广东省1988-1998年流感流行与监测分析

目的：了解广东地区流感流行情况,探讨流行特征，提供防治建议。方法：建立全省流感监测网，进行流行病学学调查。结果：1988－1998年流感流行高峰在每年的3－7月，其中7年流行优势毒株为H3N2毒株，由于发生明显的血清学抗原漂移，1996年H3N2毒株引起广东地区流感流行。1998年禽流感监测中，从9例患者流感鼻咽拭子中分离到H9N2流感毒株，与此同时，从鸡 发离到禽H9N2毒株。结论：广东地区每年只有一个流感流行峰，目前H3N2流感毒株仍是广东地区的优秀毒株，流感H9N2毒株对人类的致病性值得进一步探讨。

Analysis on Influenza Epidemic and Surveillance in Guangdong between

Objective] To investigate the epidemiological characteristics of influenza and provide the control measures [Methods] To establish the influenza surveillance network and investigate the influenza epidemic and pathogen [Results] The epidemic peaks were annually on March to July in Guangdong in 1988-1998,The epidemic in 7 years was predominated by H 3N 2 strain The outbreak of influenza occurred in 1996 because of the remarkable antigenic drift of H 3N 2 strain The H 9N 2 strains were isolated from 9 patients and the chicken in 1998 [Conclusion] There is one epidemic peak annually in the province The epidenic is predominated by H 3N 2 strain in Guangdong province.It is worth to research the pathogenicity of influenza H 9N 2 in the future.
