目的了解曲靖市流行性感冒(简称流感)流行动态,为及时预警流感活动强度和流感的防治提供科学依据。方法收集2014年第1周-2015年第53周曲靖市流感监测资料和病原学数据,分析流感样病例占门诊病例的百分比、病毒分离率及流感病毒各型别构成及变化规律。结果 2014年-2015年国家哨点医院曲靖市第一人民医院流感监测结果,就诊病例共计521 537例,其中流感样病例12 072例,占监测就诊病例的2.31%。共采集流感样病例咽拭子标本2 354份,分离出流感病毒122份,分离率为5.18%,其中甲型74份,主要为H3N2亚型,占60.66%;乙型48份,占39.34%。结论 2014年-2015年曲靖市流感处于相对平稳状态,15岁~年龄组是此流行期的高危人群,流感样病例监测和病原学监测,可及时反映流感活动状况,对掌握该地区流感流行规律和防控有重要意义。
Objective To understand the prevalence of influenza in Qujing city and to provide a scientific basis for early warning of the intensity of influenza activity and prevention and treatment of influenza. Methods Influenza surveillance data and etiological data were collected from the first week of 2014 to the 53rd week of 2015 in the city of Qujing. The percentages of outpatients with influenza-like illness, the isolation rate of influenza virus and the composition and variation of each type of influenza virus were analyzed. Results From 2014 to 2015, the results of influenza surveillance in Qujing First People’s Hospital of National Sentinel Hospital included 521 537 cases, of which 12 072 cases were influenza-like cases, accounting for 2.31% of the cases monitored. A total of 2 354 swab samples of influenza-like cases were collected and 122 influenza viruses were isolated with a separation rate of 5.18%, of which 74 were type A, mainly H3N2 subtypes (60.66%), 48 (type B), accounting for 39.34% . Conclusions From 2014 to 2015, the flu in Qujing City was relatively stable. The 15-year-old group was the high-risk population in this epidemic period. Influenza-like case surveillance and etiological monitoring could reflect the influenza activity status in time. And prevention and control are important.
