A concerning healthcare issue is arising along Australia’s coastline with the spread of Buruli ulcer, a flesh-eating infection that can result in severe disfigurement and currently has no established prevention methods. Although cases of this ulcer have been documented in Australia since the 1940s, primarily in Northern Territory and far-north Queensland, a recent surge in cases in Victoria—where a new instance is reported almost daily—and the presence of the disease in the coastal town of Batemans Bay in southern New South Wales (NSW) has captured researchers’ attention.
Recent analyses indicate that Buruli ulcer has now become endemic in Batemans Bay, a coastal town located approximately 110 kilometers southeast of Canberra. Researchers examined the town’s only two recorded cases, dating back to 2021 and 2023, as well as 27 samples collected from local possum feces. It is believed that possums serve as the primary reservoir for the bacteria responsible for the ulcer, while mosquitoes play a critical role in transmitting the disease to humans.
The findings published in the peer-reviewed journal PLOS Neglected Tropical Diseases highlight that the strains of bacteria found in Batemans Bay differ from those circulating in Victoria’s most affected areas, including Melbourne and Geelong. The researchers warn that the new cases could signify an impending increase in the disease’s prevalence throughout NSW, akin to what has been observed in Victoria.
Buruli ulcer often presents initially as an innocuous insect bite, but if untreated, it can deteriorate significantly, leading to serious skin and tissue loss. One alarming case involved a 94-year-old man from Batemans Bay whose ring finger was amputated following a severe infection. Researchers are trying to understand the factors behind the emerging cases in geographically disparate areas, as the similarities in wildlife and insect populations between coastal Victoria and southern NSW suggest that NSW could be on the brink of a broader outbreak.
As researchers continue to investigate and monitor the situation, early recognition and prompt medical attention remain vital in preventing severe outcomes associated with Buruli ulcer. Health authorities are urged to remain vigilant as the disease landscape evolves in this region.
In summary, while the emergence of Buruli ulcer in southern NSW poses serious health risks, ongoing research efforts may lead to a better understanding of the disease and prompt effective public health responses. There is hope that increased awareness and early intervention can mitigate the spread and safeguard the communities at risk.
