目的了解龙岩市2008-2009年手足口病流行特征及病原学特点,为防控提供依据。方法用《疾病监测信息报告管理系统》的监测报告卡信息和实验室检测数据,用SPSS17.0软件包分析。结果 2008-2009年手足口病年均发病率为47.23/10万;病例地区分布以新罗区为主,占51.32%,报告发病率为119.29/10万;年龄以5岁以下为主;性别为男女1.74∶1;季节存在5~7月和9~12月两个高峰。病原学监测结果提示,2008-2009年7个县(市、区)均监测到EV71;2008年4月前所有阳性标本均为CoxA 16,2008年6月-2009年6月均为EV71,2009年7月以后则出现CoxA16和EV71并存现象,但CoxA16所占的比例呈上升趋势,EV71所占比例呈下降趋势。结论龙岩市手足口病发病有一定的地域集中性和季节性,以5岁以下儿童为主,流行病原存在CoxA16和EV71交替或共存现象,今后一段时期总体疫情将趋于温和,但EV71引起的局部暴发流行、出现重症或死亡病例的可能仍不能排除,提示仍需提高防范意识,对重点地区、重点人群采取有效的防控措施。
Objective To understand the epidemiological and etiological characteristics of HFMD in Longyan from 2008 to 2009 and provide the basis for prevention and control. Methods Monitoring report card information and laboratory test data of Disease Surveillance Information Report Management System were analyzed by SPSS17.0 software package. Results The annual incidence rate of hand-foot-mouth disease was 47.23 / 100 000 in 2008-2009.

The results of etiological monitoring suggested EV71 was detected in all 7 counties (cities and districts) from 2008 to 2009; all positive samples were CoxA 16 before April 2008, EV71 and 2009 from June 2008 to June 2009 After July, CoxA16 and EV71 co-exist, but the proportion of CoxA16 is on the rise and the proportion of EV71 is on a downward trend. Conclusion The prevalence of hand-foot-mouth disease in Longyan City is mainly regional and seasonal. The prevalence of CoxA16 and EV71 in the epidemic pathogen is alternating or coexisting. The general epidemic will tend to be milder in some period in the future, but EV71 The outbreak of local outbreak, the possibility of serious or death cases still can not be ruled out, suggesting that the need to raise awareness of prevention, key areas, key populations to take effective prevention and control measures.
