丙型肝炎病毒(HCV)感染可以导致急慢性肝炎、肝硬化和肝细胞肝癌(HCC),全球大约有1．7亿感染者。急性HCV感染多为亚临床感染,因此急性感染的早期诊断比较困难。HCV感染的慢性化率较高,约70％的成年感染者会发展为慢性感染。HCV持续感染20年后发生肝硬化的概率约为10％-15％,感染30年后HCV Hepatitis C virus (HCV) infection can cause acute and chronic hepatitis, cirrhosis and hepatocellular carcinoma (HCC), with approximately 170 million infections worldwide. Acute HCV infection is mostly subclinical infection, so early diagnosis of acute infection is more difficult. HCV infection has a high rate of chronicity and about 70% of adult infections develop chronic infection. The probability of developing cirrhosis after 20 years of persistent HCV infection is about 10% -15%. After 30 years of HCV infection
