摘要
目的分析平顶山市2008-2017年手足口病(HFMD)的流行特征和病原谱。方法利用中国疾病预防控制信息管理系统收集平顶山市2008-2017年HFMD发病和病原学数据,进行描述性流行病学分析。结果平顶山市2008-2017年共报告HFMD 47 999例,年平均发病率为105.02/10万;≤5岁儿童病例占97.58%;4-6月份报告病例占55.00%;新华区、湛河区和卫东区3个主城区病例占42.49%。在2 903例实验室确诊病例中,肠道病毒71型(EV71)、柯萨奇病毒A16型(CV-A16)、其他肠道病毒感染分别占54.01%、17.05%、28.94%;在1 269例实验室确诊的重症病例中分别占74.94%、6.38%、18.68%。结论平顶山市HFMD发病呈现明显的年龄、季节和地区分布特征,以EV71和其他肠道病毒感染为主。需重点加强主城区、≤5岁儿童的HFMD防控和肠道病毒分型检测。
Objective To determine epidemiological characteristics and pathogen spectrum of hand, foot, and mouth disease(HFMD) in Pingdingshan city of Henan province during 2008-2017. Methods We collected HFMD case and etiological data in Pingdingshan during 2008-2017 as reported to the National Notifiable Disease Reporting System for a descriptive epidemiological analysis. Results A total of 47 999 HFMD cases were reported in Pingdingshan during2008-2017, for an average incidence of 105.02 per 100 000 population. 97.58% of cases were ≤5-year-old children,55.00% of cases were reported f rom April to June, and 42.49% of cases were reported by three urban districts-Xinhua, Zhanhe, and Weidong. Infections with enterovirus type 71(EV71), Coxsackie virus type A16(CV-A16), and other enteroviruses accounted for 54.01%, 17.05%, and 28.94% of 2 903 lab-confirmed cases, respectively, and 74.94%,6.38%, and 18.68% of 1 269 lab-confirmed severe cases. Conclusions The HFMD incidence showed clear characteristics in population, season, and region, with predominant infections with EV71 and other enteroviruses. We should focus on HFMD control and enterovirus detection for ≤5-year-old children and in central urban areas.
