Analysis of notifiable infectious diseases in Zhejiang Province in 2023

目的分析2023年浙江省法定传染病疫情流行特征,为加强传染病防制提供依据。方法通过中国疾病预防控制信息系统传染病监测系统收集2023年浙江省法定传染病报告资料,按法定传染病分类和传播途径分析发病率和死亡率,描述性分析传染病疫情的流行特征。结果2023年浙江省报告法定传染病30种,发病2955699例,报告发病率为4493.93/10万;死亡427例,报告死亡率为0.6492/10万。报告法定传染病突发事件679起,发病26514例,死亡1例(狂犬病);主要发生在学校和托幼机构,621起占91.46%。甲类传染病报告霍乱1例,无死亡病例报告;乙类传染病报告22种,报告发病率为552.46/10万,报告死亡率为0.6447/10万。丙类传染病报告8种,报告发病率为3941.48/10万,报告死亡率为0.0046/10万。按传播途径分析,呼吸道、肠道、血源及性传播、自然疫源及虫媒传染病报告发病率分别为4028.67/10万、381.59/10万、81.15/10万和1.35/10万。流行性感冒(3561.78/10万)、新型冠状病毒感染(423.77/10万)报告发病率较高,艾滋病(0.4774/10万)和肺结核(0.1308/10万)报告死亡率较高。结论2023年浙江省呼吸道、肠道传染病发病率较高,学校和托幼机构是主要发病场所。

Objective To investigate epidemiological characteristics of notifiable infectious diseases in Zhejiang Province in 2023,so as to provide the evidence for strengthening prevention and control of infectious diseases.Methods Data pertaining to notifiable infectious diseases reported in Zhejiang Province in 2023 were retrieved from the Infectious Dis⁃ease Surveillance System of Chinese Disease Prevention and Control Information System.The incidence and mortality were analyzed according to the classification of notifiable infectious diseases and transmission routes,and epidemiologi⁃cal characteristics of infectious diseases were descriptively analyzed.Results Thirty types of notifiable infectious diseas⁃es with 2955699 cases and 427 deaths were reported in Zhejiang Province in 2023,with a reported incidence rate of 4493.93/10^(5)and a reported mortality rate of 0.6492/10^(5).A total of 679 notifiable infectious disease emergencies were reported,with 26514 cases and 1 case death(rabies).The emergencies mainly occurred in schools and preschool insti⁃tutions,with 621 cases accounting for 91.46%.There were 1 case of cholera reported in class A notifiable infectious diseases and no death,22 types of class B notifiable infectious diseases,with a reported incidence rate of 552.46/10^(5)and a reported mortality rate of 0.6447/10^(5),and 8 types of class C notifiable infectious diseases,with a reported inci⁃dence rate of 3941.48/10^(5)and a reported mortality rate of 0.0046/10^(5).The incidence rates of respiratory,intestinal,blood-borne and sexually transmitted,natural and insect-borne infectious diseases were 4028.67/10^(5),381.59/10^(5),81.15/10^(5)and 1.35/10^(5),respectively,according to transmission routes.Influenza(3561.78/10^(5))and COVID-19(423.77/10^(5))report⁃ed the highest incidence,and AIDS(0.4774/10^(5))and tuberculosis(0.1308/10^(5))reported the highest mortality.Conclu⁃sion The incidence rates of respiratory and intestinal infectious diseases were high in Zhejiang Province in 2023,and schools and preschool institutions were the main places of diseases occurred.
