【摘要】 目的分析人感染H7N9禽流感病例的流行病学特征,为有效防控人感染H7N9禽流感提供参考依据。方法对病例开展流行病学个案调查,详细了解其发病和诊疗经过,对密切接触者进行医学观察,运用PCR进行H7N9禽病毒核酸检测。结果结合流行病学史、临床表现和实验室检测结果,确诊死亡病例为贵州省首例输入性人感染H7N9禽流感病例,该病例无明确的禽类接触史。密切接触者中,仅患者配偶和其子出现流感样症状,但均未发现H7N9禽流感病毒感染。结论 H7N9禽流感病毒的感染途径不明,暂无人传人的证据,多部门协作对疫情防控具有积极作用。更多还原

【Abstract】 Objective The study analyzed the epidemiological characteristics of human infected with H7N9 avian influenza, aiming to provide a reference for the effective prevention and control of the disease. Methods An epidemiological case study was conducted on the infected case to assess in detail the patient’s onset, diagnosis, and treatment of the disease; close contacts of the patient were medically observed; and PCR was used to detect the presence of H7N9 avian virus nucleic acids. Results Analysis of the patient’s epidemiology history, clinical manifestation, and laboratory examination results suggested that the confirmed death was the first imported case of human infected with H7N9 avian influenza in Guizhou. The case had no definite history of poultry contact. Among the patient’s close contacts, only his/her spouse and son had exhibited influenza-like symptoms, but neither was found infected with H7N9 avian influenza virus. Conclusion The route of infection with H7N9 avian influenza virus is unclear, with no evidence of human-to-human transmission at this time. Collaboration between multiple agencies is positive for the prevention and control of the epidemic.更多还原
