Legionellosis can present as two types of illness: Legionnaires’ (LEE-juh-nares) disease and Pontiac fever. The two illnesses can be diagnosed with similar tests, but are treated differently.
Legionnaires’ disease is a serious type of pneumonia (lung infection) frequently requiring hospitalization, whereas Pontiac fever is a less serious illness that is self-limiting and does not require treatment. People can get sick with Legionnaire's disease or Pontiac fever when they breathe in mist or accidently swallow water into the lungs containing Legionella (LEE-juh-nell-a) bacteria.
Legionnaire's Disease And Water Management Resources
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.
The training includes templates and other resources.
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
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.
