目的了解广西细菌性痢疾(菌痢)暴发疫情的流行特征,评价预防控制效果,为今后的预防控制提供依据。方法收集、整理2006-2007年广西菌痢暴发疫情的资料,采用描述性流行病学方法分析疫情的流行病学特征。结果2006-2007年广西共暴发菌痢疫情9起,集中在农村村屯和乡镇学校,其中学校5起;暴发时间为3-12月,无明显季节性;病例症状以发热、腹痛和腹泻为主;病原以福氏志贺菌为主(主要为2 a型),其次为宋内志贺菌;传播途径仍以经水传播为主。结论广西菌痢暴发疫情仍处于较高的散发水平,农村和学校是菌痢暴发的高危地区;今后需加大农村地区改水、改厕及卫生防病知识宣传力度,采取综合措施进一步控制菌痢暴发疫情的发生。
Objective To understand the epidemiological characteristics of outbreaks of bacillary dysentery (bacillary dysentery) in Guangxi and to evaluate the effect of prevention and control so as to provide the basis for prevention and control in the future. Methods The data of outbreaks of bacillary dysentery in Guangxi during 2006-2007 were collected and analyzed, and the epidemiological characteristics of the epidemic were analyzed by descriptive epidemiology. Results Nine outbreaks of bacillary dysentery occurred in Guangxi from 2006 to 2007 were concentrated in rural village and township schools, of which 5 were in school. The outbreak time ranged from March to December with no obvious seasonal. The symptoms of the cases were fever, abdominal pain and diarrhea The main pathogen is mainly Shigella flexneri (mainly 2 a type), followed by Shigella sonnei; transmission is still based on water-based transmission. Conclusions The outbreak of bacillary dysentery in Guangxi is still at a high level. Rural and school schools are the high risk areas for bacillary dysentery outbreaks. In the future, efforts should be made to increase publicity on water diversion, lavatories and health and disease prevention in rural areas, and comprehensive measures should be taken to control bacteria Outbreak of dysentery occurred.
