摘　　要： 目的了解曲靖市外环境中H5、H7、H9亚型禽流感病毒的分布状况,为曲靖市防控人感染高致病性禽流感提供依据。方法收集2016年1月和2017年1—2月曲靖市采集的外环境禽流感标本,采用RT-PCR方法检测禽流感病毒核酸,阳性者进一步检测H5、H7、H9亚型。监测数据采用Excel和统计学软件进行统计分析。结果 2016年1月和2017年1-2月年共采集126份禽流感外环境标本,检出A型流感病毒核酸阳性标本34份,阳性检出率26.98%。H9亚型检出率最高为15.87%;不同采样场所,活禽交易市场阳性率最高为68.75%;不同采样部位,清洗禽类污水和案板拭子阳性率较高,分别为57.14%、50.00%。结论曲靖市活禽交易市场有禽流感H5、H7、H9亚型存在,感染人的风险较高,加强活禽市场监管力度及宣传教育是防控人感染高致病性禽流感的针对性措施。 Objective This paper tries to understand the distribution of H5, H7 and H9 subtype avian influenza viruses in external environment in Qujing, Yunnan province, and provide evidence for the prevention and control of human infection with avian influenza virus. Methods External environment samples in Qujing from January 2016 and January to February 2017 were collected and avian influenza virus nucleic acid was tested by RT-PCR; the positive samples were exposed to further H5, H7 and H9 subtype testing; the results were analyzed by Excel and software. Results A total of 126 external environment samples were collected from January 2016 and January to February 2017 and 34 were tested of influenza A virus nucleic acid positive,accounting for 26.98%. H9 subtype positive detection rate reached 15.87%; as for different collecting places, the highest positive detection rate occurs in live poultry markets, amounting to 68.75%; as for different collecting places, the highest positive rates occur in poultry washing water and slaughtering board, amounting to 57.14% and 50.00% respectively. Conclusion H5,H7 and H9 subtype avian influenza virus existed in the external environment in Qujing, such as those live poultry markets, and the risk of human infection was high. The targeted measures to prevent and control human infection with avian influenza virus should be strengthened; the management of live poultry markets and more publicity of health education should be increased.
