For many years, patient-area wastewater drains (ie, sink and shower drains) have been considered a potential source of bacterial pathogens that can be transmitted to patients. Recently, evolving genomic epidemiology tools combined with new insights into the ecology of wastewater drain (WWD) biofilm have provided new perspectives on the clinical relevance and hospital-associated infection (HAI) transmission risks related to these fixtures. To further clarify the clinical relevance of WWD-associated pathogen transmission, reports of outbreaks attributed to WWDs were selected for review that (1) investigated the outbreak epidemiology of WWD-associated transmission of bacterial pathogens, (2) utilized advanced microbiologic methods to establish clonality of outbreak pathogens and/or resistance genes, or (3) described interventions implemented to mitigate transmission of the outbreak pathogens from WWDs. These reports were collated, compared, and analyzed, and the results are presented here.
多年来，患者区域污水排水系统（即水槽和淋浴排水系统）一直被认为是细菌病原体的潜在来源，这些病原体可能会传播给患者。最近，不断发展的基因组流行病学工具结合对污水排水系统（WWD）生物膜生态学的新认识，为这些装置与临床相关性和医院相关感染（HAI）传播风险提供了新的视角。为了进一步阐明与 WWD 相关的病原体传播的临床相关性，选择了与 WWD 相关的病原体传播暴发报告进行审查，这些报告（1）调查了与 WWD 相关的细菌病原体传播的暴发流行病学，（2）利用先进的微生物学方法确定了暴发病原体的克隆性和/或耐药基因，或（3）描述了为减轻 WWD 传播暴发病原体而实施的干预措施。对这些报告进行了整理、比较和分析，并在此呈现了结果。
