Legionella is a commonly occurring bacteria found in both natural and artificial water systems. In Legionnaires’ disease, a serious and potentially fatal form of pneumonia, the infection is caused by inhaling contaminated water droplets containing Legionella bacteria.
There are a number of elements which could be the catalyst for Legionella proliferation in a water distribution system, including; incoming water quality, plumbing systems, heated water systems, equipment and installations. Facility managers and care staff at hospitals, aged care facilities and health service centres need sufficient information in order to protect patients and residents of their buildings.
