abstract: Authors examined HBsAg, anti-HBs and anti-HBc of 471 people in Xiyang, Shanxi. The positive rate is 10.19%, 34.61% and 19.11% respectively. The total infection rate of HBV is 52.65%. It indicates that Xiyang county is highly infectious area of HB. The age distribution of positive rate of HBsAg, anti-HBs, and the infection rate of HBV present special model: i.e. goes up along with age's growing, up to 30 years old, it gets the high peak. After 30 years old, the positive rate of HBsAg is going down along with the age's growing, the positive rate of anti-HBs and the infection rate of HBV go down a little. The group of 50 years old has a high peak again. The positive rate of HBsAg of peasant is remarkable higher than cadre's. The infection rate of HBV of peasant is the highest, it is 59.55%. The infection rate of HBV of the people who work in food units is lowest, because they are examined regularly. The infection of man and woman is same.
