In 2019, cases were concentrated in Ribeira Valley, in the southeast region of Brazil, and largely affected rural Quilombola communities, which can trace their origins to escaped, freed, or abandoned slaves in the mid-1800s, and which traditionally practice subsistence agriculture. We aimed to explore aspects of the YF outbreak and vaccination from the perspective of the Quilombola communities. This was a cross-sectional descriptive study conducted in two Quilombola communities in Ribeira Valley (Sapatu and Nhunguara), using an interviewer-administered questionnaire that included both closed and open-ended questions. Thematic reflective analysis principles were applied for qualitative analysis. We adopted a theoretical domains framework to identify and categorize reported facilitators and barriers to YF vaccination. A total of 226 participants were enrolled: 46% male, median age 44 years. Eighty participants reported acute illness during the outbreak; fever, headache, myalgia, and nausea were the most common symptoms. Only eight participants reported laboratory-confirmed YF. Almost all participants (96.5%) reported YF vaccination. Less than two-thirds of the participants were vaccinated before the first case in the Ribeira Valley; over a third were vaccinated after the death of a community leader. The themes were: concerns about the vaccine, difficulty in accessing healthcare, perception of disease risk, knowledge about disease severity, cultural beliefs, and influence of leaders. The outbreak in the Ribeira Valley may have been averted with an understanding of the vaccination decision-making process, influenced by individual, sociocultural, and contextual factors.</p>","PeriodicalId":7752,"journal":{"name":"American Journal of Tropical Medicine and Hygiene","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143762811","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Invasive non-typhoidal Salmonella isolates archived over 5 years from febrile patients at a local health center were characterized for serotypes and antimicrobial susceptibility patterns using conventional methods. Among the 80 archived isolates, 18 serotypes of invasive non-typhoidal Salmonella were identified, with Salmonella Typhimurium (42.5%), Salmonella Enteritidis (20%), and Salmonella Haifa (8.8%) being the most prevalent. A total of 81.3% (65/80) of the isolates exhibited resistance to at least one antibiotic, with the highest resistance rates observed for streptomycin (72.5%), trimethoprim-sulfamethoxazole (66.2%), and ampicillin (56.2%). The most common antimicrobial resistance profile, found in 23.1% (15/65) of resistant isolates, was Amp-C-S10-S300-SXT. Notably, 81.5% of the drug-resistant isolates were multi-drug resistant.

This study has assessed the prevalence of HPV infection, identified the most common HPV genotypes, and evaluated their correlation with cervical lesions at the University Teaching Hospital of Kigali, Rwanda. A total of 473 women were screened for HPV infection, with further evaluation of cervical lesions in HPV-positive women. The overall HPV prevalence was 74 of 473 (15.6%), with the highest concentration among women aged 41-45 years (29.7%). HPV genotypes 16 and 18 were most prevalent (7.6% each). Cyto-histological examination showed 23.6% cancerous lesions and 37.2% benign lesions in women with HPV-positive results. Women with high-risk HPV (HR-HPV) infections had a 2.67-fold increased risk of developing cancerous lesions compared with those with low-risk HPV infections (95% CI: 1.08-6.58, P = 0.033). Notably, 21.6% of HPV-positive women were also HIV-positive, highlighting the coinfection of these two viruses. In conclusion, this study demonstrates a varied distribution of HPV genotypes among Rwandan women and a significant association between HR-HPV types and cervical lesions.
