目的了解平坝县细菌性痢疾(菌痢)发病特征和流行趋势,为制订菌痢的防治对策提供依据。方法对平坝县2004-2010年菌痢疫情及病原学监测资料作描述性分析。结果平坝县2004-2010年菌痢发病率波动在13.52/10万～72.80/万之间,年均发病率为36.03/10万。全年均可发生,以5-10月为发病高峰;各年龄组均可发病,0～5岁婴幼儿发病最多;职业发病顺位由高到低依次为农民、散居儿童、学生和幼托儿童。2008-2010年监测志贺菌总检出率4.35%,均为福氏志贺菌,6株志贺菌为多重耐药株。临床诊断符合率33.33%。结论平坝县菌痢发病率总体呈下降趋势,但仍处较高水平。流行菌型变迁,菌株耐药较严重,临床存在误诊、漏诊现象,需重视监测等防控工作。
Objective To understand the incidence and epidemic trend of bacterial dysentery (bacillary dysentery) in Pingba County and provide evidence for the prevention and control measures of bacillary dysentery. Methods Descriptive analysis of the epidemic situation of Shigella and monitoring data of etiology from 2004 to 2010 in Pingba County was conducted. Results The incidence of dysentery in Pingba County fluctuated from 13.52 / 100 000 to 72.80 / 000 between 2004 and 2010, with an average annual incidence of 36.03 / 100 000. Occurred throughout the year, the peak incidence in May-October; all age groups can be onset, 0 to 5-year-old infants the most; occupational disease from high to low in order of farmers, diasporas, students and child care child. The total detection rate of Shigella from 2008 to 2010 was 4.35%, all of which were Shigella flexneri and six Shigella strains were multi-drug resistant. Clinical diagnosis coincidence rate of 33.33%. Conclusion The incidence of bacillary dysentery in Pingba County is generally declining, but still at a high level. The prevalence of epidemiological changes, strains more serious drug resistance, clinical misdiagnosis, missed diagnosis, monitoring and other prevention and control should pay attention to work.
