广西宾阳县农村地区甲乙型肝炎感染标志物的血清学综合分析

对宾阳县农村整群系统随机抽样３５７人检测抗－ＨＡＶ、ＨＢｓＡｇ、抗－ＨＢｃ、抗－ＨＢｓ，其阳性率分别为８３．７５％，２４．３７％，６７．５０％和４０．９０％。ＨＢＶ总感染率７７．５９％；甲乙型肝炎合并感染率６５．８３％。在明宾阳县农村为甲乙型肝炎高发区；人群中普遍存在甲乙型肝炎双重感染。子女ＨＢｓＡｇ阳性率以父母双亲ＨＢｓＡｇ均阳性最高，父母双亲均阴性的子女ＨＢｓＡｇ阳性率最低，抗－ＨＡＶ主要感染年龄是５岁以上人群，ＨＢｓＡｇ阳性率随年龄增长而下降，抗－ＨＢｃ和抗－ＨＢｓ阳性率均随年龄增长而上升。男女性别的ＨＢｓＡｇ阳性率以男性为高。分析甲乙型肝炎血清学标志物的各种情况，为农村地区的甲乙型肝炎综合防制提供科学依据。

A Serology Analysis on the Infections Markers of Hepatitis A and B in the Rursal Areas of Bingyang County,Guangxi

Three hundred and fifty seven persons in total selected from a random cluster sampling in the rural areas of Bingyang County,Guangxi province,were serologically tested their anti-HAV,HBc and anti-HBs.The positive preparation are respectively 83.75,24,37,67.50 and 40.90%.The general unfected rate of HBV was 77.59% and the jointly infected rate if hepatitis A and B was 65.83%.It is astonishing that this population suffered from such a high prevalence and the double infection was so popuar. The children's infected rate of HBsAg according to the rate of their parents,up to the highest rate if both parents were infected,and down to the lowest if both survived the infected. As for the ase infection mode,anti-HAV maijnly infects people over 5,the positive rate of HBsAg declines while age rises,however both anti-Hbcanhd anti-HBs see a rising positive rate with age growing.As to the sex distribution,positive rate of HBsAg of male is higher than that of female.In a word,the serology ahnalysis of hepatitis Aand Binfectious markers has offered a scientific basis for thd rural areas to prevehnt such diseases.
