深圳市2002和2003年人群血清流感抗体检测

目的 了解深圳市部分人群的流感病毒抗体水平，为预防和控制疫情提供依据。方法 2002年10月-2003年10月共两次采集人群血清308份，应用近几年国际、国内及广东省流感病毒代表株，以微量半致敏血凝抑制方法进行抗体检测。结果 人群对各型及亚型毒株的抗体阳性率均有上升，其中对A／New Caledonia／20／99（H1N1）的抗体阳性率由40．6％上升至62．1％；对B／HongKong／2001的抗体阳性率由23．8％上升至76.5％；对B／Victoria／504／2000的抗体阳性率由21.3％上升至79．7％；对A／Panama／2007／99（H3N2）的抗体阳性率分别由77．4％升至80．4％。结论 应加强流感病毒抗原变异株和人群流感病毒抗体水平的监测。
