摘要
目的明确2017年5月云南一起腹泻暴发疫情的病原及感染来源,为制定预防控制措施提供依据。方法采用现场流行病学调查方法对云南省绿春县戈奎乡俄马村委会新寨村发生的一起腹泻疫情进行流行病学调查,现场采样、实验室检测以及数据资料统计分析。结果本次暴发病例44例,采集的13份标本中11份A组轮状病毒核酸阳性,阳性率84.62%。调查显示供水管破损且被人畜粪便及生活污水污染,破损水管走向与病例分布基本一致,且降雨量与发病数呈显著相关。结论本次事件是一起由A组轮状病毒引起的腹泻暴发疫情,降雨导致饮用水直接污染可能是本次暴发的危险因素,应加强对农村饮用水的卫生管理和对村民进行预防肠道传染病健康知识宣传教育。
