[The incidence of antibodies to hepatitis A virus in people from Vienna and certain Austrian provinces (author's transl)]

Abstract

The prevalence of antibodies to hepatitis A virus was measured by solid-phase radioimmunoassay in sera of 651 persons from Vienna, Lower Austria, Upper Austria, Carinthia and Burgenland. On subdivision of the subjects according to age groups, a curve resulted which showed a steep rise in persons between 20 and 40 years. In the age groups over 40 more than 80% of the test-persons possessed the specific antibody. In all age groups the population of Vienna showed a higher incidence of hepatitis A antibody than the people from rural areas.
