目的掌握其他感染性腹泻病发病及肠道病原流行特征。方法收集2011年1月至2014年12月浙江省其他感染性腹泻病的发病数据及有病原学报告的个案资料,以X11方法进行发病及病原数据的季节因子提取,并进行发病与病原的季节因子的关联分析。结果浙江省其他感染性腹泻病存在夏季和冬季两个发病高峰,≤3岁组幼儿发病占所有病例比例约为50%;≤4岁组幼儿的发病高峰位于冬季,≥15岁组人群发病高峰在夏季,其余人群发病高峰不明显;报告的病原主要为轮状病毒(94.82%),其中轮状病毒和诺如病毒的发病高峰在冬季,其他病原的高峰出现在夏秋季;≤7岁组儿童发病季节模式与轮状病毒季节模式一致,≥9岁组人群发病模式与细菌类病原季节模式一致。结论≤3岁组儿童是主要发病人群,不同年龄段人群感染病原谱及发病季节模式不同,应根据其不同特征分类进行防制。
Objective To understand the incidence of other infectious diarrhea and enteric pathogens epidemiology. Methods From January 2011 to December 2014, the incidence data of other infectious diarrheal diseases in Zhejiang Province and the case data of etiological reports were collected. The seasonal factors of pathogenesis and pathogenic data were extracted by X11 method and the pathogenesis and pathogen season Correlation analysis of factors. Results There were two peak incidences of other infectious diarrheal diseases in Zhejiang Province in summer and winter. The incidence of young children ≤3 years old accounted for about 50% of all cases; the incidence peak of young children ≤4 years old was in winter, and the peak was 15 years old In the summer, the peak incidence was not obvious in the rest of the population. The main pathogens reported were rotavirus (94.82%). The rotavirus and Norovirus peaked in winter and the other pathogens peaked in summer and autumn. The season pattern of child onset is consistent with the rotavirus season pattern, and the pattern of disease in the group of ≥9 years is consistent with the seasonal pattern of bacterial pathogens. Conclusion Children less than 3 years old are the main disease groups. The pathogens of different stages of infection and the season of onset are different, and should be controlled according to their different characteristics.
