| 摘 要： | 目的了解1996-2008年云南省西畴县甲型病毒性肝炎(甲肝)流行情况,采取有针对性的预防措施,为甲肝防治工作提供参考依据。方法对1996-2008年西畴县疾病预防控制中心的甲肝病例报告数据进行流行病学分析。结果 1996-2008年西畴县共报告甲肝779例。1999年发病率最高,为101.03/10万,2006年发病率最低,为4.39/10万,年均发病率为31.42/10万。1996年、1999年西畴县甲肝发病出现以县城为中心的点状暴发,从2000年起呈总体下降趋势,但有小幅波动。13年间地区发病最高为1999年的西洒镇,发病率达485.98/10万,发病数居前3位的职业是学生、农民、幼托及散居儿童,发病年龄主要集中在10~25岁,占总病例数的60.00%。男女甲肝发病比为1.42∶1。结论自2000年以后,西畴县加大了甲肝疫苗的接种力度,县城进行饮用水改造及消毒,甲肝发病呈总体下降趋势,发病率由2000年的31.92/10万下降到2005年的6.41/10万。应加强对重点人群、重点年龄组和易感人群的保护,进一步提高甲肝疫苗接种率。
