Legionnaires’ Disease update

Friday, 20 January 2017

SA Health has been notified of two further cases of Legionnaires’ disease bringing the total number of cases in this latest cluster to six.

While no single common location between the six cases has been identified, it appears the majority of the cases may have contracted Legionnaires’ disease in the Adelaide CBD over the New Year period.

SA Health’s Acting Chief Public Health Officer Dr Kevin Buckett said since the cases were contracted around the same time and action has already been taken by health authorities in response to the situation, the ongoing risk to public health is minimal.

“Given all the cases had the onset of Legionnaires’ disease around the New Year period, it would appear they are related,” Dr Buckett said.

“We anticipate the action taken by councils and building operators this week will have reduced any ongoing to risk to public health.

“As is often the case with Legionella bacteria, identifying the source or sources can be difficult especially when there is not a common location amongst all the cases.

“Contaminated cooling towers are a common source of Legionnaires’ disease and public health action to ensure cooling towers are properly maintained and disinfected across multiple council areas is continuing.”

The two latest cases of Legionnaires’ disease are in a 26 year old female and a 63 year old male.
