摘要
目的分析乙型肝炎(乙肝)疫苗(Hepatitis B Vaccine,HepB)广泛使用后,乙肝病毒表面抗原(HBsAg)在不同时期、不同人群的携带情况,为乙肝的预防控制提供依据。方法以全市≤18岁人群为调查对象,采用酶联免疫吸附试验检测人群中HBsAg携带情况。结果2000年检测12847人,HBsAg阳性1097例,阳性率8.54%;2006年检测102699人,HBsAg阳性2399例,阳性率2.34%。随着2000年对全市1~18岁人群HepB查漏普种和世界银行贷款疾病控制项目计划免疫子项目HepB接种的实施,尤其是2002年HepB纳入免疫规划后,各个年龄段人群HepB接种率大幅度提高,经过6年时间≤18岁人群HBsAg阳性率下降72.59%,0~、4~、8~、12~、15~18岁人群HBsAg阳性率分别由2000年的3.76%、4.74%、5.59%、8.51%、12.58%下降到2006年的0.30%、1.39%、2.52%、3.03%、2.98%,各年龄段人群HBsAg阳性率下降非常显著。结论各年龄段人群中HBsAg阳性率的下降与HepB接种有直接关系,HepB对预防控制乙肝病毒感染效果明显,提示除做好新生儿HepB预防接种外,成人HepB接种应逐步加强。
Objective To analyze the positive rate of HBsAg in different population at different periods after widely Using Hepatitis B Vaccine and provide strategy for Hepatitis B Control. Methods Using ELISA method to detect the HBsAg carrier in polulation under 18 years old in local area. Results After six year investigating, the HBsAg carrier rate in tested population decreased. For 0--4,4--8,8--12,12-15,15--18 age group, the carrier rate were 3.76% vs 0.30%, 4. 74% vs 1.39%,5.59% vs 2.52%,8. 51% vs 3.03%,and 12.58% vs 2.98% in 2000 and 2006. Conclusion The reduction in carrier rate had a direct relationship with Hepatitis B Vaccine inoculation. Hepatitis B Vaccine had important effect to Hepatitis B control. We should gradually intensify Hepatitis B Vaccine inoculation. It is not only for newborn but also for adult.
