To clarify the mode of hepatitis B virus infection, the closed wards in a mental hospital were selected and the serum collected periodically from patients were examined for liver function and HBV infection for three years. HBsAg and HBsAb were tested by immune adherence hemagglutination test and passive hemagglutination test respectively. Positive rates of HBV (HBsAg plus HBsAb) were 44.2%, 34.0%, 43.7% and 43.3% in January of each year and in December of the third year respectively. Among a total of 235 patients 26 cases of hepatitis were found, but HBsAg was detected in only one case. At the time of admission, HBsAg and HBsAb were detected in 5.8% and 42.3% respectively, although 43.0% of patients who were negative for HBV became positive after admission. Eight persistent carriers of HBsAg were also detected, but the rates of HBV infection related to these carriers were not high. From these results, it can be said that high risk of HBV infection was not observed in this hospital.
