摘要
目的通过对吉林省2023-2024年流感样病例(ILI)监测结果进行分析,为本省ILI的预防和控制提供科学依据,同时为下一年的疫苗接种提供指导。方法通过检索中国流感监测信息系统,获得吉林省ILI的流行病学数据,对ILI的年龄分布、地区分布以及时间分布进行统计学分析。在吉林省内13家国家级哨点医院采集咽拭子样本进行核酸检测,了解吉林省ILI的病原学特征。结果2023年4月-2024年3月,吉林省13家国家级哨点医院门急诊就诊病例总数为4399424例,424156例(9.64%)为ILI。病例主要集中在15岁以下儿童,5~<15岁组最多为156237例,0~<5岁组为142555例,不同年龄组之间差异有统计学意义(χ^(2)=28183.195,P<0.05)。在吉林省9个市州中通化市、松原市和延边州的ILI比例相对较高,分别为19.14%、18.29%和18.26%。10月-次年3月为ILI的高发阶段,流行高峰出现在12月。采集的15483份咽拭子中,阳性样本3742份(24.17%),其中新型冠状病毒1703份(11.0%),流感病毒2061份(13.31%)。结论15岁以下儿童是ILI的易感人群,冬春季为ILI的高发时期,建议此类人群在每年9-10月接种流感疫苗以预防ILI流行。
Objective To provide scientific basis for the prevention and control of influenza-like illness(ILI)in Jilin province,and provide guidance for vaccination in the next year by analyzing the surveillance results of ILI in Jilin province from 2023 to 2024.Methods By retrieving the Chinese influenza surveillance information system,epidemiological data of ILI in Jilin province were obtained,and statistical analysis was conducted on the age distribution,regional distribution and time distribution of ILI.Collected throat swab samples from 13 national sentinel hospitals in Jilin province for nucleic acid testing to understand the pathogenic characteristics of ILI in Jilin province.Results From April 2023 to March 2024,the total number of outpatient and emergency treatment cases in 13 national sentinel hospitals in Jilin province was 4399424,with 424156 cases(9.64%)were ILI.These cases were mainly concentrated in children under 15 years old,with a maximum of 156237 cases in the 5-<15 age group and 142555 cases in the 0-<5 age group(χ^(2)=28183.195,P<0.05).Among the 9 cities in Jilin province,Tonghua city,Songyuan city and Yanbian prefecture have relatively high ILI proportion,at 19.14%,18.29%and 18.26%,respectively.The period from October to March of the following year was the high incidence stage of ILI,with the peak appeared in December.Among the 15483 throat swabs collected,3742(24.17%)were positive,including 1703(11.0%)for SARS-CoV-2 and 2061(13.31%)for influenza virus.Conclusions Children under the age of 15 were susceptible to ILI,and winter and spring were the peak periods for ILI.Influenza vaccination should be strengthened in September to October every year to prevent the outbreak of ILI.
