  Description

Legionellosis is a life-threatening infectious disease caused by a bacterium called Legionella. In most of cases it is caused by Legionella pneumophila. There are approximately 35 Legionella species known that produce the disease.

The bacteria are common in natural water sources but they may also be found in urban water systems where the bacteria can grow under favorable conditions at temperatures between 25 and 45 °C (77 and 113 °F), e.g. cooling towers or hot water systems. The bacteria can survive for several months in those wet environments.  

People can get the bacteria by inhaling water or small drops suspended in the air. The transmission of Legionnaires' disease is not completely understood.

Legionellosis can have two different forms:

- Legionnaires' disease, also known as Legion Fever, is the more severe form of the infection because it affects primarily the lungs causing pneumonia, a condition in which some of the lungs' air sacs fill with fluid or pus, so air is excluded. Legionnaires' disease mainly affects older adults and people with weakened immune systems. If untreated, Legionnaires' disease can be fatal. First symptoms appear 2 to 14 days after the exposure to legionella bacteria.

 - Pontiac fever. Only produces a milder illness resembling acute influenza. Usually, the fever clears on its own in 2 to 5 days. The first symptoms generally appear a few hours after  the patient has been exposed to the bacterium

Some people can be infected with the Legionella bacteria and have only mild symptoms or no illness at all.

  Diagnosis

Diagnosis can be confirmed if the legionella bacteria is found after the following tests:

- Blood tests.

- Sputum culture.

- Urine tests.

Complementary tests may include:

- Bronchoscopy.

- Lumbar puncture.

- Chest X-ray.
