通过人口调查获得的输血感染丙肝长期(10年以上)存活机率的数据,对于制订政策是需要的,但目前尚无1981年之后的输血感染丙肝存活的病人的资料。过去常用1981年明尼苏达Olmsted 县的受血者的10年存活率的数据,但这些数字很可能不能反映上世纪90年代的输血感染者的存活率。HCV回顾性研究显示输血感染丙肝后5至10年的存活率为26％～41％。这些资料没有设计计算输血后感染丙肝的存活率,从现有资料推算受者存活期有一定困难。纽约大学医学部HCV回顾性研究组研究了输血后存活率,他们报告了1988年至1996年输血感染丙肝病人的存活率为4年。在所研究的695例中,
Data obtained through censuses of long-term survival (over 10 years) of HCV infected blood transfusions of HCV are needed for policy development but there is no data available on the survival of HCV infected blood transfusions after 1981. The 10-year survival rates of blood recipients in Olmsted County, Minnesota, used to be used in the past, but these numbers probably will not reflect the survival rates of blood transfusions in the 1990s. HCV retrospective studies have shown survival rates of 5% to 10% after transfusion of hepatitis C from 26% to 41%. These data are not designed to calculate the survival rate of hepatitis C infection after transfusion, from the available data to predict the survival of the recipient there are some difficulties. The New York University School of Medicine HCV retrospective study studied posttransfusion survival rates and reported a survival rate of 4 years in patients transfused with hepatitis C from 1988 to 1996. Of the 695 studied,
