In an alarming development, health authorities in Victoria, Australia have reported a significant increase in cases of the rare but potentially devastating Buruli ulcer infection. The flesh-eating bacterial disease, which can lead to severe skin ulcers and tissue damage if left untreated, has been spreading in the Melbourne suburb of Ascot Vale, prompting an urgent advisory from the state’s chief health officer, Professor Ben Cowie.
Surge in Buruli Ulcer Cases Raises Concerns
According to health department data, Victoria has witnessed a worrying rise in Buruli ulcer notifications, with 344 cases reported as of December 17, 2024. This marks a substantial increase compared to previous years, with 362 cases in 2023, 338 in 2022, 286 in 2021, and 217 in 2020. The recent surge in infections linked to Ascot Vale has health officials on high alert.
Cases remained high across the state. The disease is spreading geographically across Victoria and is no longer restricted to specific coastal locations.

Recognizing Buruli Ulcer Symptoms
Buruli ulcer, caused by the bacterium Mycobacterium ulcerans, typically begins as a painless lump or wound that can easily be mistaken for an insect bite. However, over time, the lesion slowly develops into a destructive skin ulcer that can lead to significant tissue loss and damage if not promptly treated. While the infection can occur anywhere on the body, it is most commonly found on exposed areas of the limbs.
- Early stages: Painless lump or wound, often resembling an insect bite
- Progression: Lesion slowly develops into a destructive skin ulcer
- Common locations: Exposed areas of the limbs
- Risk factors: Outdoor activities, exposure to mosquitoes
Preventing Buruli Ulcer Infections
To minimize the risk of contracting Buruli ulcer, Professor Cowie advises residents and visitors to Victoria to take the following precautions:
- Use personal insect repellents to deter mosquitoes, which may play a role in transmitting the disease
- Cover up with loose, light-colored clothing to minimize skin exposure
- Avoid mosquito-prone areas or being outdoors during peak biting times
- Seek prompt medical attention for any suspicious lumps or wounds
Prompt Treatment is Key
Early diagnosis and treatment of Buruli ulcer are critical to preventing severe complications and long-term disability. Professor Cowie emphasizes that prompt treatment can significantly reduce skin loss and tissue damage, and may help avoid the need for more intensive interventions. The incubation period for the disease varies widely, ranging from four weeks to nine months, making ongoing vigilance essential.

A Growing Threat in Victoria and Beyond
While Buruli ulcer has been known to occur in Australia since the 1940s, the recent spike in cases and geographic spread in Victoria is particularly concerning. The disease has also been reported in other parts of the country, including New South Wales, where researchers believe it may have become endemic in the coastal town of Batemans Bay.
As health authorities work to contain the outbreak and raise awareness about the risks associated with Buruli ulcer, it is crucial for residents and healthcare providers to remain vigilant. By taking appropriate preventive measures, promptly seeking medical attention for suspicious lesions, and supporting ongoing research efforts, the community can help combat this concerning public health threat.
The spread of Buruli ulcer in Melbourne serves as a stark reminder of the ever-present dangers posed by infectious diseases, even in developed urban areas. As climate change and other factors contribute to the emergence and resurgence of various pathogens, it is more important than ever to prioritize public health preparedness and invest in robust surveillance and response systems. Only through concerted efforts across all levels of society can we hope to mitigate the impact of diseases like Buruli ulcer and safeguard the well-being of our communities.
