Risk assessment of waterborne viruses for recreational sites in Lake Geneva

Abstract

Norovirus is the most acute species among the viruses studied according to the simulations while enterovirus poses the least danger. The relative distance to the contamination sources, wind conditions as well as inactivation rates are essential in determining virus concentrations at a specific site in lakes. Comprehensive studies including QMRA are necessary for risks evaluation. Stochastic simulations can indicate uncertainties in risk assessment. More information on the sewage virus concentration would be important to capture the seasonality of virus contamination.

Risk assessment

Risk assessment determines possible mishaps, their likelihood and consequences, and the tolerances for such events. The results of this process may be expressed in a quantitative or qualitative fashion. Risk assessment is an inherent part of a broader risk management strategy to help reduce any potential risk-related consequences. More precisely, risk assessment identifies and analyses potential (future) events that may negatively impact individuals, assets, and/or the environment (i.e. hazard analysis).

Risk management

Risk management is the identification, evaluation, and prioritization of risks (defined in ISO 31000 as the effect of uncertainty on objectives) followed by coordinated and economical application of resources to minimize, monitor, and control the probability or impact of unfortunate events or to maximize the realization of opportunities.

Virus

A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. Since Dmitri Ivanovsky's 1892 article describing a non-bacterial pathogen infecting tobacco plants and the discovery of the tobacco mosaic virus by Martinus Beijerinck in 1898, more than 11,000 of the millions of virus species have been described in detail.
