The three women and four men, ranging in age from their 20s to 70s, independently visited locations in the CBD between Bathurst Street, Sussex Street, Elizabeth Street and Circular Quay in the 10 days prior to their symptoms. All have been admitted to hospital for treatment of pneumonia.
Mark Ferson from NSW Health says that people shouldn’t panic, however that individuals presenting with symptoms should see their doctor immediately.
Symptoms of Legionnaires’ disease
Legionnaires’ disease is a severe form of pneumonia caused by the Legionella bacteria. The symptoms can vary but often include:
1. Cough: Persistent cough, which may produce mucus or blood.
2. Shortness of Breath:
3. Chest Pain
4. Fever often exceeding 40°C
5. Intense shivering and chills
6. Muscle aches and fatigue
7. Severe headache, often accompanied by confusion
8. Gastrointestinal symptoms like nausea, vomiting, and diarrhoea
9. Weakness and fatigue
10. Loss of appetite
The symptoms of Legionnaires’ disease usually appear 2 to 10 days after exposure to the bacteria. It’s important to note that Legionnaires’ disease can be a serious condition and may require hospitalisation.
If you experience symptoms suggestive of Legionnaires’ disease, especially if you have been in environments with a higher risk of Legionella exposure (such as hot tubs, air conditioning systems, or water systems in large buildings), seek medical attention promptly.
NSW Health environmental health officers are working closely with the City of Sydney Council to inspect cooling towers. Review of maintenance records of cooling towers in the CBD area will also help determine further towers to be inspected and sampled.
Legionnaires’ disease is not transmitted from person to person, and the majority of cases are isolated incidents associated with exposure to contaminated water sources.
If you are diagnosed with pneumonia, tell your doctor if you have been to an outbreak location or handled potting mix recently.
