摘要
目的 分析2010—2020年中国大陆食源性致泻大肠埃希氏菌暴发事件的季节特征,为减少食源性暴发事件的发生及针对性地开展防治措施提供科学依据。方法 收集整理2010—2020年国家食源性疾病暴发监测系统中调查确定致病因子为致泻大肠埃希氏菌的食源性疾病暴发事件监测资料,采用圆形分布法分析食源性致泻大肠埃希氏菌暴发事件的季节特征和月份分布规律。结果 2010—2020年中国大陆累计报告食源性致泻大肠埃希氏菌暴发事件349起,暴发事件发生高峰期为5~9月(74.50%,260/349),事件分布存在季节聚集性,平均发病高峰时点为7月10日,平均流行高峰期为4月24日至9月25日。结论 中国大陆食源性致泻大肠埃希氏菌暴发事件存在明显季节性趋势,发病高峰期在夏秋季节,需在发病高峰期来临前提早采取有效防控措施。
Objective To provide scientific basis for preventing foodborne outbreaks and carrying out targeted prevention and control measures,the seasonal characteristics of foodborne diarrheagenic Escherichia coli outbreaks in China’s Mainland from 2010 to 2020 was analyzed.Methods Circular distribution method was used to analyze the data about diarrheagenic Escherichia coli outbreaks which was collected by Foodborne Disease Outbreaks Surveillance System from 2010 to 2020.Results From 2010 to 2020,a total of 349 foodborne diarrheagenic Escherichia coli outbreaks were reported in China’s Mainland. Generally,the peak of Escherichia coli outbreaks was from May to September(74. 50%,260/349),and there was a significant centralized trend in event distribution,with the peak day on July 10. The epidemic peak period was from April 24 to September 25.Conclusion There is an obvious seasonal trend in foodborne diarrheagenic Escherichia coli outbreaks in China’s Mainland,and the peak period is in summer and autumn. Effective prevention and control measures should be taken in time before the peak period.
