In a hospital's domestic water system, what should be done if Legionella is found in water dispensers?

Installing a filter on the dispensers is an effective approach to managing the presence of Legionella in water dispensers within a hospital's domestic water system. Filters can significantly reduce microbial contamination, including Legionella, by physically removing bacteria from the water before it is dispensed. This method can help ensure that the water provided to patients and staff is safe for consumption, thereby minimizing the risk of Legionnaires' disease.

In the context of water quality management in healthcare facilities, proactive measures such as installing filters are essential for protecting vulnerable populations, such as patients who may have compromised immune systems. This strategy is a part of a broader management plan that should include regular monitoring, maintenance of the water system, and other preventive actions to ensure safe water quality throughout the facility.

Addressing Legionella through filtration reflects best practices in infection control in healthcare settings, making the system safer for use without the drastic measures that other options may entail.
