目的分析2008-2013年朝阳区手足口病流行特征。方法采用描述流行病学方法,对朝阳区2008-2013年手足口病监测数据进行分析。结果 2008-2013年朝阳区报告病例数分别为2 410例、3 294例、5 779例、4 480例、5 192例和5 767例,报告重症数分别为24例、16例、149例、70例、81例和15例,报告发病率分别为88.82/10万、116.94/10万、198.14/10万、126.38/10万、142.62/10万和154.43/10万。流动人口聚集的地区报告病例数较多,发病高峰为5-7月。病例中5岁以下儿童占88.0%,男女性别比为1.55∶1。病例中散居儿童和托幼儿童分别占59.0%和36.6%。2 745份生物样本中,阳性率为52.0%(1 427份),EV71和Cox A16分别占阳性标本的35.0%和33.6%。结论朝阳区手足口病疫情呈高发的态势,尤以城乡结合部为主,发病集中在夏秋季,好发于5岁以下男性幼儿。EV71和Cox A16是朝阳区手足口病的主要致病病原,与北京市手足口病流行趋势一致。
Objective To analyze the epidemic characteristics of HFMD in Chaoyang District from 2008 to 2013. Methods Descriptive epidemiological methods were used to analyze the monitoring data of hand-foot-mouth disease in Chaoyang District from 2008 to 2013. Results The number of reported cases in Chaoyang District in 2008-2013 were 2410, 3494, 5797, 4480, 5192 and 5767 respectively. The reported severe cases were 24, 16 and 149, respectively. 70 cases, 81 cases and 15 cases. The reported incidence rates were 88.82 / 100000, 116.94 / 100000, 198.14 / 100000, 126.38 / 100000, 142.62 / 100000 and 154.43 / 100000 respectively. Floating population gathered in the region reported a larger number of cases, the peak incidence of May-July. Cases of children under 5 years accounted for 88.0%, male to female ratio was 1.55: 1. In the cases, scattered children and child care children accounted for 59.0% and 36.6% respectively. Among 2 745 biological samples, the positive rate was 52.0% (1 427), while EV71 and Cox A16 accounted for 35.0% and 33.6% of the positive samples, respectively. Conclusion The HFMD epidemic in Chaoyang District showed a high incidence, especially in urban-rural areas. The incidence was concentrated in summer and autumn, which occurred in young children under 5 years of age. EV71 and Cox A16 are the main pathogenic pathogens of hand-foot-mouth disease in Chaoyang District, consistent with the epidemic trend of hand-foot-mouth disease in Beijing.
