The lower percentage of viral hepatitis in aged compared with young people was confirmed in a study of 1,335 cases of this disease. However, when referred to the total population in related age groups, the actual incidence appeared not so low as it was previously believed to be. This may be due to rarer contacts rather than to immunity. The increasing incidence of inoculated hepatitis in the higher age groups was confirmed. However, it is doubtful if the increasing incidence of inoculated hepatitis alone could be responsible for the reduced life expectancy in the total population of aged people with viral hepatitis. The rather poor risk in the aged can be explained by the more severe and longer course of the disease in a less efficient liver.
