摘要
目的探讨银川市流感流行趋势,对流感防制策略的制定提供建议。方法应用常规血凝抑制实验微量半加敏法对银川市不同年龄组人群进行流感抗体水平血清学测定。结果共采集样本1513份,其中H1N1阳性率为64.03%,H3N2阳性率为32.41%,BV阳性率为39.93%,BY阳性率为31.42%。结论H1N1是近年来流行的优势毒株,发生大爆发的可能性较小。
Objective To explore the epidemic trend of influenza and to develop strategy to prevent the spread of influenza virus in Yinchuan. Methods The titers of antibodies to influenza virus were detected hemagglutination - inhibition test. Results HI titer≥ 1 ： 20 is considered as positive . The total positive rate of HI titer of antibody to influenza virus： H1N1 （64.03 % ）, H3N2 （33.41% ）, BV （39.93 % ） and BY （31.42%）.
