Study on the virus hepatitis through seroepidemiology in Zhaoqing City

Abstract

Objective To know about the epidemic situation of virus hepatitis and Popular law in Zhaoqing City.Provide theoretic Basis for the prevention of virus hepatitis.Methods Three stratifications including seven counties.15 villages and 1698 residents were drew out by the method of multistage stratified and randomized sampling.Anti-HAV IgG,anti-HCV IgG,and anti-HEV IgG in blood samples were detected using ELISA method .HBsAg,anti-HBs and anti-HBc in blood samples were detected by SPHIA method.Results The standardized prevalence rate of hepatitis A,hepatitis B,hepatitis C,and hepatitis E were15.48%,72.82%,25.26%,11.92%.The standardized prevalence rates of hepatitis A,B,and C in city were lower than the rates in village.But the standardized prevalence rate of hepatitis E in urban is higher than in villagers.The prevalence rate of hepatitis A and B increased with the age.The prevalence rate of hepatitis A was higher in female(15.36%) than in male (8.44%).The prevalence rate of hepatitis A was higher in female (41.31%) than in male (34.11%).The prevalence rate of hepatitis A was higher in female(35.90%)than in male(24.50%).The prevalence rate of hepatitis A was higher in female(11.70%)than in male(9.77%).The differences in prevalence rate of hepatitis E between female and male were not signifieant.Conclusions The result revealed some epidemic characters of virus hepatitis in Zhaoqing City.Suggested that since the hepatitis A vaccine was brought into expanded program on immunization (EPI) for near eight years,HAV infection rate had been decreased evidently in children(1～9).since the hepatitis B vaccine was brought into expanded program on immunization(EPI)for near fifteen years,HBV infection rate had been decreased evidently in children(less than 15 years).
