Investigation on the situation and prevention of HBV infection in psychotic inpatients.

[Objective] To investigate the HBV infection in psychotic inpatients.[Methods] HBV markers of serum were tested by enzyme linked immunoassay(ELISA) in 3755 psychotic inpatients.[Results] Positive rates of HBsAg,HBsAb,HBeAg,HBeAb and HBcAb in serum were 8.81%、 30.81%、 3.12%、 21.54% and 15.29% respectively.The total infection rate of HBV was 43.65%.15 infection models were detected from 1639 HBV positive samples.HBsAg(+),HBsAb(-),HBeAg(-) HBeAb(+),HbcAb(+) accounted for 12.20%,and HBsAg(+),HBsAb(-),HBeAg(+),HBeAb(-),HBcAb(+) accounted for 5.86%.[Conclusion] There are HBV infection sources in psychotic inpatients.Comprehensive measures such as monitor,isolation and disinfection must be taken to prevent the infection of HBV in hospital for psychotic inpatients.
