Legionella & Legionnaires’ Disease (Legionellosis)
Legionella is a naturally occurring waterborne bacteria that can be found in building water systems such as water storage containers or pipes. Exposure normally occurs when contaminated water is aerosolized and inhaled into the lungs.
This collection provides information on the risks posed by legionella to water systems and the preventative management, standards and sampling/testing of the bacteria in building water systems. Health information and outbreak case studies for Legionnaire’s Disease (Legionellosis) and Pontiac Fever are included.
