摘要
目的对邢台市2014年流行性感冒（简称流感）监测结果进行分析,了解流感的流行趋势、病原学变化规律,为以后流感预防控制工作提供科学依据。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,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 2014年邢台市流感监测哨点医院共监测门、急诊就诊病例120 122例,ILI 2 565例。病例以25岁~年龄组为主（35.32%）,60岁~年龄组最少（7.72%）,其中0岁~和25岁~年龄组所占比例较大。2014年共检测ILI标本1 336份,核酸阳性328份,阳性率24.55%。其中B型流感病毒核酸阳性75份,A型H3N2阳性175份,新A型H1N1阳性77份,B型和新A型H1N1混合阳性1份。5岁~年龄组核酸阳性率最高。结论邢台市2014年流感均为散发,无流感疫情暴发。2014年邢台市流行的流感病毒有新A型H1N1、A型H3N2、B型,其中以A型H3N2流感流行为主。
[Objective]To analyze the results of influenza surveillance in Xingtai City in 2014,understand the epidemic trend and pathogenic change law,and provide the scientific basis for influenza prevention and control work in future. [Methods]The influenza-like illness（ILI） cases were monitored in sentinel hospital,the ILI oropharyngeal swabs were collected and sent to influenza surveillance network laboratory,and the nucleic acid detection was performed by real-time RT-PCR within 24 hours,to isolate and identify the influenza virus.[Results]A total of 120 122 cases were monitored in outpatient department and emergency department in sentinel hospitals of Xingtai City in 2014,and there were 2565 ILI cases. 35.32% of cases were people aged 25-60 years old,patients over 60 years old accounted for only 7.72%,and 0-5 and 25-60 year-old age groups accounted for the greatest proportion. A total of ILI samples were detected in 2014,and 328 were positive for nucleic acid of influenza virus,with the positive rate of 24.55%. There were 75 cases of influenza B,175 cases of influenza A（H3N2）,77 cases of new influenza A（H1N1）,and 1 case of coexistence of influenza B and new influenza A（H1N1）. The positive rate in 5-15 year-old age group was the highest.[Conclusion]The influenza cases in Xingtai City in 2014 are sporadic,and there is no outbreak. The main strains of influenza in Xingtai City in 2014 include new influenza A（H1N1）,influenza A（H3N2） and influenza B,and influenza A（H3N2）is the dominant strain.
