【摘要】：目的分析安徽省合肥市1例同病房密切接触者人感染H7N9禽流感病例的流行病学特征,为制定人感染H7N9禽流感病毒相关防控措施提供参考依据。方法对安徽省合肥市1例同病房密切接触者进行流行病学调查,并采集呼吸道及血液标本应用逆转录聚合酶链反应(RT-PCR)方法检测H7N9病毒核酸。结果病例谷某于2016年12月22日确诊为人感染H7N9禽流感病例,无明显禽类接触史;12月18日该病例曾密切接触同病房闫某,后闫某确诊为H7N9禽流感病例且死亡;2人病毒核酸检测均为同种同源禽流感病毒核酸阳性;除闫某外,其他与谷某密切接触者均未出现人感染H7N9禽流感病毒症状。结论谷某可能为一起医院内感染疫情的续发病例,人传人的可能性大,但单传染力有限,非持续。
[Abstract]:Objective to analyze the epidemiological characteristics of human infection with H7N9 avian influenza in Hefei, Anhui province. Methods Epidemiological investigation was carried out on a case of close contact with the ward in Hefei, Anhui Province, in order to provide a reference for the prevention and control of human infection with H7N9 avian influenza virus. Respiratory and blood samples were collected by reverse transcriptase polymerase chain reaction (RT-PCR). Methods the nucleic acid of H7N9 virus was detected. There was no obvious history of poultry contact. In December 18th, the case had close contact with the ward Yan Mou, after Yan Mou confirmed the H7N9 avian influenza case and died; 2Human virus nucleic acid was positive for homologous avian influenza virus nucleic acid. In addition to Yan, other close contacts with Gu did not show human infection with H7N9 avian influenza virus symptoms. Conclusion Gu Mou may be a further case of hospital infection, the possibility of human-to-human transmission is great. But single contagion is limited and non-persistent.

【正文快照】： H7N9禽流感病毒为一种新型的人禽流感病毒,通常仅在鸟类之间传播,但自2013年以来,中国多地出现了人感染H7N9禽流感的病例[1-2]。研究认为H7N9禽流感病毒主要存在于病禽的分泌物、排泄物、体液和组织中,传染源可能为携带病毒的禽类,可经呼吸道传播,也可通过密切接触病禽的分泌
