Multiple environmental, social, and economic determinants jointly influence disease transmission, operating through interconnected pathways within this system. However, the causal mechanisms linking these determinants to infectious disease outcomes remain poorly understood. This study systematically reviews and synthesizes evidence on the causal interrelationships among key determinants to better elucidate their contributions to infectious disease incidence. Drawing on literature across urbanization, climate change, land-use change, population mobility, and water, sanitation, and hygiene (WaSH) conditions, we examine how these factors interact to influence transmission dynamics through complex environmental and socioeconomic pathways. Our findings indicate that no single determinant independently drives disease transmission; rather, overlapping exposures and interactions create complex feedback loops that amplify public health vulnerabilities, particularly in resource-constrained settings. We advocate for the integration of causal inference to move beyond traditional correlation-based analyses and to identify the pathways through which these determinants influence disease dynamics. Embedding causal reasoning within the One Health framework can strengthen evidence-based policy and support the design of targeted, context-specific, and resilient public health interventions aimed at reducing the burden of infectious diseases.","PeriodicalId":17436,"journal":{"name":"Journal of water and health","volume":"24 6","pages":"759-772"},"PeriodicalIF":2.4,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148361265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The integration of electrical and automation-related risks into Water Safety Plan (WSP) assessments remains methodologically underdeveloped, despite their critical role in system reliability and process control. This study proposes a semi-quantitative framework to incorporate such risks into WSP processes through structured checklists and a rule-based probability-severity scoring approach. The methodology was applied to the Negrisiola drinking water supply system in Northern Italy. Thirteen risk scenarios were assessed, resulting in two high-risk cases (R = 12), two medium-risk cases (R = 6 and R = 9), and the remaining scenarios classified as low risk. The analysis shows that risk is predominantly driven by severity rather than probability, reflecting the low-frequency but high-impact nature of infrastructure-related failures. A power outage event observed during the study period, associated with a reduction in free chlorine concentration, provides illustrative evidence consistent with the identified failure pathways. Although no causal relationship can be definitively established, this observation supports the plausibility of the proposed risk mechanisms. The results demonstrate that electrical and automation systems should be considered integral components of water safety management. The proposed framework provides a practical and reproducible tool to enhance the integration of operational risks into WSPs and support risk prioritisation. Further research should focus on strengthening empirical validation through the integration of operational and analytical datasets.","PeriodicalId":17436,"journal":{"name":"Journal of water and health","volume":"24 6","pages":"784-799"},"PeriodicalIF":2.4,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148361415","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specific pollutant loads were calculated for biochemical oxygen demand, chemical oxygen demand, total nitrogen, ammonium nitrogen, total phosphorus, and orthophosphate. Overall, pollutant loads remained stable during the study period, though an increase was observed in recent years, with ammonium rising by 27%, total nitrogen by 15%, and phosphorus by 11%. Industrial plants consistently showed higher pollutant loads than municipal facilities. Nitrogen exhibited the lowest variability among the evaluated hydrochemical parameters, suggesting its suitability as a robust normalization indicator within the studied dataset, while chemical oxygen demand can serve as a supporting indicator. In contrast, biochemical oxygen demand and phosphorus were less suitable due to operational sensitivity and high variability. The study recommends using rolling, plant-specific median values over two to three years to enhance the precision and comparability of population-normalized wastewater-based health assessments.","PeriodicalId":17436,"journal":{"name":"Journal of water and health","volume":"24 6","pages":"830-843"},"PeriodicalIF":2.4,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148361125","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study evaluates the impact of a single norovirus outbreak on wastewater measurements in a community. Norovirus genogroup 2 (GII) concentrations were measured at two wastewater treatment facilities (WWTFs) near a restaurant experiencing a norovirus GII outbreak (Restaurant A). The largest increase in norovirus GII RNA concentrations (increase of 13,111.8 gc/mL) at the WWTF serving Restaurant A (WWTF A) occurred on the same day most (44%) outbreak case patients reported symptom onset. This increase occurred 1 day before the outbreak was reported to public health, 2 days before norovirus was identified in clinical specimens, and 3 days before clinical specimens were genotyped at the public health laboratory. At a second local WWTF, WWTF B, norovirus GII RNA concentrations also increased at the same time but peaked 2 days after WWTF A. These findings suggest wastewater measurements can serve as a leading indicator of norovirus outbreaks and inform outbreak response efforts.","PeriodicalId":17436,"journal":{"name":"Journal of water and health","volume":"24 6","pages":"887-895"},"PeriodicalIF":2.4,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148361336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It includes analysis of the National Water, Sanitation, and Hygiene survey (n = 628) and latrine swab samples (n = 91) from eight latrines. E. coli densities on latrine surfaces were significantly associated with flush types, latrine location, and visible moisture and dirt. Households reporting diarrhoea had significantly higher E. coli on latrine surfaces (2.6 × 102 CFU/25 cm2) than those without (12.3 CFU/25 cm2) (p < 0.001), suggesting a possible diarrhoeal transmission pathway. It also highlights the potential risk of urinary tract infections, specifically for women from faecally contaminated anal cleansing water.
