Legionella Guidelines

In the absence of a cohesive national approach to prevention, professional organizations have produced their own standards and creating new ones due to the increased cases of Legionnaires' disease. SPL developed the first U.S. guideline in 1993 that continues to serve as a national and international model for prevention.
