摘　　要：目的了解佛山市南海区人群甲型H1N1流感感染现状。方法按照广东省卫生厅方案采集不同年龄组人群血清标本,用血凝抑制(HI)试验方法进行抗体检测,HI抗体滴度≥1∶40判为阳性。结果南海区甲型H1N1流感阳性率30.42%(146/480),以第三次调查阳性率最高(43.13%),3次调查总体阳性率差异有统计学意义(χ2=20.10,p≤0.001);4～24岁组阳性率最高(46.15%);男女性阳性率差异无统计学意义;城镇人群感染率高于农村,差异有统计学意义(χ2=12.76,p=0.004)。结论南海区发生了甲型H1N1流感社区流行,人群有一定感染率,农村的学校、幼托机构是防控重点。Objective To understand the influenza A（H1N1） infection status in the population of Nanhai District,Foshan City. Methods To collect the serum samples of different age groups according to the schemes specified by Guangdong Provincial Health Bureau,and then conduct antibody identification based on the hemagglutination inhibition（HI） test method;In case the HI antibody titer is ≥1∶40,it can be judged as positive. Results The positive rate of the influenza A（H1N1） infection in Nanhai district is 30.42%（146/480）,with the highest rate at the third research（43.13%）.The difference in the overall positive rate between the three times of research shows statistic significance（χ2=20.10,p≤0.001）.The group of Age 4 to 24 has the highest positive rate（46.15%）.The difference in the positive rate between male and female presents no statistic significance.The urban population has a higher infection rate than the rural population,and the relevant difference bears statistic significance. Conclusion There was an outbreak of influenza A（H1N1） in the communities of Nanhai district,indicating a significant infection rate.The schools and nurseries in villages shall be the focus for the prevention and control of this disease.
