A fourth case of the potentially deadly Legionnaires’ disease has been reported in Sydney, prompting health authorities to issue a fresh public alert following a recent increase in diagnoses.
All four affected individuals, including three cases confirmed earlier this week, had spent time in the Clarence Street area near Wynyard in Sydney’s central business district between December 9 and December 18.
Legionnaires’ disease occurs when people inhale water droplets contaminated with Legionella bacteria, commonly found in sources such as cooling towers on top of large buildings. NSW Health explained that exposure can occur when contaminated water particles from cooling systems become airborne and are breathed in.
Dr Vicky Sheppeard said symptoms may develop up to 10 days after exposure and can include fever, chills, coughing and shortness of breath, potentially leading to severe chest infections such as pneumonia. She noted that older people, smokers, and those with underlying lung or serious health conditions are at higher risk.
All four patients are currently receiving treatment in hospital, and investigations are underway to identify the source of the outbreak. Building managers in the CBD have been urged to inspect and maintain their cooling towers as a precaution.
NSW Health has advised anyone who visited the Clarence Street and Wynyard areas since December 9 to remain vigilant for symptoms, which can appear between two and 10 days after initial exposure.
