About the Disease
Legionnaires' disease is a severe, often lethal, form of pneumonia. It's caused by the bacterium Legionella pneumophila found in both potable and nonpotable water systems. Each year, an estimated 10,000 to 18,000 people are infected with the Legionella bacteria in the United States.
It is not uncommon for patients with Legionnaires' disease to be admitted to the intensive care unit. Some will suffer long-term impaired health-related quality of life. A study of outbreak survivors showed persistence of fatigue (75%), neurologic symptoms (66%) and neuromuscular symptoms (63%) in months after an outbreak.

Guideline from New York Department of Health
This document from the New York Department of Health was prompted by inflammatory media coverage of outbreaks of Legionnaires' disease in New York hospitals. It documents the importance of routine environmental surveillance for Legionella as a preventive measure for hospital-acquired Legionnaires' disease.

Legionnaires' Disease - Denis Green
This is a colorful website manned by Denis Green, a layperson. As such, it contains some information that has not been scientifically validated, but reflects the personal biases of the creator. For healthcare professionals, the site does contain a listing of Legionella outbreaks publicized in the lay media. For laypersons, it contains information about support groups for those who contract LD.
