目的了解本地乙型肝炎流行状况,探索乙肝流行因素及流行规律。方法随机与整群抽样相结合,对1岁以上共650人进行了乙型肝炎血清流行病学调查。结果HBsAg阳性率为2.15%,低于2002年全国乙型肝炎血清流行病学调查结果,抗-HBs、抗-HBc阳性率分别为54.31%、17.69%,HBsAg、抗-HBs、抗-HBc阴性率皆为41.69%。结论新生儿实施乙肝疫苗预防接种已取得显著成效,HBsAg、抗-HBc阳性率低年龄低于高年龄,抗-HBs阳性率低年龄高于高年龄。但乙肝疫苗免疫成功率偏低。
Objective To understand the epidemic situation of local hepatitis B and to explore the prevalence and prevalence of hepatitis B. Methods Randomized and cluster sampling combined with a total of 650 people over the age of 1 had a hepatitis B serological survey. Results The positive rate of HBsAg was 2.15%, lower than that of the national serological survey of hepatitis B in 2002. The positive rates of anti-HBs and anti-HBc were 54.31% and 17.69%, respectively. HBsAg, anti-HBs and anti-HBc were negative Rates were 41.69%. Conclusions Newborns vaccinated with hepatitis B vaccine have achieved remarkable results. The positive rates of HBsAg and anti-HBc are lower than those of the older ones. The positive rates of anti-HBs are higher than those of the older ones. However, hepatitis B vaccine immunization success rate is low.
