丙型肝炎病毒（HCV）主要通过血源性传播，特别易成为慢性感染，特异性表现较少，病情发展较慢。抗HCV抗体或HCV－RNA的检测有助于HCV感染的诊断，如伴有血清转氨酶的异常或肝脏组织病理学的改变即为慢性丙型肝炎。干扰素主要用于有血清转氨酶异常的患者，部分患者延长干扰素治疗时间有助于病情长期缓解，联用ribavirin可能会增强于扰素的疗效，晚期患者可选择肝移植。
Hepatitis C virus (HCV) is predominantly transmitted by blood and is particularly susceptible to chronic infection with less specific manifestations and slower progression. Detection of anti-HCV antibodies or HCV-RNA contributes to the diagnosis of HCV infection, such as abnormal serum aminotransferases or changes in liver histopathology. Interferon is mainly used in patients with abnormal serum aminotransferases, some patients to extend the treatment of interferon is conducive to long-term disease relief, combined with ribavirin may enhance the efficacy of interferon, advanced patients may choose liver transplantation.
