摘要
目的探讨2016年1月至2018年12月云南省文山州流感病例及病原学的流行特征,为制定流感防制策略提供科学依据。方法对2016年1月至2018年12月文山州流感监测的流感样病例(ILI)监测资料和实验室检测结果进行分析。结果2016年1月至2018年12月文山州哨点医院共报告的ILI%平均为1.91%,3 a报告的ILI%差异有统计学意义(χ^2=29.660,P<0.05)。ILI%高峰出现于7~8月和11月~次年1月,同一年度不同月份ILI%差异均有统计学意义,P值均<0.05。3a共采集标本3130份,分离毒株402株,阳性率12.48%,2016年、2017年的优势株为甲型H1N1、H3N2和BV,2018年优势株为甲型H1N1。结论流感病毒活动和流感样病例数之间呈正相关,文山州流感疫情高峰期为夏季和冬季。不同亚型的毒株交替占优势。流感样病例监测已成为人禽流感病例早发现、早诊断的关键途径。
Objective To explore the epidemiological characteristics of influenza cases and pathogens in Wenshan Prefecture of Yunnan Provincein 2016-2018,and provide scientific basis for the prevention of influenza.Me thods The data of epidemiology and etiology of influenza-likeillness(ILI)in Wenshan Prefecturein2016-2018 were collected and analyzed.Re s ults The average percentage of the number of ILI cases accounted for total outpatient was 1.91%in 2016-2018,and the peaks of epidemic of influenza were from July to August and November to January at the next year.3130 influenza specimens were collected in the influenza serveillance hospitals of Wenshan Prefecture,402 influenza virus strains were obtained,the positive rate was 12.48%.The dominant strains were A(HN1),H3 N2 and BV in 2016 and 2017,and A(HN1)in 2018.Conclus ions There is a positive correlation between influenza virus activity and influenza like cases.The peak of influenza in Wenshan Prefecture is in summer and winter.Various subtypes of the virus are dominant alternately.Influenza-like surveillance has become a key way for early detection and diagnosis of human avian influenza cases.
