A concerning trend has emerged along Australia’s coastline as the flesh-eating Buruli ulcer appears to be spreading, particularly in Victoria and now in a coastal town in New South Wales (NSW). This skin infection, which can lead to severe disfigurement and has no known prevention, has been recorded in Australia since the 1940s, primarily in the Northern Territory and far-north Queensland.
Currently, Victoria is experiencing an alarming increase in the number of reported cases, with nearly one case being documented each day. The situation has drawn attention from researchers, particularly with the recent emergence of cases in Batemans Bay, located approximately 110 kilometers southeast of Canberra. The analysis indicates that Buruli ulcer may now be endemic in this area.
Researchers investigated Batemans Bay’s two reported cases from 2021 and 2023 and conducted tests on 27 samples from local possum droppings. It is believed that possums serve as the primary reservoir for the bacteria that causes the ulcer, with mosquitoes playing a crucial role in transmitting the disease to humans.
The researchers stated that recent cases in Batemans Bay could signal a significant spread of the disease in NSW, comparable to what has been seen in Victoria. They have confirmed the presence of the ulcer-causing bacteria in local possums through testing of possum excreta samples.
The study indicates that the strain of bacteria found in Batemans Bay differs from those prevalent in the heavily affected regions of Victoria, such as Melbourne and Geelong. The initial symptoms of the ulcer present like an insect bite, often taking weeks or months to develop into a serious open wound. Early detection is vital for preventing extensive skin and tissue loss, as demonstrated in one recent case involving a 94-year-old man whose condition required the amputation of his ring finger due to severe skin lesions.
Similar wildlife and insect populations in coastal regions of Victoria and southern NSW suggest that health authorities may be bracing for a further spread of the ulcer in NSW. Although various factors have contributed to cases emerging in locations far apart, the connection between the different regions continues to intrigue researchers.
This situation highlights the importance of awareness and research in continuing to protect public health. With concerted efforts from healthcare professionals and researchers, there is hope that early detection and treatment strategies will be developed to manage and potentially contain the spread of Buruli ulcer.
