Assessing the health risk of virus-contaminated water should take account of virus inactivation due to environmental stressors, a new study shows. Viruses that cause stomach bugs can be present in lakes, including those used for recreation. However, viral contamination of recreational waters is rarely directly monitored and how viruses behave in lake water is poorly understood. Researchers therefore looked to assess the risk from four common waterborne viruses in Lake Geneva: adenovirus, enterovirus, norovirus and rotavirus. Click here to read more
