What is Legionella?

Legionella is a bacterium that can cause Legionnaires’ disease, a potentially fatal lung infection (pneumonia). Legionnaires’ disease is caught by breathing in small droplets of contaminated water, from a shower head for example. It is not contagious and cannot be spread directly from person to person. The condition is called Legionnaires’ disease because it was first identified after a mass outbreak at a hotel hosting a convention of a veteran organization known as the American Legion.

Causes of Legionnaires’ disease

Legionella bacteria is commonly found (often in low numbers) in sources of water, such as rivers and lakes. 

The bacteria sometimes find their way into artificial water supply systems such as:
Air conditioning systems, Hot and cold water services 

Given the right conditions, Legionella bacteria can rapidly spread and contaminate these water systems. Large buildings, such as hotels, hospitals, 

museums and office blocks, are more vulnerable to Legionella contamination because they have larger, more complex water supply systems in which 

Legionella contamination can quickly spread. There are strict regulations regarding the maintenance and control of water supply systems, such as either 

keeping the water cooled below 20ºC (68ºF) or heated above 60ºC (140ºF) to prevent an outbreak of Legionnaires’ disease. The water should also be kept

free of any impurities and never allowed to stagnate (lose its freshness from not moving).
