Cooling towers in the community are the likely source of the Legionella bacteria causing this cluster of Legionnaires’ disease. Cooling towers are typically found on top of buildings. They control the temperature of cooling systems, such as refrigeration. The cooling towers spray mist that can contain the bacteria into the outside air.
