Wastewater treatment plants employ a range of processes to reduce microbial contamination, with membrane filtration emerging as a promising solution due to its ability to physically remove pathogens without the production of harmful chemical by-products. This study investigates the effectiveness of a gravity-driven membrane (GDM) filtration system for pathogen removal from wastewater and evaluates the associated public health risks with and without treatment. A quantitative microbial risk assessment model was employed to estimate infection probabilities for various waterborne pathogens. The results demonstrated a significant decrease in pathogen concentrations following treatment, with up to a 10<sup>4</sup>-fold reduction in norovirus infection risk. Three critical factors influencing membrane performance were identified: membrane integrity, pore size characteristics, and membrane fouling. Maintaining membrane integrity was found to be essential for ensuring consistent pathogen removal. While nominal pore size is commonly used to predict rejection efficiency, the overall pore size distribution was found to have a greater influence on virus retention. Additionally, although membrane fouling is often considered detrimental, it was shown to enhance virus removal by up to two orders of magnitude. These findings underscore the potential of GDM systems for effective virus removal and highlight the importance of proper membrane design, maintenance, and monitoring in ensuring long-term operational efficiency and maximizing public health protection in wastewater treatment applications.</p>","PeriodicalId":563,"journal":{"name":"Food and Environmental Virology","volume":"17 3","pages":"40"},"PeriodicalIF":4.1,"publicationDate":"2025-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12259810/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144635857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, we further verified the performance of the HEV RT-PCR assay using the WHO International Standard and Reference Panel for HEV RNA. Finally, we assessed different combinations of RNA concentration protocols and RT-PCR detection strategies. This showed that isopropanol precipitation of viral RNA was at least twice as efficient as magnetic silica bead-based extraction when an inhibitor-tolerant RT-qPCR detection strategy was used.

{"title":"Quantification and Genotyping of Norovirus in Aerosols from Wastewater Treatment Plants in Thailand","authors":"Leera Kittigul,&nbsp;Kitwadee Rupprom,&nbsp;Yuwanda Thongpanich,&nbsp;Thanakrit Neamhom,&nbsp;Fuangfa Utrarachkij","doi":"10.1007/s12560-025-09647-1","DOIUrl":"10.1007/s12560-025-09647-1","url":null,"abstract":"<div><p>Norovirus and rotavirus are the major causes of acute gastroenteritis in humans worldwide. Due to their small size, these enteric viruses present in wastewater become aerosolized. The objective of this study was to assess the presence and concentrations of norovirus and rotavirus in aerosol samples collected from wastewater treatment plants (WWTPs) in Thailand. A developed method for concentrating viruses and performing molecular detection was used to determine naturally occurring enteric viruses. Of the 24 collected aerosol samples, 8 (33.3%) and 2 (8.3%) tested positive for norovirus RNA using RT-qPCR and RT-nested PCR, respectively. Based on RT-qPCR, norovirus GII RNA was detected more frequently in aerosol samples (7/24, 29.2%) compared to norovirus GI RNA (2/24, 8.3%). The norovirus GI concentrations were 9.8 × 10<sup>2</sup> and 3.2 × 10<sup>3</sup> genome copies/m<sup>3</sup>. The norovirus GII concentrations ranged from 1.5 × 10<sup>2</sup> to 5.5 × 10<sup>3</sup> genome copies/m<sup>3</sup>. RT-nested PCR detected norovirus GII RNA and the rare GII.21 norovirus strains were identified in the two aerosol samples. However, rotavirus RNA was not detected in any of the aerosol samples using either RT-qPCR or RT-nested PCR. This study highlights the quantification and genotyping of norovirus in aerosol samples generated from wastewater, suggesting a potential effect of airborne transmission for WWTPs workers.</p></div>","PeriodicalId":563,"journal":{"name":"Food and Environmental Virology","volume":"17 2","pages":""},"PeriodicalIF":4.1,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12560-025-09647-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144125582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
