Legionnaires' disease is contracted by breathing in large numbers of the legionella Pneumophila bacteria. These bacteria are widespread in the environment and are able to thrive in warm water conditions. They can be found in water systems, such as hot water tanks, cooling towers and large air conditioning systems. They are more likely to be found in complex plumbing systems.
