摘要
了解中学生乙型肝炎病毒(HBV)的感染状况,评价乙型肝炎疫苗在预防免疫中的效果。方法:采用微量手指末梢血稀释液酶联免疫法(ELISA)测定HBsAg、抗-HBs。结果6451份微量末稍血检出:HBsAg(+),标本155份,阳性检出率为2.40%;抗-HBs(+)标本3999份,阳性检出率61.99%。结论入学新生的HBV血清标志物阳性率明显低于正常人群中约10%的水平,说明乙肝疫苗的接种和国家、学校重视的原因,目前中学生HBV感染率已有所下降,乙肝计划免疫预防工作取得一定效果。
Objective： to understand the infectious status of Hepatitis B virus （HBV） in the middle school students and assess the effects of the preventive immunity of HBV vaccine. Methods：a drop of blood from the rip of finger was taken and HbsAg, anti-HBs wee determined by ELISA. Results：out of 6451 blood samples, 155 samples were detected HbsAg positive, accounting for 2.40%. 3999sampls were detected positive, accounting for 61.99%. Conclusions：the positive rate of HBV serological markers among the middle school students was lower considerably than among normal population. Due to the inoculation of HBV vaccine and government and school＇s attention, the infection rate of HBV has been decreased and preventive immutity of HBV has already a good effect.
