【摘要】：目的分析2010-2016年度陕西省流行性感冒(流感)的流行特征,为全省的流感防控提供科学依据。方法采集全省18家国家级流感监测哨点医院门诊流感样病例(ILI)的鼻咽拭子,用实时荧光聚合酶链式反应(PCR)检测流感病毒核酸,阳性标本进行病毒分离培养,得到的流感毒株用血凝抑制试验(HI)进行鉴定。结果 2010-2016年陕西省流感检测阳性率为15.57%;ILI年龄分布以0~5岁为主(49.62%),流感病毒检测阳性率最高的为5~14岁(23.21%);分离流感病毒2 280株,其中新甲型H1N1 518株,占22.72%;季节性H3 852株,占37.37%;B型Victoria系526株,占23.07%;B型Yamagata系384株,占16.84%。结论陕西省流感病毒表现为各型别交替流行,青少年儿童为易感人群,暴发疫情易发生在流行高峰期,应积极采取综合性防控措施。
[Abstract]:Objective to analyze the epidemic characteristics of influenza (influenza) in Shaanxi province in 2010-2016 and to provide scientific basis for influenza prevention and control. Methods the nasopharynx swabs of 18 national influenza surveillance sentinel hospitals were collected, and the influenza virus nucleic acid was detected by real-time fluorescent polymerase chain reaction (PCR). The positive samples were isolated and cultured. The influenza strain was identified by hemagglutination inhibition test (HIH). Results from 2010 to 2016, the positive rate of influenza detection in Shaanxi Province was 15.57. The age distribution of influenza virus was mainly 49.62 years old. The highest positive rate of influenza virus detection was 50.14 years old and 23.21%, 2 280 strains of influenza virus were isolated, among which 22.722 strains were new type A H1N1, and 3852 strains were seasonal H3,852. There were 526 Victoria strains of B type and 384 Yamagata strains of 23.07B type, accounting for 16.84. Conclusion Influenza virus in Shaanxi Province is characterized by alternating epidemic types, and adolescents and children are susceptible population. The outbreak is likely to occur in the peak period of the epidemic. Comprehensive prevention and control measures should be taken actively.
