目的 分析阜阳市首例人感染H5N6禽流感轻症患儿流行病学特征,为做好病例诊治及防控工作提供参考。方法 调查人感染H5N6禽流感患儿发病就诊情况、密切接触者、可疑禽类及活禽市场环境情况,采集患儿及其涉及的人群、活禽和环境标本并进行流感病毒检测,应用描述性流行病学方法进行分析。结果 阜阳市1例人感染H5N6禽流感患儿为流感常规监测发现,发病约10 h服用磷酸奥司他韦,约20 h症状消失,密切接触者无感染,可疑活禽摊位环境标本检测出现H5型禽流感病毒。结论 患儿有活禽市场环境暴露史,早发现早治疗,对减轻病情,提高治疗效果,具有重要意义,未发现人传人现象。
Abstract
Objective To analyze the epidemiological characteristics of the first mild case of child infection with avian influenza A(H5N6) virus in Fuyang City,and to provide reference for case diagnosis,treatment,prevention and control. Methods The medical service and close contacts of the child,suspected poultry,live poultry market environment were investigated.The specimens of the child,close contacts,suspected live poultry and market environment were collected and tested for influenza virus.Descriptive epidemiological methods were used for analysis. Results A case of child infection with avian influenza A(H5N6) virus in Fuyang City was detected by routine surveillance of influenza.The patient took oseltamivir phosphate about 10 hours after onset of illness and recovered from symptoms about 20 hours after onset.The close contacts were not infected.Avian influenza (H5) virus was detected in environmental specimens of suspected live poultry market. Conclusion The child has a history of exposure to live poultry market environment.Early detection and treatment are of great significance in reducing the severity of the disease and improving the therapeutic effect.Human-to-human transmission has not been found.
