It includes both Legionnaire's Disease, a severe form of pneumonia, and Pontiac Fever, a flu-like illness that is usually self limiting. Legionella is a naturally occurring bacteria commonly found in warm water sources such as large plumbing systems, hot water tanks, cooling towers, hot tubs, respiratory equipment, and decorative fountains.
