About the author:

Dr. Janet E. Stout

Dr. Janet E. Stout is internationally recognized for pioneering discoveries and research and in Legionella detection, control and prevention. An infectious disease microbiologist for more than 30 years, her expertise includes disinfection and control strategies for the prevention of Legionnaires’ disease and other waterborne pathogens. Her seminal discovery that demonstrated the link between the presence of Legionella in hospital water systems and Legionnaires’ disease shifted the paradigm from cooling towers to water distributions systems as the primary source for Legionnaires’ disease. Published in the New England Journal of Medicine in 1982, Dr. Stout’s findings changed the direction of research and expanded the water treatment industry’s approach to controlling Legionella. To date, Dr. Stout has evaluated every major Legionella disinfection technology used in the industry. Her work is published widely in major medical and scientific peer-reviewed journals.
