摘要
目的分析2017—2021年广东省佛山市高明区流感流行特征及影响因素,为佛山市高明区预防流感提供理论依据。方法根据佛山市高明区的流感资料,对流行病学特征进行描述性分析,根据流感持续时间为结局变量,以采取措施的时间、聚集场所、流感病毒分型、流感疫苗接种情况等为自变量,采用logistic回归分析流感发生持续时间的影响因素。结果2017—2021年佛山市高明区累计报告流感病例5782例,男性占比(51.45%)高于女性(48.55%);流感发病年龄主要在3~8岁(50.47%);发病季节主要集中在冬季(69.82%);2017—2021年佛山市高明区流感病例涉疫场所主要为幼托机构(49.44%)和小学(29.78%);引起流感暴发的流感病毒主要甲型H1N1系(48.88%)和乙型Yamagata系(23.11%);多因素logistic回归分析显示采取措施的时间、疫苗接种情况是流感疫情持续时间的保护因素。结论佛山市高明区流感主要集中在3~8岁儿童,以冬季高发,幼托机构和小学是流感高发场所,应倡导学生积极接种疫苗,快速采取措施,可降低流感暴发的持续时间。
Objective To analyze the epidemic characteristics and influencing factors of influenza in Gaoming District of Foshan City from 2017 to 2021,and provide theoretical basis for influenza prevention in Gaoming District of Foshan City.Methods According to the influenza data in Gaoming District of Foshan City,descriptive analysis was made on the epidemiological characteristics.With the duration of influenza as the outcome variable and the time of taking measures,gathering place,influenza virus typing and influenza vaccination as independent variables,logistic regression was used to analyze the influencing factors of the duration of influenza.Results From 2017 to 2021,5782 influenza cases were reported in Gaoming District of Foshan City,with male(51.45%)higher than female(48.55%).The age of influenza onset was mainly 3-8 years old(50.47%).The incidence season was mainly concentrated in winter(69.82%).From 2017 to 2021,influenza cases in Gaoming District of Foshan were mainly in nursery care children(49.44%)and primary schools(29.78%).The influenza viruses that caused the outbreak were mainly A H1N1(48.88%)and B Yamagata(23.11%).Multivariate logistic regression analysis showed that the time of action and vaccination status were protective factors for the duration of influenza epidemic.Conclusion In Gaoming District of Foshan,influenza is mainly concentrated in children aged 3 to 8 years old,especially in winter.Children in kindergartens and primary schools are the places of high incidence of influenza.It is necessary to advocate active vaccination of students and take rapid measures to reduce the duration of influenza outbreak.
