摘要 调查无锡地区不同成人人群中甲型流感H1、H3、H5、H7、H9血凝抑制抗体水平,分析甲1、甲3流感病毒的流行趋势和人感染H5,H7、H9禽流感病毒的情况。对家禽接触人群272人、一般人群210人用微量半加敏法检测血清中H1、H3、H5、H7、H9血凝抑制抗体,抗体效价≥1:10判为阳性,51:40判为有保护性。无锡地区成人人群中A/京防/262/95(H1N1)血凝抑制抗体阳性率为67.43%、GMT为13.47、保护率为20.95%;A/悉尼/5/97(H3N2)血凝抑制抗体阳性率为76.97%、GMT为19.38、保护率为35,48%,两组人群之间u=2.28,P<0.05。一般人群中H5、H7、H9血凝抑制抗体阳性率分别为0.48%、1.43%、3.18%,家禽接触人群中分别为4.04%、8.82%、20.59%,两组人群之间X2=6.21、P<0.025,X2=12.26、P<0.001和X2=28.97、P<0.001,有高度显著性差异。不同地区家禽接触人群之间H5、H7血凝抑制抗体阳性率没有显著性差异,但H9血凝抑制抗体阳性率在不同地区之间存在高度显著性差异。近几年无锡地区成人人群中H1N1和H3N2流感病毒发生流行的可能性不大;禽H5、H7、H9禽流感病毒在人群中有不同程度的感染,尤以家禽接触人群为甚,应加强对家禽接触人群的监测和干预。
