【摘要】 目的 :分析 1 996～ 2 0 0 0年 5年间新生共计 2 6 1 4人 ,在入学体检中检出HBsAg阳性率 ,转阴率 ,及时有效加强易感人群接种乙肝疫苗 ,有效控制隐性传播。方法 :选择 1 996～ 2 0 0 0年新生共计 2 6 1 4人。平均年龄 1 7岁。测定采用反向间接血凝试验 (RPHA法 )。抗 -HBs、HBeAg、抗 -HBe和抗 -HBc采用酶联吸附实验 (ELISA)检测。结果 :1 996～ 2 0 0 0年 5年间 ,每年新生HBsAg阳性检出率 1 999年最低为 1 45% ,1 997年最高为 2 6 9% ,累计平均检出率为 2 56 %。男生HBsAg阳性率为 2 56 % ,女生HBsAg率为 1 88% ,西部学生HBsAg阳性率为 2 2 0 % ,东部学生HBsAg阳性率为2 0 4%。结论 :我校在校学生 5年乙型肝炎平均感染率为 2 56 % ,低于全国 8%～ 1 0 %的水平。男女生HBsAg阳性率 ,东西部地区学生HBsAg阳性率均无明显差异。加强对隐性传染源管理 ,可以有效控制乙型肝炎传播。积极有效地加强乙肝疫苗的接种显得非常重要 ,3～ 5年需加强免疫 1次 ,能对易感学生起到很好的保护作用。更多还原

【Abstract】 Objective:In order to immunoenhence Hepatitis B from susceptible crowd to control over recessive epedemic.Methods:RPHA was applied.From1996 to 2000,2614 students in total,aged 17 in avarage,were examined with their Anti-HBs,HBeAg,Anti-HBe,Anti-HBc levels.Results:Form 1996 to 2000,the minirnum of new positive rate of HBsAg was 1.45%(in 1999)and the maximum was 2.69%(im 1997),the average rate was 2.56%.The positive rate of HBsAg of male students was 2.56%,female was 1.88%.That of students from west areas was 2.20%,east areas 2.04%.Conclusion:The average positive rate of HBsAg was 2.56% in the school with in a period of 5 years above mentioned,which was lower than the national rate of 8% to 10%.The difference was not obvious between male and female,students from west areas and east areas.Thus effective immunoenhencement of Hepatitis B is very important.The vaccination should be taken every three to five years.It can protect students susceptible crowd from affaction.更多还原
