军队散发性急性病毒性肝炎的流行病学研究

1993年3月～1994年2月对驻川某部队进行病毒性肝炎发病情况监测,并对其散发病例。经确诊急性病毒性肝炎患者血清标本72份,用ELISA方法进行分型检测,并作流行病学分布研究。结果:以甲肝为主(占52.78％)、乙肝为次(占20.83％)、丙肝最少(占1.39％),丁、戊肝两型均为2.7％。监测结果表明:该部病毒性肝炎年发病率为191.88/10万;干部肝炎发病率略低于战士,然乙肝发病率则较战士为高(P<0.05);新兵明显高于老兵,且甲肝发病率亦远较老兵为高(P<0.01)。提示:在肝炎防治中,应突出以甲、乙两型为重点,应以干部和新兵为主的预防对象。

EPIDEMIC INVESTIGATION OF SPORADIC ACUTE VIRUS HEPATITIS IN AN ARMY UNIT

Epidemic conditions of virus hepatitis had been investigated in an army unit from March. 1993 to Feb, 1994. 72 cases of acute virus hepatitis were found and their sera were tested with ELISA so as to determine their serum classification of virus hepatitis. The results showed that most cases were hepatitis A(52. 78%), hepatitis B was less(20. 83%) than hepatitis A, both hepatitis D and E were greatly less (2. 7%) than hepatitis B and hepatitis C was the leastd. 39%) among five types. The incidence of virus hepatitis was 191. 88/100,000 a year in this unit. Army officers suffered less from this illness than soldiers, but their incidence of hepatitis B was higher than that of soldiers (P<0. 05). More recruits had the illness than veterans (P<0. 01). It was indicated that both hepatitis A and B were the major preventive targets in the army, especially to the officers and recruits.
