目的了解2016年苏州市高新区手足口病流行病学特征,为今后手足口病预防控制工作提供依据。方法采用描述流行病学方法对传染病报告信息管理系统报告的2016年苏州市高新区手足口病病例进行分析。结果 2016年苏州市高新区共报告手足口病病例1 972例,发病率为267.79/10万;重症病例有10例,占0.51%,无死亡病例;全年发病呈现夏季和秋冬季双峰流行的特征;以5岁及以下儿童发病为主,占病例总数的86.92%,散居儿童居多;确诊病例中以其他肠道病毒感染为主,占55.10%;确诊重症病例中EV71阳性比例显著高于确诊普通病例,差异有统计学意义(χ~2=20.38,P<0.05)。结论 2016年苏州市高新区手足口病发病率较历年上升明显,有较明显的季节性发病高峰,流行的病毒优势株非EV71,5岁及以下的散居儿童和幼托机构儿童是防控重点人群。疾控部门要进一步加强手足口病病原学监测,提高除EV71和Cox A16以外其他肠道病毒病原种类检测和鉴定能力,及时发现流行的病毒优势株变化情况;在5岁及以下儿童中推广接种EV71灭活疫苗;积极开展健康教育工作,注重培养儿童和家长良好的卫生习惯,提高自我防病的意识。
Objective To understand the epidemiological characteristics of hand-foot-mouth disease in high-tech zones in Suzhou City in 2016 and provide the basis for future prevention and control of hand-foot-mouth disease. Methods Descriptive epidemiological methods were used to analyze HFMD cases in Suzhou Hi-tech Zone reported by Infectious Disease Reporting Information Management System in 2016. Results A total of 1 972 cases of hand-foot-mouth disease were reported in Suzhou Hi-tech Zone in 2016 with an incidence of 267.79 / 100 000; 10 cases were severe cases, accounting for 0.51%, with no deaths; the annual incidence showed a double peak in summer and autumn and winter The incidence of EV71 in severe cases was significantly higher than that in other cases (55.10%). The incidence of EV71 in severe cases was significantly higher than that of EV71 The diagnosis of common cases, the difference was statistically significant (χ ~ 2 = 20.38, P <0.05). Conclusion The prevalence of HFMD in Suzhou High-tech Zone in 2016 was significantly higher than that in previous years, with obvious seasonal peak. The prevalence of non-EV71 virus-dominant children was the focus of prevention and control for diaspora and preschool children aged 5 and below crowd. Disease control departments should further strengthen the hand foot and mouth disease etiology monitoring, improve EV71 and Cox A16 in addition to other enteric virus pathogen species detection and identification capabilities, and timely detection of the prevalence of the dominant virus strains change; promotion of vaccination in children 5 years of age and below EV71 inactivated vaccine; actively carry out health education, focusing on developing good health habits of children and parents, improve self-awareness of disease prevention.
