Aussie city faces severe health crisis as Legionnaires' disease outbreak claims second victim
- Replies 12
Australians are currently facing a health crisis of significant proportions, with health officials issuing urgent warnings as the situation escalates.
A recent surge marks one of the most severe outbreaks in two decades, prompting increased vigilance and public health measures to address the growing concern.
Authorities are working swiftly to contain the spread and provide guidance to the community amidst this critical health crisis.
Melbourne is grappling with a significant outbreak of Legionnaires' disease, with the disease claiming its second victim.
This severe form of pneumonia, caused by the legionella bacterium, has already taken the lives of two residents, including a woman in her 90s and now a man in his 60s.
The man’s death came just days after the first victim’s on Tuesday, July 30.
There are currently 77 confirmed or suspected cases—the highest number of cases since the severe Melbourne Aquarium outbreak in 2000, which affected at least 125 people and resulted in four deaths.
However, Victoria's Chief Health Officer Clare Looker indicated that the situation seemed to be stabilising.
‘We've definitely seen a decrease in the speed with which notifications are coming in and definitely a clustering of those symptoms and onsets from those earlier dates,’ she said.
Elizabeth Hartland, Director of the Hudson Institute of Medical Research, stated that the coming days will be critical.
‘It is a very significant outbreak for Australia, with these numbers of people,’ she pointed out.
Ms Hartland noted that the outbreak is occurring at an unusual time during winter, a period when air conditioners—where the disease typically thrives—are used less frequently.
She also mentioned that the hospitalisation rate, with 59 out of 60 confirmed cases having been or currently being in hospital, is also unusual.
‘They’ve either had a very large dose of the bacteria, so something is heavily contaminated, or there’s something inherently more virulent about this particular strain of legionella,’ she speculated.
Health authorities are urgently testing several cooling towers in the Derrimut and Laverton North areas in an effort to identify the source of the outbreak.
Investigators have identified the two suburbs as potential sources of the outbreak, which may have affected people ‘up to several kilometres’ away.
The Bureau of Meteorology is being consulted to determine if weather conditions could have contributed to the rapid spread of the disease.
Dr Looker suspected that one of the 42 cooling towers in the area may be responsible for the sudden increase in cases, but she cannot confirm this until testing, which takes up to 10 days, is complete.
While over 100 cooling towers in a wider area could be tested for legionella, initial tests are focusing on the ‘highest priority’ locations.
Dr Looker indicated that there is a ‘high probability’ that the contaminated tower has already been disinfected by health officials ‘driven by some pretty compelling epidemiology’.
She stated that a previous investigation linked to the recent factory fire in Derrimut was ‘pretty unlikely’ to be related and added that the woman who died became ‘very suddenly unwell’ and passed away that same evening.
Most cases of Legionnaires' disease are associated with inhaling tiny water droplets containing the bacteria and are seldom transmitted from person to person.
Legionella is known to proliferate in cooling towers, air conditioning units, hot water tanks, water features, drinking water, swimming pools, and hot tubs.
Individuals over 40, smokers, and those with weakened immune systems are more prone to experiencing severe symptoms of the disease.
‘Legionnaires' disease can cause a chest infection with symptoms of fever, chills, cough, headache and muscle aches and pains,’ the Department of Health Victoria said in a statement.
‘Other atypical symptoms may include nausea, vomiting, diarrhoea and confusion.’
People who live, work, or have recently visited Melbourne's Metropolitan area and are showing symptoms were advised to seek medical attention and get tested immediately.
