目的 了解某部战士人群流感抗体免疫水平和流感的流行趋势 ,为流感的预防和了解流感病毒的变异提供资料。方法 于 1997年 11月、 1998年 4月、 1998年 11月、 1999年 4月 ,连续 4次用微量半加敏血凝抑制法对驻西北某部战士不固定人群进行了血凝抑制抗体的横向检测。结果 甲3 亚型流感抗体水平较高 ,波动也较大 ,1999年春季几乎达极限 ;甲1亚型流感抗体水平不均一 ,有些流行株抗体水平高 ,而有些则很低 ;两种乙型流感流行株抗体水平都很低 ,波动也很小。结论 西北某部军营中 1997～ 1999年同时流行着甲3 亚型流感和甲1亚型流感 ,以甲3 为主 ,乙型流感未见流行
Objective To understand the epidemic trend of influenza antibodies and influenza in some soldiers and to provide information for the prevention and understanding of influenza viruses. Methods In November 1997, April 1998, November 1998 and April 1999, hemichemomegaly and hemagglutination inhibition were used to detect the hemagglutination inhibition antibody Horizontal inspection. Results Influenza A 3 subtype influenza antibody levels were high and fluctuated, reaching almost the limit in the spring of 1999. Influenza A subtype 1 antibody levels were not uniform, and some of the epidemic strains had high antibody levels while others were very low. Influenza pandemic antibody levels are low, the fluctuations are small. Conclusion Influenza A (3) and subtype A (H1N1) influenza viruses prevailed in some military battalions in a certain northwestern part of the country from 1997 to 1999, with A 3 as the mainstay and no influenza B
