Where does legionella come from?

Legionella

Legionella bacteria are found in soil and fresh water sources in the natural environment. It grows readily at temperatures ranging between 20 and 50°C. As the name suggests, it’s also the species that causes Legionnaires’ disease. Symptoms of the disease include breathing difficulties, dry cough, flu-like symptoms and in some cases vomiting, diarrhoea and delirium.

The bacteria generally only cause illness when they begin to flourish in man-made water systems such as cooling towers, hot/cold water systems, fountains and in equipment that produces moist air such as air conditioning units.
