The aim of this study was to investigate the effects of vaccination, COVID-19 pandemic and migration of migratory birds on the avian influenza positivity rate in Shangrao City and to predict the future avian influenza positivity rate. Real-time reverse transcription polymerase chain reaction (RT-PCR) was used to detect nucleic acids of avian influenza A viruses. 1795 samples were collected between 2016 and 2022, of which 1086 were positive. In addition, there were seven human cases of avian influenza. The results showed that the positivity rate of H9 subtype in Shangrao City was higher than usual during the COVID-19 pandemic and migratory birds. Predictions suggest that the H9 subtype positivity rate in Shangrao City will be on the rise in the future. In recent years, the H5 positivity rate has gradually increased. Migratory birds and the COVID-19 pandemic have led to an increase in H9 subtype positivity. Therefore, the prevention and control of them should be strengthened.
本研究旨在调查疫苗接种、新冠疫情和候鸟迁徙对上饶市禽流感阳性率的影响，并预测未来禽流感阳性率。采用实时逆转录聚合酶链反应（RT-PCR）检测甲型禽流感病毒核酸。2016年至2022年期间共采集1795份样本，其中1086份呈阳性。此外，还有7例人感染禽流感病例。结果显示，在新冠疫情和候鸟迁徙期间，上饶市H9亚型阳性率高于常年。预测表明，未来上饶市H9亚型阳性率将呈上升趋势。近年来，H5阳性率逐渐上升。候鸟和新冠疫情导致H9亚型阳性率增加。因此，应加强对它们的防控。
