目的：了解部队病毒性肝炎的实际发病水平和流行特点．方法：调查驻陕某部队防疫所及该部医院传染科１９９５～１９９７年３ａ期间疫情报卡、传染病报告表及病毒性肝炎患者的病历，并深入连队对各连登记在案的患者逐例核实，同时调查未登记病例．结果：观察部队３５５４３人中，共发现病毒性肝炎９８例，年平均发病率为２７５．７／１０万，其中甲肝２７例，乙肝４１例，非甲非乙型或未分型３０例，该部３ａ平均漏报率为５５．１％；各单位病毒性肝炎发病率差异有显著性（Ｐ＜０．０５）；干部病毒性肝炎发病率达２５３．５／１０万，低于战士（３３２．７／１０万），干部乙肝发病率（１９７．２／１０万）高于战士（１２７．１／１０万），在战士中，老兵乙肝发病率（１０５．８／１０万）比新兵（１７０．５／１０万）低，但差异均无显著性．结论：观察部队病毒性肝炎年发病率与乙肝发病率均高于以往报道的部队病毒性肝炎发病水平，这与陕西为全国的乙肝高发区有关，同时也反映了以往关于病毒性肝炎发病水平的研究资料存在较严重的漏诊及漏报现象
Objective: To understand the actual incidence of viral hepatitis and the prevalence of troops. Methods: To investigate the epidemic cards, infectious disease report forms and viral hepatitis patients’ medical history during a period from 1995 to 1997 in the Department of Infectious Diseases of a certain unit in Shaanxi and the Department of Infectious Diseases of the Ministry of Internal Medicine. Verify and investigate unregistered cases. Results: A total of 35543 people were observed in the army, a total of 98 cases of viral hepatitis were found, the average annual incidence was 275.7 / 100,000, of which 27 cases of hepatitis A, 41 cases of hepatitis B, non-A non-B or non-subtype 30 cases The average rate of false negatives in department 3a was 55.1%. The incidence of viral hepatitis in each unit was significantly different (P <0.05). The incidence of cadmium viral hepatitis was 253.5 / 100,000, lower than that of soldiers .7 / 10 million). The incidence of hepatitis B among cadres was higher than that of soldiers (127.1 / 100,000). Among the soldiers, the incidence of hepatitis B in the veterans was 105.8 / 100,000 more than that of recruits 170.5 / 100000), but the differences were not significant. Conclusion: The annual incidence of viral hepatitis and the incidence of hepatitis B were higher than the previously reported incidence of viral hepatitis in troops, which is related to the high prevalence of hepatitis B in Shaanxi province, and also reflects the past incidence of viral hepatitis There is more serious research data misdiagnosis and omission phenomenon
