. This study is the first comprehensive, national assessment of influenza vaccination coverage among nursing home residents and HCP who work in nursing homes in the United States. Monitoring of influenza vaccination coverage in this population at high risk for influenza exposure and severe influenza disease, along with implementation of a combination of influenza vaccination, administration of influenza antiviral medications, and other recommended practices to control the spread and severity of influenza in nursing home settings, can help protect nursing home residents and HCP against severe influenza-associated outcomes.","PeriodicalId":18931,"journal":{"name":"Morbidity and Mortality Weekly Report","volume":"32 1","pages":"195-201"},"PeriodicalIF":0.0,"publicationDate":"2026-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147735379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Shigella infection is spread through fecal-oral transmission and sexual contact. Although most infections are self-limited, antibiotics are indicated for severe illness or to reduce transmission in settings with high risk for spread. Since 2015, a growing proportion of cases has been caused by extensively drug-resistant (XDR) Shigella species, defined as being resistant to ampicillin, azithromycin, ceftriaxone, ciprofloxacin, and trimethoprim-sulfamethoxazole. No Food and Drug Administration-approved oral antimicrobial agents are available to treat these XDR infections. To describe U.S. trends and epidemiologic characteristics of XDR shigellosis, CDC analyzed Shigella isolates submitted to PulseNet, CDC's molecular surveillance network for enteric pathogens, during January 1, 2011-October 20, 2023; antimicrobial resistance was characterized using whole-genome sequencing data and antimicrobial susceptibility testing. Among 16,788 isolates with resistance data during this period, 510 (3.0%) were XDR. The percentage of XDR isolates increased from 0% during 2011-2015 to 8.5% in 2023.

Diamond Shruumz microdosing chocolate bars are edible products designed so that small doses of mushroom-derived psychoactive compounds and other psychoactive ingredients can be eaten in a presectioned serving. In response to this alert, CDC and the Food and Drug Administration coordinated a nationwide outbreak investigation to characterize the potential poisonings associated with eating Diamond Shruumz microdosing chocolate bars. A case of poisoning was defined as an illness with moderate or major clinical effects (i.e., symptoms) as defined by America's Poison Centers in a person who ate any Diamond Shruumz product or another mushroom-containing chocolate product during January-October 2024. In total, 180 cases were reported in 34 states. Among these, 73 persons were hospitalized, including 38 persons who required intensive care unit (ICU) admission, 29 who required endotracheal intubation, and two deaths. Eating Diamond Shruumz chocolate bars was associated with higher odds of hospitalization (odds ratio [OR] = 3.29; 95% CI = 1.51-7.40), ICU admission (OR = 6.30; 95% CI = 2.17-22.6), seizures (OR = 8.45; 95% CI = 3.00-27.9), and endotracheal intubation (OR = 8.04; 95% CI = 2.24-44.2), compared with eating other mushroom-containing chocolate products. Eating larger amounts of Diamond Shruumz chocolate bars was associated with an increased likelihood of hospitalization, ICU admission, and endotracheal intubation (p-value for trend tests [p-trend] = 0.023, 0.004, and <0.001, respectively). Diamond Shruumz products were recalled, and the public was advised not to eat, sell, or serve any Diamond Shruumz products and to discard any Diamond Shruumz products previously purchased. Testing of some Diamond Shruumz products identified substances present in psychoactive mushrooms, including muscimol, psilocin (a Schedule I controlled substance), kavalactones, and other substances in some, but not all, tested products. Consumers should be aware of the poisoning risk associated with eating Diamond Shruumz products and other mushroom-containing microdosing chocolate products due to variability in ingredient composition, the absence of standardized regulatory oversight for sampling and testing finished products, and the potential toxicity of compounds intended to produce psychoactive effects.","PeriodicalId":18931,"journal":{"name":"Morbidity and Mortality Weekly Report","volume":"62 1","pages":"179-184"},"PeriodicalIF":0.0,"publicationDate":"2026-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147641504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the United States, kava emerged in the late 1990s and has experienced renewed growth and product diversification since the 2010s, with increasing availability of concentrated extracts and ready-to-drink beverages. These commercial products are commonly marketed as healthy alternatives to alcohol, sold near college campuses, and increasingly being combined with kratom, a psychoactive botanical with opioid-like effects, raising safety concerns. Data on kava-related use during January 2000-December 2025 that resulted in a report to the National Poison Data System (i.e., kava exposure report) were analyzed to assess trends by users' demographic characteristics, exposure type, and outcomes. Kava-related exposure reports declined sharply after a 2002 Food and Drug Administration advisory on kava-associated severe liver injury but have risen steadily since 2011, reaching 203 reported exposures in 2025. Reports primarily involved adults aged ≥20 years, but demographic characteristics have changed over time. During 2000-2001, reports primarily involved females and included more children aged ≤12 years, whereas exposure reports since 2013 have predominantly involved men; reports involving children have been rare. Since 2017, reports involving combined use of kava and kratom have increased, reaching 30% (61) of all kava reports in 2025. These increases have coincided with higher rates of serious reported clinical outcomes in recent years (32% in 2025 compared with 12% in 2000). These data indicate a resurgence of overall kava exposure reports to poison centers, as well as an increase in kratom-related kava reports, which has coincided with higher rates of serious clinical outcomes. The findings in this report suggest the need for enhanced surveillance for, clinical awareness of, and public education regarding commercial products containing kava.","PeriodicalId":18931,"journal":{"name":"Morbidity and Mortality Weekly Report","volume":"4 1","pages":"157-163"},"PeriodicalIF":0.0,"publicationDate":"2026-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147599503","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Kratom contains psychoactive compounds that interact with opioid receptors and is widely available in various forms in the United States. Its evolution from natural leaf to high-potency alkaloid products has raised concerns about toxicity. Data on kratom-related use that resulted in a report to the National Poison Data System (NPDS) (i.e., kratom exposure report) during 2015-2025 were analyzed to assess trends by exposure report type, demographic characteristics of persons exposed, and outcomes. During the past 11 years, poison centers received a total of 14,449 kratom exposure reports; the record high 3,434 reports in 2025 represent an increase of approximately 1,200% compared with the 258 reports in 2015. Most reports involved males and young adults aged 20-39 years, but reports among adults aged 40-59 years increased most sharply, with rates nearly overlapping with those among young adults by 2025. Although single-substance exposure reports accounted for most reports (62%), multiple-substance reports occurred at higher rates (range = 467-5,442 per 1 million multiple-substance drug exposure reports versus 388-4,045 per 1 million single-substance drug exposure reports), were associated with more hospitalizations (44%-56% versus 24%-29% annually) and serious (life threatening, pronounced, prolonged, or systemic) outcomes (57%-66% versus 41%-49% annually), and accounted for the vast majority of kratom-associated deaths during the study period (184 of 233; 79%).
