摘要
目的了解陕西省2008-2011年手足口病流行病学特征,为进一步防控手足口病提供参考依据。方法采用描述性流行病学方法对陕西省2008-2011年手足口病病例进行分析。结果 2008-2011年陕西省共报告手足口病130 667例,年平均发病率为87.03/10万,重症率0.84%,平均死亡率0.04/10万。西安市年均发病率(177.51/10万)最高,延安市年均发病率(28.28/10万)最低。4-7月为发病高峰。男性发病高于女性,以散居儿童和幼托儿童为主,集中于≤5岁儿童,占93.98%。病原学监测结果显示以EV71为主,占56.48%。重症及死亡病例多发生在4-7月,以≤3岁的散居儿童为主,男性高于女性,病毒主要是EV71型。结论陕西省手足口病发病有明显的地区、季节、年龄、性别和职业特征,因此,做好重点地区、重点时段、重点人群的防控工作尤为重要,同时提示年龄较小、男性儿童是感染EV71后发生死亡病例的危险因素。
Objective To understand the epidemiological characteristics of hand foot and mouth disease （HFMD） in Shaanxi from 2008 to 2011 and provide scientific evidence for the prevention and control of the disease. Methods Descriptive epidemiological analysis was conducted on the incidence data of HFMD reported during this period in Shaanxi province. Results A total of 130 667 HFMD cases were reported with the average annual morbidity of 87. 03/lakh, the severe cases accounted for 0. 84%, and the average annual mortality was 0.04/lakh. The highest average annual morbidity （177.51/lakh） was reported in Xi＇an and the lowest （28.28/1akh） in Yan＇an. The incidence peak occurred during April-July. More cases were distributed in males. Most cases occurred in children outside and in child care settings, the cases in age group ≤5 years accounted for 93.98% of the total. Etiological surveillance indicated that HFMD were mainly caused by EVT1 infection, accounting for 56. 48%. The severe and death cases mainly occurred in children aged 0 -3 years during April-July. Conclusion The incidence of HFMD varied with area, season, age, sex and population in Shaanxi, so it was important to strengthen the targeted prevention and control of HFMD. The analysis also suggested that being young child and male were the risk factors of HFMD death.
