Abstract
As the coronavirus disease 2019 continues to spread globally, its culprit, the severe acute respiratory syndrome coronavirus 2 has been brought under scrutiny. In addition to inhalation transmission, the possible fecal-oral viral transmission via water/wastewater has also been brought under the spotlight, necessitating a timely global review on the current knowledge about waterborne viruses in drinking water treatment system - the very barrier that intercepts waterborne pathogens to terminal water users. In this article we reviewed the occurrence, concentration methods, and control strategies, also, treatment performance on waterborne viruses during drinking water treatment were summarized. Additionally, we emphasized the potential of applying the quantitative microbial risk assessment to guide drinking water treatment to mitigate the viral exposure risks, especially when the unregulated novel viral pathogens are of concern. This review paves road for better control of viruses at drinking water treatment plants to protect public health.

Phenotypic characterization of cell culture-derived hepatitis E virus subjected to different chemical treatments: Application in virus removal via nanofiltration. J Virol Methods 2021; 296:114244. [PMID: 34302862 DOI: 10.1016/j.jviromet.2021.114244] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2021] [Revised: 07/15/2021] [Accepted: 07/16/2021] [Indexed: 12/23/2022]
Abstract
Safety evaluation for the hepatitis E virus (HEV) is required for plasma fractionation products. Plasma-derived HEV (pHEV) is quite unique in that it is associated with a lipid membrane, which, when stripped during manufacturing processes, induces morphological changes in the virus, making it difficult to select proper HEV phenotypes for clearance studies. We developed a convenient system for the preparation of a high titer cell culture-derived HEV (cHEV). In this system, PLC/PRF/5 cells transfected with the wild-type HEV genome generated lipid membrane-associated cHEV for a long period even after cryopreservation. We also examined how this lipid membrane-associated cHEV can be used to verify the robustness of pHEV removal via 19-nm nanofiltration. Sodium-deoxycholate and trypsin (NaDOC/T) treatment not only dissolved lipid but also digested membrane-associated proteins from pHEV and cHEV, making the resulting cHEV particle smaller in size than any pHEV phenotypes generated by ethanol or solvent-detergent treatment in this study. In both 19-nm and 35-nm nanofiltration, cHEV behaved identically to pHEV. These results indicate that cHEV is a useful resource for viral clearance studies in term of availability, and the use of NaDOC/T-treated cHEV ensured robust pHEV removal capacity via 19-nm nanofiltration.
