摘要
目的了解邢台市流行性感冒（流感）的流行趋势、病原学变化规律,为以后流感防控工作提供科学依据。方法哨点医院对流感样病例（ILI）进行监测,并按要求采集ILI咽拭子标本运送至流感监测网络实验室,流感监测网络实验室在24 h内采用实时反转录聚合酶链反应（Real-time RT-PCR）法进行核酸检测,并完成流感病毒的分离鉴定。结果 2013年邢台市流感监测哨点医院共监测门、急诊就诊病例102 810例,ILI 1 873例。病例以0岁~年龄组为主（30.54%）,60岁~年龄组最少（10.84%）,其中0岁~和25岁~年龄组所占比例较大。2013年共检测流感样病例标本938份,核酸阳性70份,阳性率7.46%。其中B型流感病毒核酸阳性1份,A型H3阳性27份,新A型H1N1阳性41份,A型未分型1份。结论邢台市2013年流感均为散发,无流感疫情暴发。2013年邢台市流行的流感病毒有新A型H1N1、A型H3、B和A型未分型,其中以新A型H1N1流感流行为主。
[Objective]To analyze the epidemic characteristics and pathogenic regularity of influenza in Xingtai City, provide the scientific basis for future prevention and control work of influenza.[Methods]The surveillance of influenza like illness （ILI） cases was conducted in sentinel hospitals. The throat swabs samples were collected from ILI cases, to detect the viral nucleic acid by Real-time RT-PCR within 24 hours in influenza network laboratory. Meanwhile, the isolation and identification of influenza virus were completed.[Results]A total of 102 810 patients were surveyed in out patient and emergency department in sentinel hospitals of Xingtai City in 2013, and 1 873 ILI cases were detected. The majority of cases were children aged 0-5 years old （30.54%）, while the cases in over 60 year-old age group was the least（ 10.84% ）, and the cases mainly occurred in people aged 0-5 years old and 25-60 years old. 70 positive samples were detected in 938 samples in 2013, with the positive rate of 7.46%, including 1 sample of influenza B, 27 samples of influenza A（H3）, 41 samples of new influenza A（H1NI ）, and 1 sample of undifferentiated influenza A.[Conclusion]All influenza cases are sporadic in Xingtai City in 2013, and there is no influenza outbreak. The main viruses include new influenza A（H1N 1 ）, influenza A（H3）, influenza B and undifferentiated influenza A, and the new influenza A（H1NI ） is the dominant strain.
