PreventLD Training - Preventing Legionnaires’ Disease Training | EHS | CDC



Preventing Legionnaires’ Disease: A Training on Legionella Water Management Programs (PreventLD Training)

Are you involved in water safety for buildings? Take this training from CDC and partners on creating a water management program to reduce risk for Legionnaires’ disease. PreventLD Training aligns with industry standards (ASHRAE 188) on managing risk for Legionella bacteria.

Get Started Today

  1. Visit the Western Region Public Health Training Center at the University of ArizonaExternalExternal and create an account (or log in if you already have one). You can also register through TRAIN.ExternalExternal
  2. Enroll in PreventLD Training.

What Are the Benefits of This Training?

PreventLD Training
  • Outlines how to reduce risk for Legionella in facilities through water management programs.
  • Helps water management programs align with ASHRAE 188 on reducing risk for Legionella in building water systems (e.g., potable water, cooling towers, hot tubs, decorative water features).
  • Is free and available online, and continuing education units are available from the National Environmental Health Association (NEHA).
  • Helps build common language across the range of professionals involved in water management programs.
  • Includes case studies, templates, and other practical resources to reduce the risk for Legionella and protect those at increased risk of Legionnaires’ disease: adults aged 50 years or older, current or former smokers, and those with a weakened immune system or chronic disease.

The Centers for Medicare & Medicaid Services (CMS) now requires healthcare facilities to have water management policies and procedures to reduce the risk of Legionella and other pathogens in building water systems.

Who Is This Training For?

CDC and partners designed this PreventLD Training for the range of professionals involved in water management programs. This typically includes
  • Public health professionals, including infection preventionists.
  • Building managers, maintenance/engineering staff, and safety officers.
  • Equipment and water treatment suppliers as well as consultants.
This training addresses how to manage
  • Building water systems in hospitals, retirement homes and long-term care facilities, hotels, high-rise apartment complexes, and other buildings.
  • Other devices that may need a water management program even if the building does not, such as cooling towers, decorative fountains and water features, hot tubs, and misters.

What Topics Does the Training Address?

The training addresses the 7 steps of a Legionella water management program. These 7 steps, outlined in CDC’s Water Management Program toolkit, operationalize the ASHRAE 188 standard for minimizing the risk of Legionnaires’ disease.

The training includes templates and other resources.
Module A: Getting Started – Introduction to Legionella
Step 1: Create a Water Management Program Team
Module B: Hazard Analysis
Step 2: Describe the Building Water Systems Using Text and Flow Diagrams
Step 3: Identify Areas Where Legionella Could Grow and Spread
Module C: Hazard Control
Step 4: Decide Where Control Measures Should Be Applied and How To Monitor Them
Step 5:  Establish Ways To Intervene When Control Limits Are Not Met
Module D: Confirmation
Step 6: Make Sure the Program Is Running as Designed and Is Effective (Verification and Validation)
Step 7:  Document and Communicate All the Activities of Your Water Management Program
The training also includes case studies in a healthcare facility and manufacturing facility as well as resources for creating water management program action plans.

What Are People Saying?

“…easy to follow for someone new to the field, and also provided enough detail for individuals already involved in Legionella prevention. The comprehensive training guided me from basic understanding of the disease, to development of a water management program. This training set the bar in educational material on the topic of Legionnaires’ disease.”
-Robert Cole, REHS, Southern Nevada Health District
“I think it’s excellent. It does a great job of explaining the biology and epidemiology of Legionella and its relationship with the built environment. It’s the most comprehensive approach to understanding, creating, and implementing a meaningful, personalized Water Management Program. In general, it takes the toolkit to a whole new level. We’ve had facilities ask how they can create a WMP, and this is the perfect resource. In Georgia, we’ve already shared PreventLD Training with our healthcare facility, tourist accommodation, and hot tub regulatory partners, and we’re planning to share it with others. THANK YOU for this resource!!!!”
Liz Hannapel, MPH, Legionella Surveillance Coordinator, Georgia Department of Public Health
“This course is great for individuals who advise or oversee any environmental health programs that deal with a building or water system.”
-TRAIN user
“I only had a cursory knowledge of Legionella before completing this course. This course has great information; I now feel like I have a better understanding of the disease and steps to reduce risk.”
-TRAIN user

How Long Does It Take?

Pilot testers took an average of a half hour to complete each module and an average of 3 hours to complete the training as a whole.
Users do not have to complete the training all at once. They can save their progress and come back later to complete a module.

Who Developed It?

The following groups developed this training:
  • CDC’s National Center for Environmental Health.
  • CDC’s National Center for Immunization and Respiratory Diseases.
  • The National Network of Public Health Institutes.
  • The University of Arizona Mel and Enid Zuckerman College of Public Health.
  • The Western Region Training Center at the University of Arizona.

Did You Know?

  • The number of people with Legionnaires’ disease grew 5.5 times from 2000–2017.1
  • In general, Legionnaires’ disease is deadly for about 10% of people who get it.2 It is deadly for about 25% of people who get it from a healthcare facility.3
  • CDC investigations show almost all (9 in 10) Legionnaires’ disease outbreaks were caused by problems preventable with more effective water management.4
  • An increasing number of people in the United States are getting this disease, which is caused by breathing in small water droplets containing Legionella.5
