The objective of this paper is to reflect on the potential of using prevalence and excretion rate data from the literature to simulate wastewater concentrations for norovirus and rotavirus. Three systematic literature reviews were carried out to collect worldwide data. Firstly, targeting community-level prevalence data, secondly, viral excretion rates in faecal material, and thirdly, concentrations in wastewater. Data collected in the first two reviews were input to simulate concentrations in wastewater. Model results were compared with reported concentrations collected in the latest review. Of 2,193 studies, 97 were included. Reported community-level prevalence of infection ranged from 0.22 to 9.5% for norovirus and 0 to 3.3% for rotavirus. Mean viral excretion was 4.9 × 1010 and 9.7 × 108 GC/g stool for norovirus and rotavirus, respectively. Average reported wastewater concentrations were 1.5 × 107 and 2.4 × 107 GC/100 mL, respectively. Modelled concentrations were generally higher than observed values. This synthesis demonstrates the potential of integrating prevalence and excretion data through modelling to estimate pathogen loads in wastewater while highlighting major sources of variability and the need for more data collection on prevalence and excretion.","PeriodicalId":17436,"journal":{"name":"Journal of water and health","volume":"24 3","pages":"415-431"},"PeriodicalIF":2.4,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147574795","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}

In this study, we implemented a year-round wastewater surveillance program in a great metropolitan area of Costa Rica to assess its feasibility and epidemiological utility. Four major enteric viruses: rotavirus (RoV), norovirus genogroups I (NVG1) and II (NVG2), and pan-enterovirus (PEV), were quantified by RT-qPCR in the effluent of the country's main wastewater treatment plant. Weighted Quantile Sum regression was applied to compare the mixture of viruses detected with reported diarrhoea cases during the study period (June 2023- July 2024). NVG2 was the most frequently detected virus, while RoV and PEV peaked during the rainy season. The WQS mixture index showed no significant association with weekly case counts at any lag (RR 0.928-1.091; all p > 0.05). Component weights varied by model, and the rainy season was the only factor significantly associated with higher case counts (RR = 1.42, p = 0.012).

This study examined water quality variations across four remote barangays in Barbaza, Antique, Philippines, and investigated contributing geographic and demographic factors.

Significant differences in EC and TDS (p < 0.01) were observed, with Binangbang Centro, a barangay relying primarily on groundwater, showing the highest median values. E. coli was detected in 23.1% of well water samples, while coliform exceeded standards (<1 colony/100 mL) in up to 100% of tap and drinking water samples. Despite widespread reliance on refilling stations, over 70% of drinking water samples contained coliform, possibly associated with post-purchase handling and storage conditions. Gua, the most densely populated barangay, recorded the highest coliform levels in drinking water (median: 102 CFU/mL). The findings highlight the need for barangay-specific strategies combining infrastructure improvements, decentralized monitoring, and hygiene education.

This cross-sectional study aimed to detect and characterize rotavirus in samples collected from three wastewater treatment plants in Morogoro, Tanzania to monitor RVA circulation. A total of 189 grab samples were collected weekly between November 2024 and February 2025. Samples were pooled by site, yielding 93 pooled samples, and processed for RVA detection using reverse transcription polymerase chain reaction (RT-PCR) targeting VP4 and VP7 genes, followed by Sanger sequencing and phylogenetic analysis. RVA was detected in 8.6% (n=93) of the pooled samples: 16.1% in Mafisa, 9.7% in Mzumbe, and 0% in Magadu (p=0.074). Genotyping identified G3 and P [8] as predominant RVA genotypes, clustering within lineage III and showing ≥97.5% nucleotide identity with known RVA strains.

This study assessed socioecological drivers and dimensions as determinants of water insecurity among 434 adults with HIV receiving care in public hospitals in a high HIV prevalence region of western Kenya. We used the 12-item Household Water Insecurity Experiences Scale and found a water insecurity prevalence of 64.3% among participants, with 22.4% having severe water insecurity (score ≥24). Drought (96.8%), poverty (90.3%), and poor infrastructure (90.1%) were frequently cited drivers, while affordability (82.4%), flooding (85.4%), and microbial contamination (75.7%) were common dimensions. Female participants had nearly four-fold higher odds of water insecurity (AOR = 3.65, 95% CI: 2.02-6.58), and temporary housing structures (AOR = 3.10, 95% CI: 1.75-5.51) and larger households (AOR = 1.23 per additional person, 95% CI: 1.09-1.39) further increased vulnerability.

We hypothesized that combining wastewater and environmental covariates in a dual-branch deep model leveraging FFT would improve forecasting and alerting.Methods: Using weekly wastewater, meteorological, and case data from Changzhou, China (Jan 29-Dec 10, 2024), we developed a framework that forecasts case trajectories and triggers tiered yellow/red alerts at predefined thresholds.Results: On 2-week-ahead internal tests, performance was: RMSE 1.40 (1.13-1.67), MAE 1.23 (0.99-1.48), MAPE 10.44% (5.20-16.40), and R2 0.99 (0.99-0.99). On an external test, both yellow and red alerts were correctly predicted 3 weeks ahead. Versus a naive baseline and the COVID-19 Forecast Hub model, our approach reduced missed alerts, whereas the Forecast Hub model reduced false declarations. Ablation showed necessity of the dual-branch architecture and covariates.Conclusions: The novel framework delivers accurate, timely forecasts and reliable early warnings from multi-source data, supporting proactive public health response to COVID-19. It may also be a promising approach for the prediction of other infectious diseases. However, validating and adapting the approach across locations, and epidemic patterns is a key next step to establish robustness, generalizability, and operational value.","PeriodicalId":17436,"journal":{"name":"Journal of water and health","volume":"24 3","pages":"349-366"},"PeriodicalIF":2.4,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147574826","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 results show that the ionic dominance sequence is Na+ > Ca2+ > Mg2+ > K+ for cations and HCO3- > SO42- > Cl- for anions. Water-rock interactions - including dissolution of halite, gypsum, and dolomite - dominate groundwater chemical evolution. However, in northern aquifers, evaporative concentration and anthropogenic pollution are prominent, as indicated by significant correlations among Cl-, NO3-, and TDS. According to the entropy-weighted TOPSIS assessment, 22% of samples were classified as poor to extremely poor quality (C = 0.004-0.359), mainly distributed in Fuping and Pucheng counties due to elevated levels of TH, TDS, Na+, SO42-, Cl-, and F-. The Nitrate Pollution Index results further reveal that 25% of samples experience moderate to extreme pollution, with significantly higher levels in the northern part of the basin.
