目的了解沙河治理移民HBsAg携带率与抗-HBs水平,为乙肝防治提供依据。方法对沙河治理2007年鹿邑等4县1～85岁移民3 015人进行血清免疫检测(HBsAg和抗-HBs)。结果 HBsAg阳性率为4.44%,抗-HBs阳性率为28.22%,均低于河南省同期HBsAg阳性率5.17%;抗-HBs阳性率52.66%的平均水平。其中5～15岁年龄组抗-HBs阳性率为34.80%,而HBsAg阳性率为4.07%,远远高于城市该年龄组HBsAg阳性率0.40%。结论人群抗体水平低,是HBsAg感染率高的重要原因,提示提高乙肝疫苗接种率,强化接种,提保持人群高抗体水平的重要性。
Objective To understand the HBsAg carrier rate and anti-HBs levels of immigrants in Shahe, and provide evidence for the prevention and treatment of hepatitis B. Methods Sand immunization (HBsAg and anti-HBs) was performed on 3 015 people from 1 to 85 years of immigrants from 4 counties in Luyi County in 2007. Results The positive rate of HBsAg was 4.44% and the positive rate of anti-HBs was 28.22%, both of which were lower than those of HBsAg positive rate of 5.17% and anti-HBs positive rate of 52.66% in Henan province. Among them, the positive rate of anti-HBs in the age group of 5-15 years was 34.80%, while the positive rate of HBsAg was 4.07%, which was much higher than the 0.40% positive rate of HBsAg in this age group. Conclusion The low antibody level in human population is an important reason for the high infection rate of HBsAg, suggesting the importance of improving hepatitis B vaccination rate, enhancing vaccination and raising high antibody levels in the population.
