入伍新兵人群甲型病毒性肝炎血清抗体水平监测

目的　了解入伍新兵人群中甲型病毒性肝炎（甲肝）病毒IgG抗体的分布情况。方法　采用回顾性血清流行病学调查方法，利用酶联免疫吸附试验技术，对近4年来自6个省市的325名入伍新兵血清进行了甲肝病毒IgG抗体检测,统计分析其阳性率。结果　发现各年间入伍新兵血清甲肝病毒IgG抗体差别不显著，为31.87%～41.76%,平均37.85%;地区间差别较大,湖北省（49.21%）和河南省（40.00%）较高,山西省最低（26.67%）;新兵入伍前学历和工作与否与其甲肝病毒IgG抗体阳性率差异无统计学意义。结论　入伍新兵人群中甲肝病毒IgG抗体阳性率有地区差异,阳性率明显低于70%警戒线,应引起高度重视。
