title: [Role of the instrument transmission factor in the epidemiology of viral hepatitis. II. Methods, materials, chief results].
abstract: The authors conducted a prospective controlled epidemiological observation in two towns of the Moldavian SSR. There were 50 000 persons under observation. Over 300 000 parenteral manipulations carried out in them were recorded. Analysis of the materials obtained on the Minsk-22 computer demonstrated the same incidence of viral hepatitis in the groups given parenteral manipulations and without them. Consequently, the instrumental transmission factor had no essential significance in the epidemiology of viral hepatitis, this corresponding to the results of the authors' preceding theoretical study.
