目的：为了弄清肝病患者中庚型肝炎病毒（ＨＧＶ）的临床感染情况和评估庚型肝炎病毒的致病力。方法：本文调查了２１３例肝病患者的ＨＧＶ感染情况和分析了ＨＧＶ感染的致病力。结果：在２１３例肝病患者中，ＨＧＶ的感染率为７５％（１６／２１３）；其中，ＨＧＶ与ＨＢＶ、ＨＣＶ以及ＨＢＶ和ＨＣＶ的合并感染分别是为７１％（９／１２７）、１８２％（２／１１）和２７８％（５／１８）。未发现ＨＢＶ合并ＨＧＶ感染和单独ＨＢＶ感染两组之间肝功能的损害程度存在差异。结论：以上结果提示，ＨＧＶ通常与胃肠外传播的ＨＢＶ和ＨＣＶ合并感染。而且，ＨＧＶ的致病力看来是温和的 Objective: To understand the clinical status of hepatitis G virus (HGV) in patients with liver disease and to assess the virulence of hepatitis G virus. Methods: This paper investigated HGV infection in 213 patients with liver disease and analyzed the virulence of HGV infection. Results: The infection rate of HGV was 75% (16/213) in 213 cases of liver disease. The co-infection rates of HGV with HBV, HCV, HBV and HCV were 71% (9/127) , 182% (2/11) and 278% (5/18) respectively. There was no difference in the degree of damage to liver function between the two groups of HBV-infected HGV and HBV-infected individuals. Conclusions: The above results suggest that HGV is usually associated with parenterally transmitted HBV and HCV infection. Moreover, the virulence of HGV appears to be mild
