目的了解云南省普通人群甲型H1N1流感抗体水平,分析和预测其流行趋势,为预防和控制疫情提供依据。方法 2010年1～3月,对云南省不同年龄组部分人群开展了4次调查,用血凝抑制试验进行抗体检测。结果云南省普通人群甲型H1N1流感抗体阳性率为28.3%(452/1 600),3月的抗体阳性率和GMT高于1、2月。结论人群甲型H1N1流感抗体水平较低,仍有大流行的可能。

Objective To understand the level of influenza A (H1N1) antibody in the general population in Yunnan Province, analyze and predict its epidemic trend, and provide the basis for the prevention and control of the epidemic. Methods From January to March 2010, four surveys were conducted among some groups of different age groups in Yunnan Province. Antibody detection was performed with the hemagglutination inhibition test. Results The positive rate of influenza A (H1N1) antibody in the general population was 28.3% (452/1 600) in Yunnan Province. The antibody positive rate and GMT in March were higher than those in January and February. Conclusion The population of Influenza A (H1N1) antibody is low and there is still a possibility of pandemic.
