目的分析2009-2010年平顶山市手足口病流行特征,为制定有效防控措施提供依据。方法收集2009-2010年平顶山市疾病监测报告信息系统报告的手足口病病例资料进行描述性流行病学分析。结果 2009和2010年平顶山市分别报告手足口病病例6 043例和10 040例,重症病例为271例和1 917例,死亡病例2例和9例;发病率为121.24/10万和200.26/10万,死亡率为0.04/10万和0.18/10万。2009年和2010年市区的发病率均高于郊县,差异有统计学意义(P<0.001)。2009年和2010年的发病高峰集中在3～4月和3～5月。2009-2010年手足口病病例均以3岁及以下儿童为主;男性发病高于女性;散居儿童发病较多。2个年度手足口病实验室确诊病例均以EV71感染为主,且2009年和2010年的病原学分布差异有统计学意义(P<0.001)。结论 2010年平顶山市手足口病流行强度大于2009年,市区发病率高于郊县,2009-2010年手足口病病原学构成比例发生转变。加强疫情和病原学监测,做好3岁及以下散居儿童手足口病防控工作是手足口病防控工作的重点。
Objective To analyze the epidemiological characteristics of HFMD in Pingdingshan City from 2009 to 2010 and provide the basis for effective prevention and control measures. Methods Descriptive epidemiological analysis of hand, foot and mouth disease cases reported by the information system of Pingdingshan Disease Surveillance Report 2009-2010 was collected.

There were 271 cases and 1 179 cases of severe cases, 2 cases of death and 9 cases of death. The incidence rates were 121.24 / 100000 and 200.26 / 10 The death toll was 0.04 / 100,000 and 0.18 / 100,000 respectively. The prevalence rates in urban areas in 2009 and 2010 were higher than those in suburban counties, the difference was statistically significant (P <0.001). The peak incidence in 2009 and 2010 concentrated in March to April and March to May. 2009-2010 cases of hand, foot and mouth disease are mainly children aged 3 and below; men than women; incidence of scattered children more. EV71 infection was the main cause of laboratory diagnosis of HFMD in 2 years, and there was significant difference in the distribution of etiology between 2009 and 2010 (P <0.001). Conclusion The prevalence of HFMD in Pingdingshan in 2010 is greater than that in 2009, and the incidence in urban areas is higher than that in suburbs. The proportion of HFMD in 2009-2010 is changing. Strengthens the epidemic situation and the etiology monitoring, does the handicap foot mouth disease prevention and control work in the handicapped mouth disease to control 3 years of age children and less than 3 year old and below is the key point of hand foot and mouth disease prevention work.
