目的描述中国丙型肝炎流行特征及其变化趋势.方法收集1997-2011年中国丙型肝炎报告病例资料,资料整理和数据分析采用SPSS 19.0软件.结果自1997年中国丙型肝炎报告病例数及发病率逐年增加,特别是在2004年网络直报以来,每年报告病例数快速上升,报告发病率从2004年的3.03/10万上升至2011年的12.97/10万.15～49岁年龄组每年报告例数所占比例均>50%,≥50岁年龄组报告例数和所占比例同样逐年上升,随年龄增加发病率呈上升趋势.2005-2011年全国报告城乡病例数均逐年增加,病例数比从2005年的1.47下降至2011年的0.99.1997-2011年全国31省(自治区、直辖市)报告发病率均呈增长趋势,发病率较高的地区多分布在北方省份.74.8%的HCV/HIV双重感染者报告有注射毒品史或献血浆史或输血史或手术史.结论中国丙型肝炎病例报告发病数及发病率均逐年上升,应加强重点人群和地区疫情监测.
