内蒙古自治区巴彦淖尔市人感染H7N9禽流感病例的流行病学调查

Epidemiological investigation of the case of human infection with avian influenza A (H7N9) virus in Bayannur in Inner Mongolia

  • 摘要: 目的 通过对内蒙古自治区巴彦淖尔市人感染H7N9禽流感病例的流行病学调查,为进一步科学防控提供依据。方法 运用描述流行病学方法对患者、密切接触者进行流行病学调查,并采集密切接触者咽拭子和鸡舍笼具表面擦拭标本、鸡粪便、饮用水等外环境的标本进行H5、H7、H9病毒核酸检测。结果 确诊1例人感染H7N9禽流感病例,该病例有与活禽鸡接触的暴露史。经治疗好转出院。21名密切接触者经过最长潜伏期的医学观察,未出现发热等呼吸道症状。2周强化监测,未发现人感染H7N9禽流感病例。外环境标本监测,甲型流感病毒通用检测均为阴性。患者在饲养家禽时未采取防护措施,当地医务人员缺乏相关诊断和处置能力。结论 患者有活禽暴露史,应加大对群众的宣传力度,同时加强医务人员的培训。

     

    Abstract: Objective To understand the epidemiological characteristics of the first human infection with avian influenza A (H7N9) virus in Bayannur, Inner Mongolia, and provide evidence for the prevention and control of human infection with H7N9 virus. Methods Using descriptive epidemiology method, epidemiological investigation was conducted in patient and close contacts. The throat swabs of close contacts, cage surface swabs, chicken feces samples and drinking water were collected to detect H5, H7 and H9 virus nucleic acids.Results One case of human infection with H7N9 virus was confirmed. The case had a definite history of exposure to live poultry and was discharged from the hospital after treatment. Twenty one close contacts had no respiratory symptoms, such as fever, after the longest incubation period. Intensive surveillance for 2 weeks found no other human infection with H7N9 virus cases. The detection results of all external environment samples were negative. The patient took no protective measures when raising poultry, and the local medical personnel were unfamiliar with diagnosis and response of human infection with avian influenza virus.Conclusion The source of infection might be the exposure to live poultry, so it is necessary to strengthen the health education in local peple and professional training in medical staff.
