Legionella Myth vs. Fact

Outbreaks of Legionnaires’ disease are typically associated with contaminated large or complex water systems, like those found in hospitals, hotels, long-term care facilities, and even gyms. The most likely sources of infection include, but are not limited to, showers, cooling towers, decorative fountains, and hot tubs.

Legionella is transmitted through the inhalation or aspiration (water accidentally enters the lungs) of small water droplets containing the bacteria. The contaminated droplets can take the form of a mist or spray. During infection, the bacteria will invade lung cells and replicate intracellularly.

The people most at risk for contracting Legionnaires’ disease are those with weakened immune systems. People with diseases such as HIV/AIDS, cancer, or diabetes; those who are over the age of 65; and those who have recently undergone an organ transplant have a greater risk of infection. Also, those whose lungs are weakened due to smoking or chronic emphysema are at risk of infection after exposure to the bacterium.
