【摘要】：目的分析江西省首起人感染H7N9禽流感家庭聚集性疫情的流行病学特征,追溯病例的感染来源,并探讨其传播途径。方法运用描述性流行病学方法对病例及其密切接触者进行调查与分析,采用实时反转录-聚合酶链式反应方法对病例和环境标本进行H7N9禽流感病毒核酸检测。结果 2例H7N9禽流感确诊病例为母子关系,经积极救治病愈出院。首发病例(病例A)于2016年4月1日发病,8日返回江西泰和县就诊,发病前1周在福建晋江市有活禽接触和活禽市场暴露史,并在可疑暴露市场标本中检出H7N9禽流感病毒。病例A的密切接触者中,除病例B(病例A母亲)于4月5日发病外,其余密切接触者经医学观察未出现异常。结论 2例病例系江西省首起输入性人感染H7N9禽流感家庭聚集性病例,其感染途径为共同暴露还是有限的人传人尚无明确证据。
[Abstract]:Objective to analyze the epidemiological characteristics of the first family cluster epidemic of human H7N9 avian influenza in Jiangxi Province, and to trace the source of infection. Methods descriptive epidemiology was used to investigate and analyze the cases and their close contacts. Real time reverse transcription-polymerase chain reaction (RT PCR) was used to detect H7N9 avian influenza virus nucleic acid in cases and environmental samples. The first case (case A) fell ill on April 1, 2016, and returned to Taihe County, Jiangxi Province, on the 8th to see a doctor. There was a history of live poultry contact and live poultry market exposure in Jinjiang City, Fujian Province, one week before the onset of the disease. H7N9 avian influenza virus was detected in suspicious exposed market specimens. Among the close contacts of case A, case B (case A mother) developed on April 5. Conclusion the two cases were the first case of imported human infection with H7N9 avian influenza in Jiangxi province, and there was no clear evidence of whether the infection route was co-exposure or limited human-to-human transmission.
