目的了解乙型肝炎感染状况,评价乙肝疫苗预防效果,为乙型肝炎的防治提供理论依据。方法按整群抽样法,共抽样21～60岁2000人进行乙肝疫苗接种等情况调查和HBV血清感染标志检测。结果这次共调查2000人,其中乙肝疫苗接种620人,接种率为31%。HBsAb阳性者714人(包括接种和未接种者),阳性率35.7%。在接种乙肝疫苗人群中HBsAb阳性率为71.13%。HBsAg阳性率平均为35.7%。结论接种乙肝疫苗能显著降低HBsAg阳性率,提高乙肝疫苗接种率,对预防乙型病毒性肝炎有重要意义。
Objective To understand the status of hepatitis B infection and evaluate the preventive effect of hepatitis B vaccine so as to provide a theoretical basis for the prevention and treatment of hepatitis B. Methods According to cluster sampling method, a total of 2000 people aged 21-60 years were investigated for hepatitis B vaccination and HBV seroprevalence markers. Results A total of 2000 people were surveyed, of which 620 were vaccinated against hepatitis B and the vaccination rate was 31%. 714 people (including vaccinated and non-vaccinated) were HBsAb positive, with a positive rate of 35.7%. The positive rate of HBsAb in vaccinated hepatitis B vaccine population was 71.13%. The average positive rate of HBsAg was 35.7%. Conclusion Hepatitis B vaccination can significantly reduce the positive rate of HBsAg and improve the vaccination rate of hepatitis B, which is of great significance in the prevention of hepatitis B virus.
