[Epidemiology of hepatitis (author's transl)].

Within the scope of a field survey carried out in the Tyrolean village of Oberperfuss in April 1977, a questionnaire was filled out by 296 men and 315 women aged between 20 and 64 years and the HBs Antigen (HBs Ag) was determined. 16,9% of the men and 15,9% of the woman, indicated that they suffered once from a liver disease of jaundice. The prevalence of HBs Ag positive subjects in men was 10,2/1000 and in woman, 3,2/1000. The incidence of hepatitis in the political districts of Innsbruck City and County in the above mentioned age group, in 1977 was 0,71/1000 in men and 0,53/1000, in women. Out of these, 60% of the male and 66% of the female cases, were HBs Ag positive.
