目的掌握2009—2013年克拉玛依市手足口病流行特征,为防控提供科学依据。方法以描述流行病学方法分析2009—2013年克拉玛依市手足口病疫情。结果 2009—2013年克拉玛依市分别报告手足口病病例243例、319例、226例、437例和188例,发病率分别为81.34/10万、106.71/10万、58.06/10万、111.33/10万和48.09/10万;发病高峰在每年的5—8月,6月达全年最高峰,2013年呈现3个发病高峰;各年龄组发病数男性均高于女性,3岁左右幼托儿童和散居儿童是手足口病最主要的发病群体;不同年份EV71(χ2=36.97)、CA16(χ2=51.85)病原阳性率差异有统计学意义(均P<0.01),2011年和2013年,手足口病病原以EV71为主,2010年和2012年以CA16为主。结论 2010年和2012年较其他年份手足口病报告病例数、发病率均有所上升,2010—2013年流行优势毒株发生转变;3岁左右幼托儿童和散居儿童是手足口病防控重点人群,应加强防病宣传。
Objective To grasp the epidemiological characteristics of hand-foot-mouth disease in Karamay from 2009 to 2013 and provide a scientific basis for prevention and control. Methods Epidemiological methods were used to analyze HFMD epidemics in Karamay from 2009 to 2013. Results From 2009 to 2013, Karamay City reported 243 cases of hand-foot-mouth disease, 319 cases, 226 cases, 437 cases and 188 cases respectively. The incidence rates were 81.34 / 100000, 106.71 / 100000, 58.06 / 100000, 111.33 / 10 Million and 48.09 / 100000; the peak incidence in the annual 5 - August, June reached the peak throughout the year, 2013 peaked at 3; incidence of each age group were higher than the number of males, 3-year-old child care child care And scattered children were the most important pathogens of HFMD. The positive rates of EV71 (χ2 = 36.97) and CA16 (χ2 = 51.85) in different years were significantly different (all P <0.01). In 2011 and 2013, Stomatopathy to EV71-based, in 2010 and 2012 to CA16-based. Conclusion The reported cases and incidence rates of HFMD in 2010 and 2012 are higher than those reported in other years, and the prevalence of prevalent strains is changing from 2010 to 2013. Pre-triad and diaspore children are the key prevention and control of hand-foot-mouth disease Crowd, disease prevention and publicity should be strengthened.
