Since the etiologic diagnoses of hepatitis A, B, C, D and E were established, there are still a part of patients with hepatitis in which the pathogenic causes can not be identified. After a lot of epidemiological and laboratory investigations, it was speculated that other parenterally transmissible pathogens causing human hepatitis existed.

自从建立起甲、乙、丙、丁、戊5种肝炎病毒的病原学诊断之后，仍有少部分肝炎患者的病因得不到明确，因此不少学者试图探索是否还有新型肝炎病毒的存在，并进行了大量的流行病学和实验诊断的研究，认为的确存在可经肠道外传播并引起人类肝炎的致病因子。1995年Simons等成功地克隆出2株黄病毒RNA序列，称之为GBV-A、GBV-B。

The interaction of pathogens and host play a key role in pathogenicity.
