The prevalence of hepatitis C virus (HCV) infection varies in different populations, ranging from as low as 0.6% in volunteer blood donors to as high as 80% in injection drug users. The prevalence of HCV in a population can be predicted by risk factors associated with the transmission of infection. These risk factors include injection drug use, blood product transfusion, organ transplantation, hemodialysis, occupational injury, sexual transmission, and vertical transmission. We review the literature regarding the incidence and prevalence of HCV infection and the evidence supporting various modes of HCV transmission.
丙型肝炎病毒（HCV）感染在不同人群中的流行率有所不同，从志愿献血者中低至0.6%到注射吸毒者中高达80%不等。人群中HCV的流行率可通过与感染传播相关的风险因素来预测。这些风险因素包括注射吸毒、输血制品、器官移植、血液透析、职业伤害、性传播和垂直传播。我们回顾了有关HCV感染发病率和流行率的文献以及支持HCV各种传播方式的证据。
