[Evaluation of intestinal viral contamination of water objects as compared to morbidity trends]. / Otsenka kontaminatsii vodnykh ob"ektov kishechnymi virusami v sopostavlenii s dinamikoi zabolevaemosti naseleniia.

The 1988-2000 laboratory studies of water objects in the Perm Region revealed a significant contamination of household effluents, underground and superficial water sources and distribution network water with hepatitis A antigen, Coxsackie and ECHO enteroviruses, and rotavirus antigen. A decrease in the contamination of distribution network water with hepatitis A antigen and an increase in its contamination with rotavirus antigen in recent years coincide with the trends of epidemic processes of respective infections. The maximum deterioration of the quality of distribution network water due to its contamination with hepatitis A antigen and rotavirus antigen is observed during spring freshet and precedes a seasonal rise in the incidence of hepatitis A and rotavirus infection in the population.
