目的 :为了较精确地查明部队病毒性肝炎与甲型肝炎实际发病率及流行病学特点 ,为部队甲肝的防制提供科学依据。方法 :用整体抽样的方法 ,在驻东北、华东、西南、华南野战部队中 ,各抽取一个有代表性的部队 ,前瞻性的观察了 160 360人在 1993年内甲肝发病情况 ,统一方法与统一批号试剂 ,在同样条件下用ELISA检测抗 -HAVIgM。结果 :一年内共发生病毒性肝炎 310例 ,年发病率为 199.3/ 10万 ,其中甲肝年发病率 10 0 .4 / 10万 ,占 51.9%。甲肝发病有 3～ 5月与 8～ 9月两个高峰 ,新兵甲肝发病率 ( 130 .6/ 10万 )高于老兵 ( 81.0 / 10万 ,P <0 .0 1)。结论 :甲肝预防的重点是新兵 ,建议对部队新兵中甲肝易感者接种甲肝疫苗
OBJECTIVE: To provide a scientific basis for the prevention and control of the unit hepatitis A in order to find out the actual incidence and epidemiological characteristics of viral hepatitis and hepatitis A in troops more accurately. Methods: With the method of overall sampling, a representative force was extracted from each of the field troops stationed in Northeast China, East China, Southwest China and South China. Prospective observation was made on the incidence of HAV in 160 360 people in 1993, the unified method and the unified batch number Reagent, anti-HAVIgM was detected by ELISA under the same conditions. Results: A total of 310 cases of viral hepatitis occurred in one year with an annual incidence of 199.3 / 100 000, of which 100.41 million were hepatitis A cases (51.9%). Hepatitis A incidence in March to May and August to September two peaks, the incidence of recrudescent hepatitis A (130.6 / 100,000) higher than veterans (81.0 / 100,000, P <0.01). Conclusions: The focus of prevention of hepatitis A is recruit, it is recommended to recruit hepatitis A vaccine
