title: [Reasons for the decrease in viral hepatitis morbidity in Orekhovo-Zueve].
abstract: Factors of action on the epidemic process in viral hepatitis in Orekhovo-Zuevo leading to a sharp reduction of the incidence of this disease (which before failed to differ from the mean level in the USSR) -- from 154.0 per 100 thousand residents in 1970 to 36.5 per 100 thousand residents in 1975 are considered from the point of view of discussion of the work of Gromashevsky and Birinboim (ZMEI No. 11, 1976). The decisive significance of measures directed to reduction of the incidence of intestinal infections and gamma-globulin vaccinations is refuted. There was revealed a direct 100% correlation between the incidence of positive benzidine tests for blood contamination of medical instruments and the changes in the viral hepatitis morbidity. Planned measures directed to the elimination of factors of parenteral transmission of the infection carried out intensively from 1970 led to reduction of the incidence of viral hepatitis.
