摘要
目的了解南昌市2010—2013年手足口病聚集性疫情流行特征,为制定相应的防控措施提供科学依据。方法收集2010—2013年南昌市手足口病聚集性疫情信息,应用描述性流行病学方法进行数据处理。结果 2010—2013年南昌市共报告聚集性疫情195起,累计报告病例586例。聚集性疫情数和病例数均集中在城区;3—6月为聚集性疫情发生高峰期,9月为小高峰;疫情发生场所以幼托机构为主(68.2%);手足口病聚集性疫情2010—2013年在地区和场所间分布差异有统计学意义(χ2值分别为9.085,20.636,P值均<0.05)。采集病例标本367份,阳性率为59.13%(217/367),阳性标本中以肠道病毒71型(EV71型)为主(54.38%)。2010年以柯萨奇病毒A16型(Cox A16型)和其他肠道病毒为主,2011—2013年以EV71型肠道病毒为主。结论应继续加强城区、幼托机构手足口病发病监测,及时发现聚集性疫情,同时加强手足口病病原监测工作,了解病原变异情况。
Objective To explore the epidemic characteristics for clustering epidemic of hand foot and mouth disease （HFMD） in Nanehang, 2010-2013, and to provide scientific evidence for making the prevention measurements. Methods The data of clustering epidemic information of HFMD was collected timely in Nanchang City, 2010-2013, and analyzed by descriptive and analysis epidemiological methods. Results A total of 195 clustering epidemics and 586 cases were reported in Nanchang, 2010 -2013. Most of the Epidemics and cases were concentrated in urban areas （ which accounted for 70.26% and 70.99% respectively ）. The peak of clustering epidemic was in March-June, and another minor peak was in September. And the epidemic was mainly in the preschools （68.21%）. Significant differences were showed in different districts （χ^2 = 9.085, P = 0.028） and different areas （χ^2 = 20.636,P= 0.000）. A total of 367 samples were obtained,the positive rate was 59.13%（ 217/367）, and the intestinal virus EV71 type was the dominated of the positive sample（54.38%）. The leading type of the HFMD viruses was varied during two years at least. The type CoxA16 and the other intestinal viruses were the prior types. The type EV71 was the dominant type in 2011-2013. Conclusion The surveillance of HFMD should be strengthened in the urban areas or in the preschools persistently, and find the clustering epidemic timely. Meanwhile, the pathogen detection to acquaint the variation of virus should be strengthened.
