2. How does Legionnaires’ disease spread?
Legionella bacteria are generally spread through airborne water droplets. Mist or vapor contaminated with the bacteria will come from whirlpool spas, cooling towers (used as air-conditioning units in large buildings), and water used for bathing and drinking, based on the CDC.
The condition can happen any moment of year but is most common through the summer and early fall.
Window and automobile air conditioners do not appear to allow the bacteria to grow, and the bacteria aren’t spread from individual to individual, based on the CDC.
