目的分析引起这起疫情的主要原因,为今后控制感染性腹泻爆发流行提供科学依据。方法采用现场流行病学和实验室检验。结果此次疫情共报告病例279例,罹患率12.51%,病原学检测为肠致泻性大肠杆菌。主要症状为腹胀、腹痛、腹鸣、腹泻、多无发热。疫情发生原因为肠致泻性大肠杆菌污染了管网水所致。结论控制感染性腹泻等肠道传染病爆发疫情,及时发现疫情是前提,措施到位是保障,做到“早、小、严、实”是关键。
Objective To analyze the main causes of the outbreak and provide a scientific basis for controlling the outbreak of infectious diarrhea in the future. Methods Field epidemiology and laboratory tests were used. Results A total of 279 cases were reported in this epidemic, with an attack rate of 12.51%. The pathogenic test was intestinal diarrhea-causing Escherichia coli. The main symptoms are bloating, abdominal pain, abdominal flares, diarrhea, and more without fever. The cause of the outbreak is intestinal diarrhea caused by E. coli contaminated pipe network water. Conclusion It is the precondition to control the outbreak of intestinal infectious diseases such as infectious diarrhea in time and find out the outbreak in time. The measures are in place to ensure that “early, small, strict and real” is the key.
