摘要
目的 :查明感染性腹泻病因、传播途径以及有关影响因素 ,完善有效控制该病流行的策略。方法 :用样本估计总体发病水平推断流行强度。流行因素采用病例对照调查 ,并进行危险因素的单因素分析和多因素 logistic回归分析 ;病原学检测使用普通培养基以及免疫磁株法与珂玛嘉、彩虹、头孢可肟三种特选培养基联合应用。结果 :流行区感染性腹泻罹患率 3.6 9% ,并出现多例伴急性肾功能衰竭。优势菌为志贺氏菌属 ,占检出病原菌总数的 6 5 .6 7% (88/134) ,大肠杆菌为流行过程的次优势菌株 ,检出 34株 ,占 2 5 .37% ,出血性大肠杆菌 (EHEC) O15 7:H7是重症病例重要病原。吃剩饭菜、无防蝇设备和饭前洗手 3项因素对腹泻病发生和流行有意义。结论 :应通过卫生宣教、外环境灭蝇灭蛆及合理治疗腹泻病人控制疫情。
Objective: To find out etiological factors of the infectious diarrhea, the route of transmission and the relation of influenced factors. Methods: Samples was adopted to estimate total disease incidental level and epidemic strength. Case-control study was adopted to investigate the epidemic factors. Both single and multiple factors logistic regression analysis were conclucted to analyze the risk factor. It was carried out in etiology detection that the ordinary medium and the unite application of the immuno-gold kits and three particular medium. Results: A total of 294 636 cases were attacked in epidemic area including several cases with acute renal insufficiency. Shigella was the superiority germ and it covered 65.67% (88/134) in all checking out pathogens. Escherichia coli was the under-superiority germ in epidemic process. 34 germs were checked out. The rate of checking out was 25.37%. Enterohemorrhagic E.coli (EHEC)O157:H7 was the important pathogen in critical cases. Three factors were significant for the occurring and epidemic of diarrhea, such as people ate remained meal, no masks for prevent flies and unwashed hangs before one eat. Conclusion: It is necessary for us to conduct health education so as to control the epidemic status.
