2013年深圳市光明新区手足口病哨点监测病原检测结果

Pathogen detection results of HFMD sentinel surveillance in Guangming New District of Shenzhen City in 2013

目的分析2013年深圳市光明新区手足口病(HFMD)哨点监测病原检测结果,了解其病原学特征,为HFMD防控提供参考。方法采用描述研究的方法,对2013年深圳市光明新区231例HFMD哨点监测病原学检测阳性病例的流行病学特征进行描述。结果 2013年该区HFMD病例以肠道病毒CVA6亚型感染为主,占69.70%;CVA6的检出4月份开始增多,9月份达到高峰,然后逐渐降低;3岁以下年龄组肠道病毒检出最多,占96.97%;各年龄组肠道病毒的构成差异无统计意义(P>0.05);男女性别比为2.61∶1,不同性别间病原阳性率差异有统计学意义(P<0.05),但病原学构成差异无统计意义(P>0.05);病原学阳性病例以散居儿童为主,占80.95%;不同职业间病原阳性率差异有统计学意义(P<0.05),病原学构成差异亦有统计意义(P<0.05)。结论肠道病毒CVA6亚型是2013年该区HFMD的主要病原体,多见于气候温暖的季节;3岁以下的男性散居儿童是HFMD的高发人群;有必要进一步研究CVA6亚型HFMD的临床特征、流行特征和影响因素。

Abstract：Disease （HFMD） sentinel surveillance in Guangming New District of Shenzhen City in 2013, understand their epidemiologieal features, and provide references for HFMD prevention and control. [ Methods ] Descriptive research method was used to describe the epidemiological characteristics of 231 etiological positive cases from the HFMD sentinel surveillance in Guangming New District of Shenzhen City in 2013. [Results] The Enterovirus CVA6 infection contributed the most HFMD cases （69.70%） this district in 2013. The detection of Enterovirus CVA6 began to increase from April, and reached the peak in September, then gradually reduced. The positive detection of Eterovirus in 〈3 years age groups were the most in all age groups （96.97%）, and there was no significance （P 〉 0.05） among all age groups of the Enterovirus constitute differences. The sex ratio was 2.61：1, the pathogen positive rate was significantly different between genders （P 〈 0.05）, but their etiological constitution was not significantly different （P 〉 0.05）.The scattered children contributed the most （80.95%） of the etiological positive cases, the pathogen positive rate between different professions had significance （P 〈 0.05）, as well as the etiological constitution （P〈0.05）. [ Conclusion ] Enerovirus CVA6 is the major pathogens of HFMD in this district in 2013, and it mostly emerges in warm seasons. The male scattered children 〈3 years old were the high-risk group of HFMD. It is necessary to study the clinical features, epidemic characteristics and the influencing factors of HFMD caused by Enterovirus CVA6.
