摘要
目的:分析成都市郫都区流行性感冒(以下简称流感)的流行病学特征,为郫都区流感的科学防控以及适时调整流感防控策略提供依据。方法:依据中国疾病预防控制信息系统传染病监测相关数据,采用描述性流行病学的方法对2019—2023年郫都区流感流行病学特征进行分析。结果:2019—2023年郫都区共报告流感病例52441例,各年流感发病率依次为723.70/10万、63.76/10万、224.36/10万、357.37/10万、2572.21/10万,总体呈先降后升趋势,发病高峰主要集中在冬、春季节,郫筒街道(1614.96/10万)、红光街道(1049.53/10万)、犀浦街道(822.35/10万)、德源街道(785.85/10万)发病率明显高于郫都区其他街道/镇。流感病例中男女性别比为1.18:1,职业分类以学生为主,占发病总数的40.24%。结论:2019—2023年冬春季为郫都区流感高发期,流感主要发生在城镇区域,病例以男性为主,学生和托幼机构儿童为流感高发人群。针对郫都区流感流行状况,应在冬、春季前加强监测预警和流感趋势预测,做好学校及托幼机构的流感防控工作,同时加强流感疫苗接种和健康宣教,降低流感发病率。
OBJECTIVE To analyze the epidemiological characteristics of influenza in Pidu District from 2019 to 2023,and to provide basis for the scientific prevention and control of influenza and the timely adjustment of influenza prevention and control strategies in Pidu District.METHODS According to the relevant data of infectious disease surveillance in the China Disease Prevention and Control Information System,descriptive epidemiological methods were used to analyze the epidemiological characteristics of influenza in Pidu District from 2019 to 2023.RESULTS From 2019 to 2023,a total of 52441 cases of influenza were reported in Pidu District of Chengdu.The incidence rates of influenza in each year were 723.70/10^(5),63.76/10^(5),224.36/10^(5),357.37/10^(5),and 2572.21/10^(5),showing a trend of first decreasing and then increasing.The peak incidence was mainly concentrated in the winter and spring seasons,and incidence rate of Pitong Street(1614.96/10^(5)),Hongguang Street(1049.53/10^(5)),Xipu Street(822.35/10^(5)),and Deyuan Street(785.85/10^(5))was significantly higher than that of other streets/towns in the jurisdiction.The male to female ratio is 1.08∶1,with students as the main occupational group,accounting for 40.24% of the total incidence rate.CONCLUSION The winter and spring seasons in Pidu District of Chengdu from 2019 to 2023 were the high incidence periods of influenza,mainly occurring in urban areas.The cases were mainly male,and students and children in childcare institutions were the high-risk population for influenza.In response to the influenza epidemic situation in Pidu District,it could strengthen monitoring and early warning as well as influenza trend prediction before the winter and spring seasons,and do a good job in influenza prevention and control in schools and childcare institutions.At the same time,it will strengthen influenza vaccination and health education to reduce the level of influenza incidence.
