title: Hepatitis delta virus infection in different time periods in Japan.
abstract: To investigate the prevalence of hepatitis delta virus (HDV) infection in different time periods between 1973 and 1988, antibody to hepatitis delta antigen (anti-HD) was tested for in sera collected from 1088 cases with acute or chronic hepatitis B virus (HBV) infection treated at Kure National Hospital. Between 1979 and 1983, anti-HD was first detected in 16% (four of 25 cases) of patients with acute hepatitis B, in 6.8% (11 of 161 cases) of asymptomatic HBV carriers and 26% (51 of 196 cases) of those with chronic liver disease. Except for this time period anti-HD was hardly detected. These findings indicate that sporadic HDV infections existed in this area between 1979 and 1983.
