A concerning public health issue is emerging in Australia, as cases of Buruli ulcer, a flesh-eating disease, appear to be spreading along the coastline. This ulcer can lead to permanent disfigurement and currently lacks any documented prevention methods.
The Buruli ulcer has been present in Australia since the 1940s, primarily recorded in the Northern Territory and far-north Queensland. However, a recent rise in cases in Victoria, where nearly one case is reported daily, and new instances in a coastal town in southern New South Wales (NSW) have prompted further investigation by researchers.
Recent studies indicate that Buruli ulcer may have become endemic in Batemans Bay, located about 110 kilometers southeast of Canberra. Researchers examined the town’s only two documented cases, reported in 2021 and 2023, and analyzed 27 samples of possum feces. Possums are believed to be the main reservoir of the bacteria that cause the ulcer, with mosquitoes facilitating transmission to humans.
The research team noted that the cases in Batemans Bay could be indicative of a larger disease spread in NSW, similar to what has been seen in Victoria. Their findings confirm the presence of the bacteria in local possums through positive samples of their excreta.
Interestingly, the bacteria identified in Batemans Bay differ from those found in the most endemic regions of Victoria, including Melbourne and Geelong. The Buruli ulcer often presents initially as an insect bite, but can take weeks or even months to develop into an ulcerated lesion. Prompt diagnosis and treatment are essential to prevent serious skin and tissue damage. In one reported case in Batemans Bay, a 94-year-old patient’s ring finger was amputated after the skin lesion worsened.
Researchers point out that the similarities in wildlife and insect populations between coastal Victoria and southern NSW suggest that health authorities may need to prepare for a broader spread of ulcer-endemic regions. Despite the alarming rise in cases, the collaborative research efforts among infectious disease specialists across Victoria, NSW, and the Australian Capital Territory signal an active commitment to understanding and controlling the disease’s progress.
As researchers delve deeper into the situation, there is hope that improved awareness and diagnosis will help mitigate the impact of this troubling disease in affected areas. Raising public awareness of early symptoms and encouraging vigilance in recognizing changes can empower communities to take proactive measures against the Buruli ulcer.
