目的了解石棉县手足口病流行特征及病原体分布情况,为制定防制措施提供科学诊据。方法对石棉县2010～2012年报告的手足口病监测资料进行描述性流行病学分析。结果 2010～2012年共报告发病病例263例,无死亡和重症病例发生,年平均报告发病率为71.23/10万,以2010年发病最高;发病呈现双峰型,每年11月为发病最高峰,4～7月为次高峰,多发生于5岁以下儿童,占发病总数的95.05%,男性多于女性,多为散居儿童,占发病总数的83.65%;病原体以CcxA16型和EV71型为主要流行毒株,不同血清型间无交叉免疫。结论石棉县手足口病的发病存在明显的地区、季节、性别及年龄差异,需加强散居儿童、托幼儿童监管人员防控知识宣传,同时加大疫情监测、指导、督查力度,及时处置散发病例和聚集性病例,有效控制疫情和突发公共卫生事件的发生。
Objective To understand the epidemiology and pathogen distribution of HFMD in Shimian County and provide scientific evidence for the development of control measures. Methods A descriptive epidemiological analysis of hand, foot and mouth disease surveillance data reported in 2010 and 2012 in Shimian County was conducted. Results A total of 263 cases were reported from 2010 to 2012, with no deaths and severe cases. The average annual incidence was 71.23 / 100 000, with the highest incidence in 2010; the incidence was bimodal, with the highest incidence in November each year, From April to July, it was sub-peak, occurred mostly in children under 5 years of age, accounting for 95.05% of the total incidence, more males than females and mostly scattered children, accounting for 83.65% of the total. The pathogens were mainly CcxA16 and EV71 Strain, no cross between different serotypes. Conclusion The incidence of hand, foot and mouth disease in Shimian County is obviously different according to region, season, gender and age. It is necessary to strengthen the publicity on prevention and control of diasporic and child care supervisors, and at the same time increase the monitoring, guidance and supervision of epidemic situation and dispose of the distribution in time Cases and clusters of cases, effective control of the outbreak and public health emergencies.
