目的 :了解病毒性肝炎流行病学特征和血清型别 ,为指导部队开展本病防治工作提供科学依据。方法 :收集某部 1995～ 2 0 0 0 .12月疫情和资料及采集住院患者血清 ,采用 EL ISA或 RIA法检则各型肝炎感染的血清学指标 ,进行分析。结果 :某部病毒性肝炎年发病率为 0 .6 5 %～ 1.0 6 %。急性病毒性肝炎患者中 ,甲肝占 4 6 .2 4 %、乙肝 33.33%、丙肝 3.2 2 %、戊肝 1.0 8% ,双重感染占 2 .15 % ,检测指标全部阴性占 13.98% ,病例中急性黄疸型占 5 0 %以上 ,而慢性肝炎以乙型为主 ,占 73.91% (17/ 2 3)。急性肝炎患者以战士为主 ,而慢性肝炎以干部为主。结论 :本部队病毒性肝炎防治工作应以乙型肝炎为重点 。

Objective:To acknowledge epidemiological characteristics and serotypes of viral hepatitis and provide basis for troop's precaution.Methods:Collecting the epidemic situation and related data,and sera of hospital cases from January 1995 to December 2000,using ELISA or RIA detect infected indexes and serotypes of various hepatitis types.Results:The year incident rates of troop's hepatitis changed from 0 65‰ to 1 06‰ in recent years.In hospital cases of acute viral hepatitis,hepatitis A occupied 46 24%;hepatitis B,33 33%;hepatitis C,3 22%;hepatitis E,1 08%;two type hepatitis co or superinfection occupied 2 15%,the cases that all detecting markers of hepatitis were negative occupied 13 98%,acute Jaundice hepatits occupied 50%.In 23 hospital cases of Chronic Viral hepatitis,hepatitis B occupied 73 19%.The acute hepatitis cases were mainly soldiers,and the chronic cases were mainly cadres.Conclusions:In precaution of troop's hepatitis,emphasis should be paid on hepatitis B,and in the same time,precaution measures to hepatitis A should be reinforced as well.
