Legionnaires Disease is a severe lung infection caused by Legionella bacteria and can be fatal if not treated promptly.
Legionella is a naturally occurring bacterium and is present in bodies of water and soil.
Legionnaires Disease is not spread from person-to-person contact, nor is it airborne. People contract the disease by aspirating, or breathing in, water vapor infected with the bacteria. It can ONLY be contracted from the environment.
If infected, patients will experience pneumonia-like symptoms approximately 2 to 10 days after exposure to the bacteria. Treatment for Legionnaires Disease involves anti-biotics and patients are often hospitalized. The death rate for those infected with Legionnaires disease is 5-30%, according to the CDC.
