Legionnaires' Disease Outbreak Prompts Health Alert for Sydney's CBD
A recent health alert has been issued for Sydney's central business district (CBD) after six people contracted Legionnaires' disease. This outbreak has raised concerns, particularly for those who have been in the area over the past few weeks. Health authorities are urging anyone who has visited the CBD recently to remain vigilant for symptoms associated with this potentially deadly disease.
Legionnaires' disease is caused by the bacterium Legionella pneumophila , which can lead to a severe form of pneumonia. The disease is not contagious and is typically contracted through inhaling aerosolized water particles contaminated with the bacteria. While the exact source of the outbreak in Sydney’s CBD is still under investigation, the public health unit believes the common link among the six patients is their exposure in the city centre.

The symptoms of Legionnaires' disease can take anywhere from two to ten days to manifest, and they include fever, chills, a persistent cough, and shortness of breath. In some cases, it can lead to severe respiratory issues like pneumonia, which can be life-threatening, particularly for vulnerable groups such as the elderly or those with pre-existing health conditions like lung disease or weakened immune systems.
NSW Health is working closely with the City of Sydney to pinpoint the source of contamination. Cooling towers, often found in large buildings, are one of the known culprits for Legionella outbreaks. These towers can become breeding grounds for the bacteria if they are not properly maintained, leading to the release of contaminated water vapor into the air. The authorities are currently reviewing maintenance records of these cooling systems to identify any potential risks and to ensure that necessary cleaning measures are taken.
While no deaths have been reported in this particular outbreak, similar incidents in other parts of Australia have been fatal. In Melbourne, a significant outbreak in 2024 resulted in multiple hospitalizations and deaths. The increase in such cases across the country has prompted heightened awareness and ongoing investigations into how the bacteria spreads.
Health experts emphasize that people who have been in the CBD recently and develop symptoms should seek medical attention immediately. It is crucial for individuals to monitor their health closely, especially if they are at higher risk, and get tested as soon as symptoms appear. Public health campaigns and awareness efforts are key in controlling the spread of the disease and preventing further cases. As authorities continue to track the outbreak, they are also advising building owners to maintain their cooling towers in line with strict health regulations to prevent similar incidents in the future.
This alert serves as a reminder of the importance of regular maintenance and monitoring of public health systems to protect the community from such outbreaks. With more than 500,000 people working in the CBD, the swift action by health authorities is essential to ensuring public safety and preventing further infections.
