A concerning health issue is emerging along Australia’s coastline as cases of Buruli ulcer, a flesh-eating disease, appear to be on the rise. This disease, identified in Australia since the 1940s, has traditionally been reported in regions like the Northern Territory and far-north Queensland. However, an uptick in cases within Victoria—where reports indicate nearly daily occurrences—coupled with new instances in a southern New South Wales (NSW) coastal town, has caught the attention of health researchers.
Recent studies suggest that Buruli ulcer may now be endemic in Batemans Bay, a town located approximately 110 kilometers southeast of Canberra. The research team analyzed two confirmed cases from 2021 and 2023, alongside testing 27 samples of faeces from local possums, which are believed to be the primary carriers of the bacteria responsible for the ulcer. Mosquitoes also play a crucial role in transmitting the bacteria to humans.
The findings, published in the peer-reviewed journal PLOS Neglected Tropical Diseases, indicate that local possums in Batemans Bay have been found to carry the bacteria. The distinct strains identified in Batemans Bay differ from those prevalent in Victoria, highlighting the unique nature of this emerging outbreak.
Buruli ulcer often starts as a minor insect bite that can take weeks or months to develop into an ulcer. Timely diagnosis and treatment are essential to prevent severe skin and tissue loss. Reports include serious cases, such as a 94-year-old man who required the amputation of a finger due to the disease.
Researchers are concerned that, given the ecological similarities between coastal areas of Victoria and southern NSW, health authorities may soon face a broader expansion of Buruli ulcer cases. The study involved a collaborative effort by experts in infectious diseases, pathology, and research across several Australian states.
While the emergence of Buruli ulcer in new areas raises alarm, it also brings attention to the importance of public awareness and early diagnosis, which can significantly reduce the disease’s impact. With ongoing research and collaboration, there is hope that health organizations will develop effective strategies to manage and mitigate the spread of this disease in vulnerable communities.
In summary, as researchers continue to monitor this situation, education and vigilance will be key in combatting the potential spread of Buruli ulcer across Australia’s coastal regions.
