Numerical simulation of the fate, transport and public health risks of enteric viruses in Lake Geneva
Lakes are a fundamental feature of nature with brilliance, profoundness and complexity. Various of physical, chemical and biological changes take place three dimensionally in deep lakes, regulated by complicated boundary conditions. To understand and predi ...
EPFL2023Simultaneous membrane and RNA binding by Tick-Borne Encephalitis Virus capsid protein
Tick-borne encephalitis virus is an enveloped, pathogenic, RNA virus in the family Flaviviridae, genus Flavivirus. Viral particles are formed when the nucleocapsid, consisting of an RNA genome and multiple copies of the capsid protein, buds through the end ...
PUBLIC LIBRARY SCIENCE2023Risk assessment of waterborne virus in Lake Geneva: the present and the future
The presence of waterborne enteric viruses in lake recreational water sites is not desired, as they may have a negative impact on human health. However, their concentrations, fate and transport in lakes remain poor understood. To date, the health risks pos ...
2023Toward biocontrol of waterborne pathogens: contributions of protists to virus removal and associated mechanisms
Human viruses are widespread in the water environment and pose a risk to human health. Wastewater effluents represent the main source of viruses discharge in the environment, leading to contamination of aquatic ecosystems. Viral pathogens can persist on th ...
EPFL2022Expiratory Aerosol pH: The Overlooked Driver of Airborne Virus Inactivation
Athanasios Nenes, Tamar Kohn, Kalliopi Violaki, Ghislain Gilles Jean-Michel Motos, Aline Laetitia Schaub, Shannon Christa David, Walter Hugentobler
Respiratory viruses, including influenza virus and SARS-CoV-2, are transmitted by the airborne route. Air filtration and ventilation mechanically reduce the concentration of airborne viruses and are necessary tools for disease mitigation. However, they ign ...
2022Pretreatment options for micropollutant abatement before aquifer recharge in drinking water production: Assessment of UV/H2O2 and dense membranes
Micropollutants (MP) such as residues of pharmaceuticals, industrial chemicals or pesticides can be detected in almost all water resources. Various processes can be used to abate them in drinking water treatment, e.g., ozonation, advanced oxidation process ...
EPFL2022Waterborne virus transport and the associated risks in a large lake
Tamar Kohn, Xavier Fernandez Cassi, Chaojie Li, Timothy R. Julian
Waterborne enteric viruses in lakes, especially at recreational water sites, may have a negative impact on human health. However, their fate and transport in lakes are poorly understood. In this study, we propose a coupled water quality and quantitative mi ...
2022Control of Waterborne Human Viruses by Indigenous Bacteria and Protists Is Influenced by Temperature, Virus Type, and Microbial Species
Tamar Kohn, Anna Carratala Ripolles, Margot Ninon Lauren Olive
Human viruses are ubiquitous contaminants in surface waters, where they can persist over extended periods of time. Among the factors governing their environmental persistence, the control (removal or inactivation) by microorganisms remains poorly understoo ...
2020Adaptation of Human Enterovirus to Warm Environments Leads to Resistance against Chlorine Disinfection
Tamar Kohn, Anna Carratala Ripolles, Virginie Bachmann, Timothy R. Julian
Sunlight, temperature, and microbial grazing are among the environmental factors promoting the inactivation of viral pathogens in surface waters. Globally, these factors vary across time and space. The persistence of viral pathogens, and ultimately their e ...
2020Sulfonated Nanomaterials with Broad-Spectrum Antiviral Activity Extending beyond Heparan Sulfate-Dependent Viruses
Francesco Stellacci, Matteo Gasbarri, Valeria Cagno, Chiara Medaglia
Viral infections are among the main causes of death worldwide, and we lack antivirals for the majority of viruses. Heparin-like sulfated or sulfonated compounds have been known for decades for their ability to prevent infection by heparan sulfate proteogly ...
