来自美国国家卫生研究所召开的一项专家会议的资料表明,几乎有四百万美国人患有“丙型肝炎”(丙肝),患病率为2%,丙肝病毒的携带率还要高几倍。丙肝呈全球性分布,无明确地理界限;普通人群丙肝病毒(HCV)携带率普遍较高,日本为1%~3%,非洲一些国家高达6%。 资料显示,丙型肝炎(丙肝)对人类的威胁及危害并不亚于“乙肝”。丙肝极易慢性化(40%~50%),日本报告高达87.5%;极易发展成肝硬化,西方人70%肝炎后肝硬化由丙肝病毒感染引起。有人对丙肝随访5年,肝脏病理检查证实60%发展成肝硬化。在肝硬化的基础上又可转变为肝细胞癌,由丙型肝炎到肝细胞癌一般需要20年以上。
Information from an expert meeting convened by the National Institutes of Health shows that almost four million Americans have “hepatitis C” (hepatitis C), with a prevalence of 2% and a higher prevalence of hepatitis C Times Hepatitis C is globally distributed with no clear geographical boundaries; the prevalence of hepatitis C virus (HCV) in the general population is generally high, ranging from 1% to 3% in Japan and up to 6% in some African countries. Data show that hepatitis C (hepatitis C) threat to humans and no less harm than “hepatitis B.” Very easy to chronic hepatitis C (40% to 50%), Japan reported up to 87.5%; easily developed into cirrhosis, 70% of Western hepatitis cirrhosis caused by hepatitis C virus infection. Some people have been followed up for 5 years for hepatitis C and 60% confirmed for liver pathology to develop cirrhosis. On the basis of cirrhosis can be transformed into hepatocellular carcinoma, from hepatitis C to hepatocellular carcinoma generally takes more than 20 years.
