【摘要】：目的分析学校发生的一起细菌性痢疾暴发疫情状况,并采用脉冲凝胶电泳(PFGE)方法对致病菌株进行同源性分析,为今后此类疫情的防控提供经验。方法开展现场流行病学调查,采用描述和分析流行病学的方法对暴发原因进行分析,同时开展病原学检测,运用PFGE对分离的菌株进行同源性分析。结果此次疫情波及2所学校,即A中学和B小学。共发现病例358例(疑似病例291例,确诊病例67例),其中A中学233例,罹患率为4.82%;B小学125例,罹患率为2.88%,均为学生。从37例患者的粪便中共检出20株宋内志贺菌;对23株宋内志贺菌进行PFGE分析,发现A中学和B小学的菌株分型为同一带型。饮用直饮水生水是该次疫情发生的主要危险因素(OR=2.04,95%CI=1.18~3.53),但不排除与相似症状病人接触和不洁的生活习惯是可能危险因素。结论在学校开学之际落实各项菌痢防控措施,提高学校卫生工作质量非常重要。
[Abstract]:Objective to analyze the school of an outbreak of bacillary dysentery, and using pulsed field gel electrophoresis (PFGE) method to analyze the homology of pathogenic strains, provide experience for the future of such disease control. Epidemiological investigation of the scene to carry out the method, using the method of epidemiological description and Analysis on outbreak reason analysis, and carry out the pathogen detection, the use of PFGE on the isolated strains for homology analysis. Results the epidemic spread to 2 schools, namely A and B were found in middle school primary school. In 358 cases (291 suspected cases, 67 cases of confirmed cases), including 233 cases of A middle school, the attack rate was 4.82%; 125 cases of B primary school, the attack rate was 2.88%. Are students. 20 strains of Shigella sonnei were detected from 37 cases of patients with fecal CCP; PFGE analysis of 23 strains of Shigella sonnei, found A middle school and primary school B strain typing for the same area. Drinking unboiled water is the The main risk factors of the outbreak (OR=2.04,95%CI=1.18~3.53), but not to the exclusion of similar symptoms and patient contact and unclean habits are risk factors. Conclusion the implementation of the measures for the prevention and control of bacillary dysentery in school are very important to improve the quality of school health work.
