摘要
作者于1988年1月—12月对某3个野战部队急性病毒性肝炎的发病、漏报和流行病学特征等进行了流行病学研究.结果显示:该部队人群年发病率为1.35‰,其中甲型肝炎(甲肝)年发病率为0.71‰,乙型肝炎(乙肝)为0.34‰,非甲非乙型肝炎为0.07‰,不明型别为0.23‰.根据其中2个单位的随机抽查,漏报现象严重(6/13),实际年发病率估计高于1.35‰.年龄:甲肝为20±1.99岁,乙肝为25±279岁,两者在统计学上相差非常显著(t=5.53, P<0.01).由于该部队抗-HAV阳性率已达82.5％,对传播具有了一定的免疫屏障作用,而乙肝以亚临床感染为主,所以流行形式主要为散发,偶有爆发.
The occurrences , underreporting and epidemiologic features of aculc viral hepatitis in three field - type units were studied from January to December , 1988. The annual incidence was 1.35 ‰ in the army ,in which hepatitis A covered 0.71 ‰, hepatitis B 0.34 ‰, and hepatitis non - A , non - B 0.07 ‰. But many patients (6/13 ) in two of the three units failed to report, so the actual incidence was higher than 1.35 ‰. The epidemic pattern of hepatitis was mainly sporadic ; whereas it sometimes may be a small outbreak .
