Exploratory factor analysis identified three dietary patterns: Western-style, traditional Korean, and seafood-rich.

Enhancing the safety of these services increases costs, yet affordability for customers is essential. Thus, reducing service costs is a key priority. Group-based approach, where emptiers visit multiple toilets consecutively, has potential to improve both service efficiency and affordability. However, few studies have investigated its applicability to manual emptying. This paper aims to identify barriers and enablers for group-based manual emptying services in low-income neighbourhoods of Nairobi. We conducted 12 focus group discussions with landlords, tenants, and manual emptiers in the Korogocho informal settlement in Nairobi and interviewed 20 key informants from relevant sectors in Kenya. We identified five categories of barriers and enablers that affected general and group-based manual emptying: 1) funding, 2) expertise and equipment, 3) social and commercial habits, 4) physical conditions, and 5) regulatory systems. Of these, a norm that pits are not emptied until they get full, operating time constraints, fair and transparent pricing, and an organiser who can arrange group-based emptying from Category 3, and transport capacity from Category 4 specifically affected group-based manual emptying. Given that the barriers have a cascade structure, addressing some primary barriers such as capacity building and recognising manual emptiers’ role in the sanitation policies could be effective ways to ensure safe and affordable emptying services.</div></div>","PeriodicalId":13994,"journal":{"name":"International journal of hygiene and environmental health","volume":"267 ","pages":"Article 114595"},"PeriodicalIF":4.5,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144070950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study evaluates viral spread and infection risks in a hotel lobby and assesses the efficacy of a Targeted Hygiene intervention designed to reduce contamination while minimizing excessive chemical use. A viral tracer study, using bacteriophage Phi X174, and human behavior observations were utilized to monitor surface contamination patterns, followed by Quantitative Microbial Risk Assessment (QMRA) to estimate infection probabilities. Tracer organisms seeded on high-touch surfaces spread to 50 % of sampled fomites within 4 h.

The proportion of cross-contaminated surfaces (i.e., non-seeded sites testing positive) decreased from 13 % to 2 %, and the overall percentage of positive surfaces dropped from 50 % to 42 %.
