Legionnaires' Disease

Alternate Names : Legionella Pneumophila Pneumonia

Legionnaires' Disease | Symptoms & Signs | Diagnosis & Tests | Prevention & Expectations | Treatment & Monitoring

What can be done to prevent the infection?

Complete sterilization of the bacteria from water supplies is not practical. When a contaminated water source is identified, it may be treated. Following are some of the methods used to reduce levels of Legionella pneumophila in water supplies:

  • exposure to ultraviolet light
  • flushing
  • super heating
  • People with compromised immune systems are at high risk for Legionnaires' disease. Facilities that care for these people should monitor water supplies for the bacteria. Vaccinations are being developed for use in high risk individuals.

    What are the long-term effects of the infection?

    As many as 5% to 30% of the people with Legionnaires' disease die from the infection. Long-term effects include lung scarring and abscesses, or pus pockets. These effects are usually not severe.

    What are the risks to others?

    Legionnaires' disease is not communicable from one person to another. It is passed only by exposure to contaminated water.
