[Viral pollution of drinking water in industrial towns of Eastern Siberia].

The drinking water was tested for viruses in the industrial towns of Eastern Siberia. The findings suggest that extremely poor provision with good quality drinking water is seen in the town of Ust-Ilimsk where there were high levels of pathogenic viruses in the water. The high contamination of drinking water with hepatitis A virus and rotavirus is a cause of higher incidence of intestinal viral infections in the areas under study.
