What is legionella? 

Legionella is a bacteria which occurs naturally in slow-moving or stagnant water, and is commonly found in cooling towers, air conditioning systems, spa pools and hot and cold water systems. The bacteria is the root cause of legionellosis – the collective name for illnesses caused by legionella bacteria, including the potentially fatal legionnaire’s disease. 

Legionnaire’s disease is a serious lung infection, which if left untreated can become fatal. Symptoms include coughing, shortness of breath and fever, as well as muscle pain, headaches and confusion.
