目的了解某部病毒性肝炎的流行病学特征,为制订防治策略提供依据。方法采用FoxPro、Excel等软件对某部2000-2009年病毒性肝炎报告数据库进行统计分析。结果 2000-2009年病毒性肝炎发病病例为1 808例,总体发病情况呈现逐年下降趋势,但病毒性肝炎仍高居每年传染病报告发病的首位;在各型病毒性肝炎中,甲型肝炎占5.64%,乙型肝炎占62.61%,丙型肝炎占11.23%,戊型肝炎占2.10%,未分型肝炎占18.42%;发病时间全年均有发生,以5～9月份较多,占总发病数量的49.9%。男性多于女性,战士、干部为发病主体,分别为46.85%、35.23%。甲、乙型肝炎和未分型肝炎主要集中在35岁以下年龄组,丙型肝炎主要发生在55岁以上的中老年人,戊型肝炎35岁以下和55岁以上年龄组相对较多。结论病毒性肝炎仍是危害广大官兵健康最严重的传染病,应予以高度重视,需采取综合措施,以控制病毒性肝炎的发病率。
Objective To understand the epidemiological characteristics of some viral hepatitis and provide evidence for the development of control strategies. Methods The software of FoxPro, Excel and other software was used to analyze the viral hepatitis database of a certain department from 2000 to 2009. Results The incidence of viral hepatitis in 2000-2009 was 1 808. The overall incidence showed a declining trend year by year. However, viral hepatitis still tops the annual report of infectious diseases. In all kinds of viral hepatitis, hepatitis A accounted for 5.64 %, Hepatitis B accounted for 62.61%, Hepatitis C accounted for 11.23%, Hepatitis E accounted for 2.10%, Unfractionated hepatitis accounted for 18.42%; The onset time all occurred in the year from May to September more, accounting for the total incidence 49.9% of the quantity. Men than women, soldiers, cadres for the main disease, respectively, 46.85%, 35.23%. A, Hepatitis B and undifferentiated hepatitis are mainly concentrated in the age group of 35 years of age, hepatitis C occurs mainly in the elderly over 55 years of age, hepatitis E 35 years of age and over the age group of 55 years of age are relatively more. Conclusion Viral hepatitis is still the most infectious infectious disease that endangers the health of officers and men. Therefore, it is necessary to take a comprehensive approach to control the incidence of viral hepatitis.
