How does a person get Legionnaires disease?
A. Legionnaires’ disease is contracted by inhaling airborne water droplets containing legionellae. Some investigators believe that the disease may be acquired also by drinking legionellae-contaminated water, particularly if legionellae aspirated from the water are inhaled before the water enters the stomach. Cases have also been blamed on contact between contaminated water and incisions or skin wounds.The disease is not contagious.
