摘要
目的了解广州市其他感染性腹泻流行病学特征,为有效控制感染性腹泻提供依据。方法对广州市2005-2008年疾病监测信息报告系统中上报的其他感染性腹泻病例进行描述性流行病学分析。结果2005-2008年广州市共报告其他感染性腹泻病例55081例,年发病率介于108.83/10万～152.78/10万之间,呈逐年上升趋势。5岁以下年龄组占全部发病数的64.49%。10-12月为发病高峰。报告发病率居前5位的地区为南沙、黄埔、花都、越秀和番禺。实验室诊断病例中,8789例有明确病原体信息,占报告病例总数的16.0%,其中轮状病毒、腺病毒及两者合并感染分别占实验室诊断病例的75.49%、10.83%和13.49%。共报告其他感染性腹泻暴发疫情7起,6起由诺如病毒引起。结论广州市2005-2008年其他感染性腹泻流行主要集中于0～5岁散居儿童,秋冬季是其他感染性腹泻的好发季节,轮状病毒为主要病原体,且存在轮状病毒和腺病毒交叉感染。降低轮状病毒性腹泻发病率是有效控制感染性腹泻的重要措施之一。

Rotavirus, enteric adenovirus and combined infections accounted for 75.49% , 10. 83% and 13.49% of laboratory confirmed cases, respectively. Seven outbreaks of infectious diarrhea were reported, six of which were caused by norovirus. Conclusion The infectious diarrhea was clustered in 0 -5 years old children, and peaked in au- tumn and winter seasons. Rotavirus was the major pathogen.
