为了解1998年水灾后病毒性肝炎的主要流行型别，于1999年2～4月，在6个受灾省（自治区，下同）收集了就诊肝炎病人血清1135份．用酶联免疫吸附试验检测甲、乙、戊型肝炎感染指标．结果表明：（1）在水灾后的病毒性肝炎病例中，约半数为急性肝炎（45．73％），半数可能为慢性乙型肝炎（54.27％），后者少数为其它型肝炎；（2）在急性肝炎中，甲、乙、戊型肝炎分别占57.42％、30.06％和12．52％；（3）在HBsAg阳性者中，能定为急性肝炎的只占32.21％．在这里21％的急性肝炎中甲、乙、戊型肝炎的比例分别为26.18％、68.06％和5.76％，表明水灾区的急性病毒性肝炎以甲型肝炎为主，慢性肝炎以乙型肝炎为主．上述两种类型是水灾后预防的重点。
To understand the major epidemic patterns of viral hepatitis after the 1998 floods, from January to April 1999, 1135 serum samples of hepatitis patients were collected from 6 affected provinces (autonomous regions and the same below). Enzyme linked immunosorbent assay for hepatitis A, B, hepatitis E infection indicators. The results showed that: (1) About half of the cases of post-flood viral hepatitis were acute hepatitis (45.73%), half of them were chronic hepatitis B (54.27%), and the latter were other hepatitis ) Among acute hepatitis, A, B and E accounted for 57.42%, 30.06% and 12.52% respectively; (3) Among the HBsAg positive persons, only 32.21% were acute hepatitis. The proportion of A, B and E hepatitis in 21% of acute hepatitis is 26.18%, 68.06% and 5.76% respectively, indicating that the acute viral hepatitis in flood-affected areas is mainly hepatitis A and the chronic hepatitis is hepatitis B the Lord. The above two types are the focus of post-flood prevention.
