After receiving notice of increased Legionella in the NICU, what action should the IP take next?

• A. Initiate isolation procedures in the NICU
• B. Notify hospital administration about Legionella
• C. Discuss appropriate next steps with the person in charge of water testing
• D. Collect water samples from the NICU

Answer: (C)

When Legionella is reported as increased in a NICU, the next step is to collaborate with the person responsible for water testing to chart the plan. This individual understands the current sampling framework, where to collect specimens, what tests to run, and how quickly results are expected. By discussing next steps, the IP ensures testing is systematic, sources are identified, and appropriate environmental controls are put in place before considering broader actions. Legionella spreads through inhalation of aerosols from contaminated water, not from person-to-person contact, so the focus is on reducing exposure with targeted environmental interventions rather than immediate patient isolation. Administrative notifications are important, but they should follow a plan grounded in the water testing lead’s guidance. Collecting samples without a coordinated plan can miss sources or waste time, whereas a coordinated discussion sets the course for effective remediation.
