中文摘要:
      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.
英文摘要:
      Objective To analyze the epidemiological characteristics and changing trend as well as the related affecting factors of hepatitis C in China.Methods Data analysis was performed based on the case-reporting data of hepatitis C from 1997 to 2011,using SPSS 19.0.Results The number of reported cases and incidence of hepatitis C had been increasing annually since 1997,especially in 2004.The hepatitis C reported incidence increased from 3.03 per 100 000 in 2004,to 12.97 per 100 000 in 2011.The 15 to 49 age group accounted for more than 50% of all the reported cases,seen in every year.The number and proportion of hepatitis C reported cases among those over 50 year-olds had an annually increase.From 2005 to 2011,the number of cases in both urban areas and rural areas increased annually,while the urban-rural ratio decreased from 1.47 in 2005 to 0.99 in 2011.There appeared an increasing trend of hepatitis C reported incidence in China,with most of the high reported incidence of hepatitis C fell in the northern parts of China.74.8% of the HCV/HIV co-infected cases had histories of intravenous drug use,plasma donation,blood transfusion or surgical operation.Conclusion The reported number and incidence of HCV infection had been increasing annually.To develop a more realistic control measures for hepatitisv C,it is necessary to strengthen the monitoring program and carrying out specific epidemiological study among target groups and key areas.
