采用逆转套式聚合酶链反应，从３７９份不同人群血清中发现庚型肝炎病毒（ＨＧＶ）ＲＮＡ阳性者４１例。对该４１例的临床症状、体征及肝功能转氨酶（ＡＬＴ）、总胆红素（ＴＳＢ）水平进行分析，结果提示，ＨＧＶ感染存在无症状携带状态，其相关性肝炎易慢性化，但肝功能损害轻微，重叠ＨＢＶ或ＨＣＶ感染不加重肝炎的临床。
Reverse transcriptase polymerase chain reaction was used to detect 41 positive cases of hepatitis G virus (GGV) RNA from sera of 379 different human subjects. The clinical symptoms and signs of 41 cases and the levels of liver function aminotransferase (ALT) and total bilirubin (TSB) were analyzed. The results suggest that HGV infection has the status of asymptomatic carriage and the related hepatitis is easy to be chronic, but the liver function Mild, overlapping HBV or HCV infection does not aggravate hepatitis clinical.
