【摘要】 目的了解2006年广州市职业人群禽流感H5和H9亚型的接触感染情况,为防治人禽流感提供科学依据。方法采集广州市12个区从事饲养、销售和屠宰家禽的职业人群的静脉血831份,一般人群血液样品735份,通过血凝抑制实验进行抗体检测。结果职业人群中H9亚型抗体阳性率为10.7%,一般人群H9亚型抗体阳性率为2.2%,未检出H5亚型抗体。结论H9亚型在职业人群存在的隐性感染远高于一般人群,提示加强家禽接触人群的监测对于禽流感的预警和防制有非常重要的意义。更多还原

【Abstract】 Objective To investigate the infection status of H5 and H9 influenza viruses in occupational population in Guangzhou in 2006,and provide scientific basis for the disease control and prevention of avian influenza.Methods 831 serum samples from occupational population(work for the feed,sale and slaughter of poultry),and 735 serum samples from general population in 12 districts of Guangzhou city were collected,and the antibodies against H5 and H9 were detected by hemagglutination inhibition test.Results The antibody positive rate for H9 was 2.2% in the general population and 10.7% in occupational population.No positive samples for H5 had been detected in both populations.Conclusion The latent infection rate of H9 avian influenza virus is higher in occupational population than that in the general population,which indicates the surveillance in occupational population is very important for predicting and prevention of the epidemic of avian influenza.更多还原
