福建省2005-2011年丙型肝炎疫情快速上升原因分析

Cause analysis for rapid increasing of hepatitis C epidemic in Fujian(2005-2011)

目的分析福建省2005-2011年丙型肝炎(丙肝)疫情快速上升原因,为防控提供依据。方法对丙肝疫情资料进行描述性流行病学分析。结果福建省丙肝发病率从2005年的1.20/10万,到2011年的7.01/10万,呈逐年快速上升态势;死亡率无显著升降。实验室诊断数的占比从2005年的59.5%,到2011年的93.9%,呈逐年上升趋势。各设区市发病率均呈逐年上升态势,尤以莆田市升幅最大、升速最快,年均发病率最高(15.88/10万),年龄别发病率也最高,其实验室诊断病例占比、病例数的城乡比、性别比均比其他设区市高,且农民病例占比大。结论莆田秀屿区的丙肝高发村庄的筛查结果影响了全省疫情态势。报告疫情低估了实际疫情,应加大其防控力度。
