2009年中国细菌性痢疾监测分析

Surveillance of bacillary dysentery in China,2009

目的利用"中国疾病预防控制信息系统"及细菌性痢疾(菌痢)国家级监测点上报的监测数据,分析中国菌痢流行特征及监测中存在的问题。方法采用描述流行病学方法对2009年中国细菌性痢疾病例进行分析。结果中国菌痢的发病死亡呈下降趋势,发病以散居儿童和农民为主,发病高峰为6-8月;全国20个监测点采集的7764份样本志贺菌总的阳性检出率为8.73%(678/7764),病原菌型监测显示,福氏志贺菌和宋内志贺菌分别占67.26%(456/678)和32.74%(222/678),志贺菌株的耐药情况较为普遍,菌株对三代头孢菌素、庆大霉素和环丙沙星等药物敏感。结论 "中国疾病预防控制信息系统"和国家级菌痢监测点的主动监测可相互补充,对指导全国菌痢防控有积极意义。

Objective To analyze the epidemic pattern of bacillary dysentery and the problems in surveillance in China by using the surveillance data obtained from national disease reporting information system.Methods Descriptive epidemiological analysis was conducted.Results The morbidity and mortality of bacillary dysentery declined in China in 2009.The cases were mainly children outside child care settings and farmers,and the incidence peak was during June-August.The overall detection rate of Shigella in 7764 samples collected in 20 surveillance sites in China was 8.73%%（678/7764）.The pathogen type surveillance indicated that S.flexneri accounted for 67.26%（456/678） and S.Sonnei accounted for 32.74%（222/678）.The drug-resistance of Shegella strains was common,but they were sensitive to third-generation cephalosporin,gentamicin and ciprofloxacin.Conclusion National disease reporting information system and active surveillance in national surveillance sites of bacillary dysentery can provide more accurate information about the disease situation,which could facilitate the prevention and control of bacillary dysentery.
