【摘要】：目的分析内蒙古自治区赤峰市手足口病流行特征和病原谱变化,为采取有效的防控措施提供参考依据。方法收集国家疾病监测信息管理系统中2012年1月1日—2015年12月31日赤峰市上报的手足口病病历资料和病原学检测结果,分析手足口病的流行特征和病原谱变化情况。结果赤峰市2012—2015年共报告手足口病病例12 637例,年均发病率为72.74/10万,其中2012—2015年手足口病发病率分别为75.38/10万、59.32/10万、106.75/10万、49.43/10万,手足口病发病率较高且呈波浪式变化;发病时间主要集中在5—8月,4个月的手足口病发病例数为9 045例,占总发病例数的71.58%;发病年龄主要集中在1~6岁幼托和散居儿童,男女性别比为1.29:1;2012—2015年手足口病重症病例29例,占发病总数的0.23%,死亡2例,重症病例病死率为6.89%,全部病例病死率为0.02%;2012—2015年采集的2005份样本中,检出肠道病毒733份,阳性率为36.46%,其中EV71、Cox A16、其他肠道病毒分别占28.37%、21.28%、50.34%。Cox A16是2012年赤峰市优势病毒,EV71是2013年赤峰市优势病毒,2014、2015年则以其他肠道病毒为主要病原,赤峰市不同年份病原分布差异有统计学意义(χ~2=225.841,P0.05)。结论赤峰市手足口病发病率较高且呈波浪式变化,病原以EV71、Cox16和其他肠道病毒为优势病原交替流行。
[Abstract]:Objective to analyze the epidemic characteristics and pathogenic spectrum changes of hand, foot and mouth disease in Chifeng City, Inner Mongolia Autonomous region, so as to provide reference for effective prevention and control measures. Methods from January 1, 2012 to December 31, 2015, the medical records of HFMD and the results of etiology were collected in the national disease surveillance information management system, and the epidemic characteristics and pathogeny spectrum of HFMD were analyzed. Results 12,637 cases of HFMD were reported in Chifeng from 2012 to 2015, with an average annual incidence of 72.74% / 100 000. The incidence of HFMD in 2012-2015 was 75.38% / 100 000, respectively. The incidence rate of HFMD was 75.38% / 100 000, respectively. The onset time was mainly in May to August, and the number of HFMD cases in 4 months was 9 045, accounting for 71.58 of the total number of cases, and the age of onset was mainly in 1 or 6 years old young care children and children living in the diaspora. The sex ratio between men and women was 1.29: 1: 2012-2015, accounting for 0.23% of the total number of severe cases of hand, foot and mouth diseases, 2 cases died, and the mortality rate of severe cases was 6.89. The fatality rate of all cases was 0.02% of the 2005 samples collected in 2012-2015, and 733 cases of enterovirus were detected. The positive rate of EV71X Cox A16 and other enteric viruses were 28.37 and 21.28, respectively. Cox A16 was the dominant virus in Chifeng in 2012. EV71 was the dominant virus in Chifeng in 2014 in 2013, and other enterovirus was the main pathogen in 2015. There were significant differences in the distribution of pathogens in different years in Chifeng (蠂 225.841). Conclusion the incidence of HFMD in Chifeng is high and fluctuating.
