一九八四年,我们采用反向间接血凝法(RPHA)对同仁地区三所中学(州中学、州民师、县民中)611名不同年龄、性别、民族的学生进行了HBsAg抽样调查分析,结果如下: HBsAg是机体遭受HBV感染的特异性标志611名学生中检出阳性45例,阳性率7.36％。民中、民师及中学阳性率分别为10.06％(15/149)、9.49％(15/158和4.93％(15/304)。被检各校阳性率差别无显著性(X~2=5.25P>0.05),但县民中、州民师两所民族学校阳性率较高,可能与传统的风俗习惯、卫生条件差等因素有关。
In 1984, we conducted HBsAg sampling surveys of 611 students of different ages, sexes and ethnic groups in three middle schools (middle schools, state civilians, and county people) in Tongren district by reverse indirect hemagglutination (RPHA) , The results are as follows: HBsAg is a specific marker of HBV infection in the body of 611 students were positive in 45 cases, the positive rate of 7.36%. The positive rates of Minzhong, Mushu and Middle School were 10.06% (15/149) and 9.49% (15/158 and 4.93%, respectively) P> 0.05). However, the positive rates of the two ethnic schools among county people and prefectures are higher, which may be related to the traditional customs, poor sanitation and other factors.
