2008-2014年云南省保山市手足口病的流行与病原特征分析

Epidemiological and etiological characteristics of hand foot and mouth disease in Baoshan, Yunnan, 2008-2014

  • 摘要: 目的 了解云南省保山市手足口病流行与病原学特征,为疾病防控提供科学依据。方法 用描述性统计法和地理信息系统分析云南省保山市2008-2014年的手足口病患者资料;基于实时荧光定量聚合酶链反应对随机抽取的患者标本进行毒株筛选和评估。结果 2008-2014年保山市通过网络直报的手足口病患者总计为15025例,其中重症98例,死亡5例,发病率从2008年的12.5/10万升至2014年的147.2/10万。病例的区域分布提示以隆阳区的病例构成及发病率最高(47.4%,110/10万);病例流行有明显的季节性特征,峰值出现在夏季前后(4-7月、9-12月),冬春少见;病例大多是5岁以下的儿童(93.9%),相对集中在1岁年龄组(2192.8/10万),儿童病例中以分散居住(85.0%)明显多于托幼机构(10.2%)。抽取1042例病例标本经检测阳性为680例(65.3%):柯萨奇病毒A组16型247例、肠道病毒71型173例、其他肠道病毒189例、混合感染71例。结论 手足口病在云南省保山市的发病率呈逐年上升趋势,在发病的季节、年龄、区域分布和优势毒株型均有较典型的流行特征。提示对重点地区的重点人群亟需加强健康宣教和干预措施。

     

    Abstract: Objective To identify the epidemiological and etiological characteristics of hand foot and mouth disease (HFMD) in Baoshan, Yunnan province, and provide scientific evidence for the prevention and control of HFMD. Methods Descriptive statistical study and geographic information system were used for analyzing the surveillance data of HFMD in Baoshan from 2008 to 2014, and real-time RT-PCR was used for testing etiological samples of HFMD. Results A total of 15025 HFMD cases were reported in Baoshan during this period, including 98 severe cases and 5 deaths. The incidence of HFMD increased from 12.5/lakh in 2008 to 147.2/lakh in 2014. Most cases (47.4%) were reported in Longyang district, where the incidence was highest (110/lakh). Overall, the annual incidence peaked during April-July firstly, then during September-December. Most cases (93.9%) were less than 5 years old, and the incidence was highest in age group 1 year (2192.8/lakh). About 85% of the cases were detected outside child care settings, and 10.2% of the cases were detected in child care settings. Etiological test of 1042 samples showed that 680 were positive (65.3%), in which 247 were positive for CoxA16, 173 were positive for EV71, 189 were positive for other enteroviruses and 71 were positive for multi viruses. Conclusion The incidence of HFMD showed an upward trend from 2008 to 2014, but the age, area and seasonal distributions varied, and the predominant pathogen varied with year. Effective measures should be taken to strengthen the prevention and control of HFMD among risk populations in community and childcare setting.
