Change on hepatitis B virus after inoculating HepB

ObjectiveTo know infection rate of HBVin serum after HepB was inoculated in Karamay.Methods11801 persons aged between 0 and 80 were sampled by r andomization in three districts of Karamay.HepB inoculation rate and HBV infection rate were investigated and HBsAg,HBsAb,HBcAb,HBeAg and HBeAb were tested.ResultsRate of HepB inoculation was 96.33% in persons aged under 20 and 45.44% in groups aged over 25,the difference was significiant between two groups(P<0.01).By contrast with the year of 1990,positive rate of HBsAg(0.19%~5.41%)and HBV(1.64%~37.84%)declined evidently in groups aged under 20(P<0.01).Positive rate of HBsAg(5.22%~10.43%)didn't changed(P>0.05)and positive rate of HBV(39.92%~53.16%)rised(P<0.01)in groups aged over 25.ConclusionThat HepB inoculation rate should be improved is effective measure to control infection of HBV.Immunization barrier should be builtin whole population through improv ingrate of HepB inoculation among the adults.
