摘要 目的了解高海拔地区藏族居民病毒性肝炎的流行程度,为高原地区藏族居民病毒性肝炎防治提供依据。方法采用整群随机抽样方法,随机抽选30户以上,将各户0~59岁农牧民作为调查对象,用ELISA法对HAV、HBV、HCV、HDV、HEV、HGV进行血清学检测,并进行流行病学分析。结果HBsAg携带阳性率较高(16.95%),抗-HCV阳性率1.84%,抗-HEV阳性率0.37%,抗-HDV阳性率0.12%,抗-HGV阳性率1.72%。均低于1992~1995年全国肝炎流行病学的调查。结论农牧区HBV感染率较高,其传播途径除血液、母婴传播外,肠道外或性途径可能为较重要的传播途径。其他4型肝炎感染率较低,可能与当地的流行条件、民族免疫性、遗传性等因素相关。
