Legionellosis is a severe bacterial infection, most commonly presenting as pneumonia (Legionnaires' Disease), caused by *Legionella* bacteria. It is not contagious person-to-person and primarily affects individuals who inhale contaminated water droplets, especially older adults or those with weakened immune systems.

Legionellosis first gained widespread recognition following a major outbreak in 1976 at an American Legion convention in Philadelphia, Pennsylvania. The causative bacterium, *Legionella pneumophila*, was identified by the CDC shortly after. This event significantly advanced public health understanding of waterborne diseases and the importance of environmental controls in buildings.
Legionellosis is primarily transmitted through the inhalation of small water droplets (aerosols) containing *Legionella* bacteria. These contaminated aerosols are generated from man-made water systems such as cooling towers, hot tubs, showers, decorative fountains, and large plumbing systems. It is not known to spread directly from person to person.
