摘　　要：分析了经临床和血清学确诊的散发性戊型肝炎１２７例的流行病学和临床特征。结果表明，患者以中年为主，平均４４．４±１３．５岁，男多于女，为５．７∶１。该病全年散发，３～５月份较多见、占４４．１％。患者以从事管理、经贸和经常外出人员为主。７９．５％的患者有经常在外就餐史，无家庭聚集和续发病例，推测传播途径可能与不洁饮食有关，但明确的感染来源不清。患者临床症状明显，预后较好，与同期住院的甲型肝炎比较存在着某些差别。Epidemiologic and clinical features of 127 hospitalized patients with sporadic hepatitis E from Jan. 1993 to Dec. 1994 was analyzed. The results showed that sporadic hepatitis E mainly affected middleaged adults(44. 4± 13. 5 years old ), while children were rarely affected. There was a significant difference between sex distribution . with a male to female ratio of 5. 7 : 1. There were sporadic cases in each month ,but the highest proportion occured during March to May ,accounting for 44. 1% of all. 79. 5% of all cases had a history of frequent eating out of home. There were no secondary cases among exposed household members. It was suggested that the major mode of transmission might possibly be by contaminated food. Most cases showed obvious symptoms and the prognosis was favourable. Comparing with 125 hospitalized patients with sporadic hepatitis A during the same time, there were some differences in epidemiologic and clinical features.
