摘　　要：目的对湖北省松滋市3份、公安县1份人感染H7N9禽流感外环境阳性样本感染来源开展调查,总结两起事件成功处置经验。方法2017年10月至2018年4月,按照《湖北省外环境H7亚型禽流感病毒分布应急监测方案》,对检出人感染H7N9禽流感病毒的外环境场所的感染来源进行调查,并严格落实“扑杀-消毒-关闭-溯源-限制”5项核心控制措施。结果松滋市人感染H7N9禽流感外环境感染来源于X省W养殖场可能性大;公安县人感染H7N9禽流感外环境感染来源不明。两起事件发生后,在当地政府主导的人感染H7N9禽流感联防联控指挥部的有力指挥下,5项核心措施均得到切实落实,未发生人间疫情。结论详细的溯源调查为采取科学防控对策提供依据,5项核心控制措施能有效处置人感染H7N9禽流感外环境阳性事件。Objective To investigate the infection source of 4 H7N9 avian influenza virus environmental infection samples,3 from Songzi,City,and 1 from Gongan County,and to summarize successful experience in the treatment of the two positive external environments of human infected H7N9 avian influenza A virus. Methods From October 2017 to April 2018,a traceability investigation was conducted to identify the source of infection in the external environment where human infection with avian influenza A (H7N9) was detected,according to the Emergency Monitoring Plan for H7 Subtype Avian Influenza Virus Outbreaks in the Outer Environment of Hubei Province. The five core control measures of “Culling-Disinfection-Close-Tracking-Restriction" were strictly implemented. Results The external environment positive sample of H7N9 in Songzi City was highly likely to originate from W farm of X province;the external environment positive sample of H7N9 in Gongan County was unknown. After the occurrence of the two incidents,under the strong command of the local government-led H7N9 Joint Prevention and Control Working Group,the five core measures were effectively implemented and no human epidemic occurred. Conclusion Detailed traceability investigations provide scientific basis for the prevention and control countermeasures. The five core control measures can effectively deal with human infected H7N9 avian influenza positive external environment events.
