为了摸清部队病毒性肝炎与甲型肝炎实际发病率及流行病学特征，对部队肝炎防治提供科学依据。方法：以整群抽样方式抽取观察对象，收集相关资料和血清标本，用ＥＬＩＳＡ 检测肝炎病毒感染指标血清学分型。结果：调查结果表明１９９３ ～１９９８ 年部队肝炎发病率为０．９０ ‰，各年发病率为０ ．６５ ‰～１ ．０１ ‰，其中甲型肝炎发病率为０ ．１７ ‰，呈逐年下降趋势，发病率由１９９３ 年的０ ．６３‰下降至１９９８ 年的０．０５ ‰，以及所占比重由１９９３ 年的３６．３６ ％ 下降至１９９８ 年的７ ．９６ ％ 。在肝炎患者中，干部肝炎发病率（１ ．６３‰） 明显高于战士（０．９０‰） ，而战士甲型肝炎发病率（０．２２‰） 高于干部（０．１８ ‰） 。并以散发形式为主，甲型肝炎２ ～４ 月发病数占５０ ％ 。结论：该部队每年肝炎的实际发病率远高于报告发病率，针对部队肝炎易感者进行肝炎疫苗接种，能有效控制肝炎对部队的危害
In order to find out the actual incidence of viral hepatitis and hepatitis A and epidemiological characteristics of troops, to provide a scientific basis for the prevention and treatment of hepatitis units. Methods: The subjects were collected by cluster sampling, and the related data and serum samples were collected. Serological typing of hepatitis virus infection was detected by ELISA. Results: The survey results showed that the incidence of hepatitis in the armed forces from 1993 to 1998 was 0.90 ‰, with an incidence of 0 in each year. 65 ‰ ~ 1. 01 ‰, of which the incidence of hepatitis A is zero. 17 ‰, showing a declining trend year by year, the incidence rate from 0 in 1993. 63 ‰ to 0.05 ‰ in 1998, and its share dropped from 36.36% in 1993 to 7 in 1998. 96%. Among hepatitis patients, the incidence of cadre hepatitis (1.63 ‰) was significantly higher than that of soldiers (0.90 ‰), while the rate of hepatitis A (0.22 ‰) in soldiers was higher than that of cadres (0.18 ‰). And mainly in the form of distribution, hepatitis A incidence of 2 to 4 months accounted for 50%. Conclusion: The actual incidence of hepatitis in the army is much higher than the reported incidence in each year. Hepatitis vaccination against susceptible hepatitis in troops can effectively control the harm of hepatitis to the army
