摘要
目的 了解湖南省2009~2013年细菌性痢疾的流行病学特征和病原学特征,为制定防控策略提供科学依据。方法 采用描述性流行病学方法对湖南省卫生机构2009~2013年通过全国疾病监测系统报告的细菌性痢疾监测数据进行描述性分析。结果 2009~2013年湖南省共报告细菌性痢疾47 175例,年均发病率为14.47/10万,呈逐年下降趋势,发病具有明显的季节性,湘西和湘南地区是菌痢高发地区,发病以3岁以下幼儿为主,男性发病水平高于女性。暴发疫情主要发生在农村的中小学校,以水源性传播为主。2011~2013年湖南省疾控中心共收集176株菌痢菌株,其中宋内氏志贺菌109株,福氏志贺菌67株;湖南省志贺菌耐药较严重,不同群别志贺菌的耐药谱有所不同。结论 湖南省细菌性痢疾疫情分布存在比较明显的高发地区、高发时间和高发人群,应根据流行特征和病原学特征采取针对性的防控措施。
Objective To investigate the epidemiological features and pathogen characteristics of bacillary dysentery in Hunan province in 2009-2013, and to provide scientific basis for disease control and prevention. Methods Data of bacillary dysentery cases reported by health agencies in Hunan province through the National Disease Surveillance System from 2009 to 2013 was collected and analyzed descriptively. Results The 47 175 cases of bacillary dysentery were reported in Hunan province with the average annual incidence rate of 14.47/100 000. The incidence declined annually and obvious seasonality was found . The western and southern Hunan was the high prevalence areas. Most of the dysentery cases were children under 3 years old, and there was higher incidence in male than female. The outbreak occurred mainly in rural primary and secondary schools, waterborne transmission was the main route. 109 Shigella sonnei strains and 67 Shigella flexneri strains were detected in the laboratory; drug-resistant shigella was serious, and different serotypes of shigella had different drug resistance spectrum. Conclusion The distribution of bacillary dysentery showed obviously characteristics of regional epidemic, seasonal peak and high infection groups. Prevention and control measures should be taken based on epidemiological and etiology genetic characteristics.
