A man in his 80s died and six other people were taken to the hospital because of an outbreak of Legionnaires’ disease in Potts Point, Sydney. This event has brought attention to the dangers of Legionella bacteria, which can cause severe pneumonia-like symptoms, and the difficulties that public health officials have in controlling such outbreaks. In this blog, we’ll talk about the outbreak, what it meant, and what people can do to stop Legionnaires’ disease from happening again.
What is the disease Legionnaires’?
The Legionella bacteria cause Legionnaires’ disease, which is a deadly type of pneumonia. It mostly affects the lungs, but it can also infect other organs like the heart and kidneys. Legionnaires’ disease can kill you if you don’t get treatment, unlike the flu.
People get sick when they inhale in water droplets or mist that have the Legionella bacteria in them. Cooling towers on big buildings, hot tubs, whirlpools, and even fountains are all places where people may become sick. The disease doesn’t spread from person to person; it spreads through being around it.
Symptoms of Legionnaires’ Disease
Legionnaires’ disease symptoms usually start to show up 2 to 10 days after being exposed and can include:
- Very high fever (104°F or 40°C)
- Pain in the head and muscles
- Cough that can bring up mucus or even blood at times
- Chest pain and trouble breathing
- Feeling confused, sick, throwing up, and having diarrhoea
If not treated, it can cause serious issues like septic shock, lung failure, and acute kidney failure. If these problems aren’t dealt with properly, they could lead to death.
The Potts Point Outbreak – A Timeline of Events
A man in his 80s from Potts Point got sick in late June 2024 and was taken to the hospital with symptoms of Legionnaires’ disease. He sadly died from the infection although he got medical help. He was one of seven people in the Potts Point area who got the disease, and six of them enjoyed to go to the hospital. Five of the six patients have been sent home, but one is still in the hospital.
This outbreak has made individuals worried about the safety of public water systems, especially cooling towers, which are often connected to Legionella bacteria. The health department in the area has sent their deepest condolences to the family of the one who died and asked everyone to stay alert.
Investigating the Cause of the Outbreak
The City of Sydney and the South Eastern Sydney Local Health District (SESLHD) are looking into where the Legionella infection came from. People who got sick and didn’t know each other may have been exposed to the same source in the area, based to what is known.
There have been no Legionella bacteria found in the area yet, but tests are still going on. To make sure that the bacteria don’t get into the water systems, SESLHD has asked building owners to clean their cooling towers. These steps are essential for stopping the spread of Legionnaires’ disease.
What causes Legionnaires’ disease to spread?
People mostly get Legionnaires’ disease by breathing in mist or droplets from water sources that have Legionella bacteria in them. Some places where this could come from are:
- Cooling towers in big buildings
- Whirlpools and hot tubs
- Water features and fountains for decoration
- Sinks and showerheads
The disease usually doesn’t spread from person to person, which is why outbreaks happen in places where people share water systems, like big public buildings or apartment complexes. The mist that comes from cooling towers is a common way for the bacteria to pass on through the air.
Who is most likely to get Legionnaires’ disease?
Most healthy people who come into contact with Legionella bacteria don’t get sick, but some groups are more likely to get sick:
- People over 50 are more likely to get sick.
- Smokers: Smoking hurts the lungs, causing it more likely that you will get a respiratory infection.
- People whose immune systems are weak: HIV/AIDS and chemotherapy are two examples of conditions or treatments that can make it harder for the body to fight infections.
- People with long-term lung problems, such as emphysema, chronic obstructive pulmonary disease (COPD), or asthma, are more likely to get sick.
- People with diabetes and kidney disease: People with chronic conditions like diabetes and kidney disease are also more likely to get infections like Legionnaires’ disease.
What are health officials doing to stop the outbreak?
Health officials are taking a number of important steps in response to the outbreak in Potts Point:
- Cooling Tower Inspections: Authorities have told building owners to clean their cooling towers twice to get rid of any possible contamination.
- Public Health Advisory: If you have been to Potts Point and start to show signs of Legionnaires’ disease, you ought to see a doctor right away.
- Ongoing Testing: SESLHD is still keeping an eye on the area and doing tests to find any more locations where Legionella bacteria might be hiding.
- Health Education: People and businesses are acquiring about the dangers of Legionella and how essential it is to keep water systems safe to stop more outbreaks.
How to avoid Legionnaires’ disease
Outbreaks like the one in Potts Point are scary, but they don’t have to happen. There are things you can do to lower your risk of getting Legionnaires’ disease, both in buildings and at home:
- In Buildings: Owners of buildings should set up a water management programme to make sure that cooling towers and water systems are well taken care of. Cleaning and disinfecting these systems on a regular basis is crucial to stop the growth and spread of Legionella bacteria.
- At Home: Homeowners should regularly clean and maintain their water systems, like hot tubs and showers, to keep bacteria from building up.
- In Cars: Using only real windscreen cleaner fluid instead of water in cars stops Legionella from growing in the wiper fluid tanks.
- Public Awareness: Local health departments can teach people about the dangers of diseases that spread through water and urge them to report any signs of illness right away.
Signs to Watch Out For
People need to know the signs of Legionnaires’ disease, especially if they have recently been to areas where there was an outbreak, like Potts Point. Some common signs are:

Dealing with the Risks and Making Certain Everyone Is Safe
The Legionnaires’ disease outbreak in Potts Point is a clear example of how dangerous water systems can be and how important it is to keep them in good shape. It also shows how vital it is for both the government and the public to be more aware and watchful. Health officials are working hard to find the source and stop more cases from occurring while the investigation is still going on.
People who live or work near cooling towers or other water systems need to clean and disinfect them on a regular basis to lower the risk of Legionella growth. If you start to show signs of Legionnaires’ disease, it’s very important to get treated and diagnosed right away to avoid serious problems.
