总结丙型肝炎１０４例，其中乙、丙型肝炎病毒双重感染６３例，认为二者重叠感染是我国丙型肝炎病毒（ＨＣＶ）感染的主要模式．血源性传播为丙肝的主要传播途径。肝细胞的损害程度受两种病毒复制活跃程度的影响，抗ＨＢｃ—ＩｇＭ阳性组，乙型肝炎病毒（ＨＢＶ）复制活跃，肝细胞损害重，预后差；并发ＨＣＶ感染后可加重肝细胞损害，慢转率增高。ＨＣＶ感染后对ＨＢＶ复制有一定抑制作用。
Summary of 104 cases of hepatitis C, of which 63 cases of hepatitis B and C virus double infection, that the two overlap infection is the main mode of hepatitis C virus (HCV) infection in China. Blood-borne transmission of hepatitis C is the main route of transmission. The extent of the damage of hepatocytes was affected by the degree of replication activity of the two viruses. Anti-HBc-IgM positive group, active replication of hepatitis B virus (HBV), severe hepatocellular damage, poor prognosis; complicated with HCV infection may aggravate hepatocellular damage, Slow rate increased. HBV infection after infection has a certain inhibitory effect.
