对北京铁路地区部分人群５８例散发性急性非甲非乙非丙型肝炎进行了ＨＥＶ和ＨＧＶ血清学调查。结果如下，抗－ＨＥＶ阳性２２例（３７．９３％），抗－ＨＧＶ和ＨＧＶＲＮＡ阳性共１２例（２０．６８％），其中３例为戊型和庚型肝炎病毒混合感染。戊肝、庚肝病毒感染均以３１～４０岁发病最多，且男多于女；戊肝主要发生在冬春季，多有肠道暴露史；庚型肝炎病毒感染无明显季节性，有肠道外暴露史。ＨＧＶ可单独感染，提示它可能有一定的致病性。
Serological investigation of 58 cases of sporadic acute non-A, non-C, non-C hepatitis in HEI and HGV serogroups was conducted in some areas of Beijing railway. The results were as follows: anti-HEV positive in 22 cases (37.93%), anti-HGV and HGVRNA positive in 12 cases (20.68%), of which 3 cases were mixed type E and hepatitis G virus. Hepatitis E and G hepacitides all have the most incidence at 31-40 years old, and more men than women. Hepatitis E virus mainly occurs in winter and spring, with more history of intestinal tract infection. There is no obvious seasonal infection of hepatic G virus, Exposure history. HGV can be infected alone, suggesting that it may have some pathogenicity.
