Millions on alert: Surge in disease cases triggers investigation from Department of Health
- Replies 2
As the city of Melbourne grapples with a sudden and concerning outbreak of Legionnaires' disease, millions of residents are being urged to stay alert for symptoms of this potentially fatal illness.
The Victorian Department of Health reported a 'significant increase' in cases, with 33 confirmed and another 10 suspected in just four days.
This alarming surge has predominantly affected the city's northern and western suburbs, prompting health officials to issue an urgent call to action for the community.
Legionnaires' disease, caused by the Legionella bacteria, can lead to severe pneumonia and, in most cases, requires hospitalisation.
Victorian Chief Health Officer Dr Clare Looker expressed her concern, noting the unusual spike in cases and the severity of the illness, with many patients currently in intensive care units.
‘This is a nasty type of pneumonia ... so people can become quite sick, quite quickly,' she said.
‘We are concerned. This is a significant increase on normal.’
‘Most of our cases at the moment are in hospital, a number in ICU... so they're critically unwell.’
‘As soon as we have a better sense of particular locations of concern, we will be sharing that.’
The health department is diligently working to pinpoint the outbreak's source, focusing on local cooling towers and other potential breeding grounds for the bacteria.
‘People who live in, work in or have visited metropolitan Melbourne and surrounding areas, and develop symptoms of Legionnaires' disease, should seek urgent medical care,’ the statement said.
Symptoms to watch for include fever, chills, cough, headache, muscle aches, and pains. In some instances, individuals may also experience nausea, vomiting, diarrhea, and confusion.
These symptoms can manifest up to 10 days after exposure to the bacteria, which thrives in environments like potting mix and soils and can increase in bagged potting mix, mulch, and similar products.
It's crucial to understand that Legionnaires' disease is not contagious and cannot be spread from person to person.
‘Typically, people will almost always get it by breathing in fine droplets of water that contain the bacteria,’ Dr Looker continued.
‘Most often, we will see most of the big outbreaks are associated with cooling towers, so big industrial air conditioners,’
The health department has identified those most at risk as individuals over 40, smokers, and those with chronic lung disease, weakened immune systems, or other underlying medical conditions such as heart, liver, or kidney disease and diabetes.
The outbreak is believed to be caused by serogroup 1, a strain of Legionella that can be identified through a urinary antigen test.
In related news, health authorities advised gardeners to wear masks and gloves to prevent contracting Legionnaires' disease from potting mix, mulch, and compost.
New South Wales Health reported several cases of the disease since last year. For more details, read here.
