为了解宝山区甲乙丙三型肝炎的流行情况,科学地指导肝炎防制工作,1996年4月进行了一次血清流行病学调查,结果报告如下:1 材料和方法1.1 调查对象1996年4月在宝山区泗塘、吴淞镇、大场、罗店、罗泾、罗南、刘行、横沙8个乡镇街道,整群抽样调查0～60岁居民1240人.每人采静脉血3ml分离血清.放-20℃冰箱待检.1.2 检测方法 抗—HAV和抗—HCV用ELISA法,试剂分别购自浙江省医科院和上海科华公司,按说明书操作和判定结果.HBsAg、抗—HBs和抗—HBc用SPRIA法,试剂购自北京生物制品研究所,阳性判断标准HBsAg和抗—HBs为S/N≥2.1.抗—HBc为抑制率≥75%.1.3 数据处理 实验数据输入微机.建立FOXBASE数据库,用Epilnfo 5.01软件进行统计分析.标准化率计算以上海市1992年人口为标准人口.2 结果与分析2.1 HAV感染情况 本次调查705人,抗—HAV阳性303人,阳性率42.08%,男性 36.96%(102/276),女性46.85%(201/429).标化阳性率为
In order to understand the prevalence of hepatitis A and B hepatitis B in Baoshan District and to guide the prevention and treatment of hepatitis scientifically, a serological epidemiological investigation was conducted in April 1996 and the results were reported as follows: 1 Materials and Methods 1.1 Investigation Object In April 1996, Baoshan District Sitang, Wusong Town, a large field, Luo shop, Luojing, Luo Nan, Liu Xing, Hengsha 8 township streets, the cluster sampling survey of residents aged 0 to 60 1240.
