How do you get Legionnaires' disease?
Legionella bacteria are found naturally in the environment and thrive in warm water and warm damp places. They are commonly found in bodies of water, soil and potting mix.
People usually get Legionnaires' disease by breathing in Legionella bacteria in very fine droplets of water called aerosols.
Man-made water systems sometimes provide environments that let Legionella bacteria increase to large numbers. These man-made systems include showers, spa pools, fountains, and also cooling towers associated with air conditioning and industrial cooling processes.
The evaporative units sometimes used in home air conditioning units have not been known to cause Legionnaires' disease. You cannot catch Legionnaires' disease from another person, or from drinking water contaminated by Legionella bacteria.
