INVESTIGATION AND ANALYSIS ON THE PREVALENCE OF HEPATITIS B IN MINQING COUNTY

[Objective] To investigate the infection status and incidence of hepatitis B and its epidemic status in Minqing County,so as to provide scientific basis for preventing and curing the hepatitis B.[Methods] Family-based cluster random sampling method was performed in this study.Enzyme linked immunosorbent assay(ELISA) was performed to determine serum marker of hepatitis B.Epidate 3.01 and SPSS13.0 were used to establish database and analyze the data.[Results] A total of 1 409 members were examined.The rate of HBV infection was 65.79%,The masculine rate of HBsAg,HBsAb,HBeAg,HBeAb and HBcAb were 9.65%,43.36%,2.34%,13.91% and 59.61%,respectively.There were 17 HBV infection models.Five indexes that were all negative model showed to be the highest incidence of all the models.The positive rate of HBsAg in male was higher than female.The peak age of HBV was concentrated in the 20 to 24 years old with the HBV incidence of 20.0%,while the incidence of HBV among people below 15 years old 2.93%(8 /273).The positive rates of HBsAg,HBeAb and HBcAb among the people with immunization were lower than those among the people without immunization,while the HB-sAb positive rate among people with medical treatments was higher than those the people without.[Conclusion] We should expand the coverage of HBV immunization and newborn immunization,also we should strengthen of management of blood,blood products and sterilization,so that we can effectively control the incidence of HBV.
