UPDATE: An urgent health alert has been issued following three confirmed cases of legionnaires’ disease in the Sydney CBD. The affected individuals, who are not connected, were hospitalized after visiting the area around Clarence St between December 9 and December 18, 2023.
NSW Health is urging anyone who was in the vicinity during this period to be vigilant and monitor for symptoms of this potentially deadly infection. Legionnaires’ disease, caused by the legionella bacteria, can lead to severe respiratory issues, including fever, chills, cough, and shortness of breath. If left untreated, it can be fatal.
Health authorities emphasize that the disease is not transmitted from person to person. Instead, it often arises from environmental sources, such as contaminated water from cooling towers. As a precaution, health officials are collaborating with the City of Sydney to investigate the cooling towers in the area.
Mark Ferson, acting director of the South Eastern Sydney Local Health District, stated that the source of the infections remains unknown, and it is possible that the cases are unrelated. He explained, “People are exposed if contaminated water particles from a cooling system are in the air and then breathed in.”
Symptoms can manifest up to 10 days after exposure, making it crucial for those who visited the area to stay alert. Individuals at higher risk include the elderly, those with pre-existing health conditions, and smokers.
Authorities are conducting thorough investigations to prevent further cases. Residents and visitors are encouraged to seek medical attention if they experience any concerning symptoms.
Stay tuned for updates as this situation develops. Your health and safety are paramount.
