A concerning increase in cases of Buruli ulcer, a flesh-eating disease known to cause permanent disfigurement, has been observed along Australia’s coastline, particularly in Victoria and a coastal town in southern New South Wales (NSW). This disease, which has no known prevention methods, has been present in Australia since the 1940s, primarily noted in the Northern Territory and far-north Queensland.
Recent reports indicate a near-daily occurrence of new cases in Victoria, while two cases in Batemans Bay, approximately 110 kilometers southeast of Canberra, have raised alarms among researchers. Their analysis suggests that the bacteria causing the ulcer has become endemic in this coastal region.
Researchers examined the only two reported cases in Batemans Bay, dated 2021 and 2023, along with 27 samples from local possums, believed to be the primary reservoirs of the bacteria. Mosquitoes are thought to play a significant role in transmitting the disease to humans. The research team emphasized that the presence of the bacteria in local possum excrement confirms its existence in the area, potentially foreseeing an expansion of Buruli ulcer cases in NSW similar to that seen in Victoria.
Notably, the strain of bacteria found in Batemans Bay differs from that prevalent in the most endemic areas of Victoria, including Melbourne and Geelong. The initial symptoms of Buruli ulcer can resemble an insect bite, which may take weeks or months to develop into an ulcer. Early detection and diagnosis are crucial to managing the disease and preventing severe tissue loss.
A case in Batemans Bay highlighted the severity of the disease; a 94-year-old man required the amputation of his ring finger due to extensive ulceration caused by the bacteria. Researchers noted that the similarities in wildlife and insect populations between coastal Victoria and southern NSW could indicate a progressive spread of the disease in these new areas.
The comprehensive research, conducted by a team of infectious disease specialists, pathologists, and researchers from various regions, aims to understand the reasons behind the emergence of cases hundreds of kilometers apart.
While the growing number of cases of Buruli ulcer is alarming, continued research and awareness of the disease may contribute to better understanding and management, ultimately leading to improved outcomes for those affected.
In summary, researchers are on high alert for potential growth in Buruli ulcer cases in coastal regions of NSW, highlighting the need for vigilance in early diagnosis and understanding of this flesh-eating disease. There is hope that with increased awareness and research, strategies can be developed to combat this disease effectively.
