目的了解中学生HBsAg携带率和HBsAb状况,为乙肝防治工作提供科学依据。方法采用ELISA法检测雅安市2008年某中学新生的HBsAb和HBsAg,并对HBsAg阳性者重新采样,检测乙肝“两对半”和肝功。结果共检测1 265名中学新生,HBsAg阳性18人,阳性率1.42%;HBsAg阳性者中“大三阳”占44.44%,“小三阳”占16.67%,肝功检测正常。HBsAb阳性627人,阳性率为49.59%。结论该中学新生HBsAg携带率处于较低水平,没有发现肝功异常者。
Objective To understand the HBsAg carrier rate and HBsAb status of middle school students and provide a scientific basis for the prevention and control of hepatitis B. Methods HBsAb and HBsAg were detected by ELISA in freshmen in a middle school in Ya’an City in 2008. Resamptive HBsAg positive patients were tested for HBsAg and liver function. Results A total of 1 265 middle school freshmen were detected, and 18 were positive for HBsAg. The positive rate was 1.42%. The positive rate of HBsAg positive was 44.44% in the “Big Sanyang” and 16.67% in the “Small Sanyang”. The liver function was normal. 627 HBsAb positive, the positive rate was 49.59%.
