Legionnaires Disease

What is Legionnaires Disease?

Legionnaires disease is a type of pneumonia caused by a bacteria called Legionella pneumophila.

Pneumonia is an infection that causes swelling of the air sacs in the lungs. The air sacs may fill with fluid causing coughing with phlegm, fever, chills, and difficulty breathing. A variety of organisms, including bacteria, viruses and fungi, can cause pneumonia.

The very first outbreak was recorded in Spain in 1973, however, Legionnaires disease was only named after an outbreak during the conference at a hotel in Philadelphia USA 1976 where attending members of the American Legion (Soldiers) fell ill.

Symptoms show 2 to 10 days after infection and even up to 16 Days.

Legionella pneumophila

Legionella are bacteria that live naturally in water and soil. Like most bacteria, there are harmless species that live in the environment and those that are harmful to us.

Legionella pneumophila is the harmful bacteria that causes Legionnaires disease.

Legionella are that live in natural water sources such as lakes and rivers, as well as artificial or man-made water systems. It is when the bacteria get into these water systems that they are able to cause Legionnaires disease.
