Water as a source for colonization and infection with multidrug-resistant pathogens: Focus on sinks

Water distribution systems have long been known to be reservoirs and occasional sources for healthcare-associated infections (HAIs). Recently, hospital-building wastewater systems including sinks and drains have received more attention as potential sources of transmission of multidrug-resistant gramnegative bacilli. In this issue of Infection Control and Hospital Epidemiology, studies by Dr Curtis Donskey’s research group add to our understanding of the importance of sink drains as reservoirs of pathogens and describe potential interventions to reduce contamination of surfaces surrounding sinks. This commentary focuses on the growing body of evidence linking sinks to HAIs and discusses strategies to mitigate the risk of transmission of pathogens from sinks to patients.
