我们于１９９２－１９９４年对甘肃省部分地区、城乡人群乙型病毒性肝炎感染状况，进行了血行流行病学调查。结果显示，ＨＢＶ感染率为５２．３０％，ＨＢｓＡｇ用性率为７．５０％，抗－ＨＢＣ阳性率为４４．８０％，抗－ＨＢｓ阳性率为３６．６５％。ＨＢＶ感染各地分布不均，城乡差异显著，并随年龄增长呈增高趋势。双亲携带ＨＢｓＡｇ状况与子女ＨＢｓＡｇ用性率密切相关。ＨＢｓＡｇ阳性者分布呈明显家庭集聚性，１８６例ＨＢｓＡｇ阳性者中ＨＢｅＡｇ阳性６９人。ＨＢｓＡｇ和抗－ＨＢｓ，同时用性有１２例。
In 1992-1994, we conducted an epidemiological investigation of hepatitis B among hepatitis B virus infection in some areas of Gansu Province and in urban and rural areas. The results showed that the infection rate of HBV was 52.30%, the rate of using HBsAg was 7.50%, the rate of anti-HBC was 44.80% and the rate of anti-HBs was 36.65%. HBV infection is unevenly distributed all over the country, with significant differences between urban and rural areas and with an increasing trend with age. Parents carrying HBsAg status and the rate of children with HBsAg is closely related. The distribution of HBsAg positive was obviously family agglomeration, HBeAg positive in 186 cases of HBsAg positive in 69 people. HBsAg and anti-HBs, while sexual use in 12 cases.
