摘要: 目的了解吸毒人群中病毒性丙型肝炎（丙肝）病毒（HCV）感染状况及影响因素。 方法对北京市石景山区2007-2008年新入所戒毒人员进行问卷调查，并采集5 ml静脉血检测抗-HCV。结果345名戒毒人员中，检出抗-HCV阳性者179例，抗-HCV阳性率为51.9%（95%CI：46.6%～57.3%），其中注射吸毒者抗-HCV阳性率为73.5%（169/230），共用注射器吸毒者抗-HCV阳性率为90.5%（76/84）。结论北京市石景山区吸毒人群HCV感染率较高，静脉吸毒和共用针具是传播HCV的高危因素，存在向一般人群传播的可能。Abstract: ObjectiveTo know the prevalence of Hepatitis C virus (HCV) infection and the risk factors among the drug users and provide scientific evidence for the HCV infection control.
