Legionella pneumophila is associated with pneumonia outbreaks linked to

Legionella pneumophila grows in warm, stagnant water found in man-made systems, and people become infected when they inhale tiny aerosol droplets containing the bacteria. Because aerosols are released by water-based systems, outbreaks are most commonly linked to sources like water supplies, humidifiers, and air-conditioning equipment (cooling towers and associated plumbing). It isn’t spread by food or soil, and transmission is not typically person-to-person. Hospitals can be places where outbreaks originate due to complex water systems, but the underlying connection is the water-based aerosol source. This is why the best answer points to water-related sources such as water supplies, humidifiers, and air conditioning equipment.
