Clinical SME Oversight
This analysis was developed by Penny Pratt, RN, CSPI, providing Expert-in-the-Loop review to support clinical accuracy, patient safety, and responsible healthcare communication.
As Legionella continues to challenge healthcare and public health systems, effective prevention requires more than water system management. It requires clear clinical recognition and communication. For this MedReport Foundation article, I provided clinical oversight to clarify the spectrum of illness, from self-limiting Pontiac fever to life-threatening Legionnaires’ disease.
The result is an evidence-based resource designed to support healthcare and public health professionals in prevention planning, early recognition, and informed decision-making.
