Facts on Legionnaires' outbreaks

QUICK FACTS ON LEGIONNAIRES' DISEASE:

* Legionnaires' disease is a rare form of pneumonia caused by Legionella bacteria, which is found throughout the environment.

* The bacteria is commonly found in potting mix, spas, water systems, and cooling and heating systems as well as natural bodies such as lakes and hot springs.

* People can catch the infection by breathing in fine droplets of water containing the bacteria, but not everyone who comes into contact with it becomes sick.

* Those most at risk are over 50 years of age, heavy smokers, those with chronic illness such as lung disease or diabetes, and those with compromised immunity.

* Symptoms include headache, chills, muscle aches and pains followed by respiratory problems and pneumonia over three to four days.

* Other symptoms can include diarrhoea, mental confusion and kidney failure.

* Twenty-six people have contracted the disease in Victoria so far this year.

* Early treatment can prevent the disease from becoming severe. It is fatal in up to 10 per cent of cases.

* Anyone concerned about symptoms is advised to contact their GP or hospital or contact the DHHS Communicable Disease Prevention and Control Unit on 1300 651 160.
