目的分析2014年南阳市手足口病的流行特征,为制定防控措施提供依据。方法资料来自《传染病报告信息管理系统》,采用描述流行病学方法进行统计分析。结果南阳市2014年报告手足口病9946例,其中重症878例,死亡5例,年发病率为114.61/10万,病死率为0.05%。发病高峰为4月;各地区均有发病,地区间发病水平差异明显;男性发病高于女性;以5岁以下的散居儿童为主。病原学监测结果肠道病毒71型(EV71)所占比例为57.44%,柯萨奇病毒A16型(CoxA16)所占比例为13.10%,其他肠道病毒(PE)所占比例为29.46%。重症病例的EV71分布与普通病例的EV71分布差异有统计学意义。结论 2014年南阳市手足口病疫情处于较高发病水平,5岁及以下儿童是发病主要人群,EV71为主要病原,应进一步加强手足口病防控工作。
Objective To analyze the epidemiological characteristics of hand-foot-mouth disease in Nanyang in 2014 and provide the basis for the development of prevention and control measures. Method information from “Infectious Disease Reporting Information Management System” describes the use of epidemiological methods for statistical analysis. Results Nanyang reported 9,946 HFMD cases in 2014, of which 878 were severe and 5 were fatal, with an annual incidence of 114.61 / 100,000 and a case fatality rate of 0.05%. The peak incidence was in April; all regions had morbidity, the incidence of inter-regional differences was significant; the incidence of males was higher than that of females; and the majority were diasporas below 5 years old. The results of pathogen detection showed that enterovirus 71 (EV71) accounted for 57.44%, CoxA16 accounted for 13.10% and other enteroviruses (PE) accounted for 29.46%. EV71 distribution of severe cases and common cases of EV71 distribution difference was statistically significant. Conclusion In 2014, the epidemic situation of HFMD in Nanyang City was at a relatively high incidence. Children aged 5 and below were the main pathogens and EV71 was the major pathogen. Prevention and control of hand, foot and mouth disease should be further strengthened.
