广州市正常人群甲型病毒性肝炎抗体水平调查

作者1988年12月至1989年6月在广州市进行了甲型病毒性肝炎抗体水平调查,抗-HAV检测用ELISA方法。调查正常人群1 663例,抗-HAV阳性率65.1%。各区、县的抗-HAV阳性率差异很大,最高为90.2%,最低为46.7%。抗-HAV阳性率,农村地区(79.3%)显著高于城区(53.9%),散居幼儿(46.5%)显著高于托幼幼儿(20.8%);4岁以下幼儿中男孩(39.0%)显著高于女孩(13.3%)。0~10岁抗体阳性率在15.4%至44.4%之间起伏,其中0~4岁组为29.7%,10~49岁随年龄增长而上升,高峰值在45~49岁。50岁以上缓慢下降。呈甲肝中发区流行图象模式。

The Investigation of Anti-HAV Antibody Rate in Guangzhou Population

There are great differences between the overall positive rate of anti-HAV antibody and those in different districts and counties. Among them, the highest rate was 90.2%, the lowest was 46.7%.
