目的:了解光明新区妇幼保健院辖区5岁以下儿童腹泻病原学流行特征,为预防婴幼儿腹泻提供参考。方法:分析2011年9月~2013年8月光明新区内感染性腹泻病例,通过分离、培养、鉴定致病菌分析病原菌发病因素。结果:本辖区共有1435例婴幼儿病原性腹泻发生,其中病毒性腹泻1 136例,细菌性腹泻299例。病毒性腹泻以轮状病毒(RV)为主,占78.6%,5~12月为发病高峰阶段;细菌性腹泻以大肠埃希菌属为主,占20.8%,在5~11月为感染高峰时间段,峰值在5月。婴幼儿腹泻报告病例多数为散居和流动人口,男性比例远高于女性。结论:轮状病毒和大肠埃希菌属感染类腹泻是本辖区主要病原菌,散居儿童和流动人口婴幼儿是腹泻感染的高危人群。

Methods: The cases of infectious diarrhea in Guangming New District from September 2011 to August 2013 were analyzed. The pathogens were analyzed by isolating, culturing and identifying pathogens. Results: A total of 1435 cases of infant and pathogenic diarrhea occurred in this area, including 1,136 cases of viral diarrhea and 299 cases of bacterial diarrhea. Viral diarrhea was predominant in rotavirus (RV), accounting for 78.6% of the total, with a peak incidence from May to December. Bacterial diarrhea was mainly caused by Escherichia coli, accounting for 20.8%, peaked from May to November Time period, the peak in May.
