A concerning flesh-eating ulcer known as Buruli ulcer is reportedly spreading along the coastline in Australia, particularly in the southeastern region. This ulcer has been present in Australia since the 1940s, primarily in places like Northern Territory and far-north Queensland, but recent developments indicate a rising incidence in Victoria, where cases now surface almost daily. Moreover, a new emergence of the disease has been noticed in Batemans Bay, a coastal town in southern New South Wales.
Recent analysis published in PLOS Neglected Tropical Diseases highlighted the potential for this disease to become endemic in Batemans Bay. Researchers examined the town’s cases from 2021 and 2023, as well as analyzed 27 samples of possum droppings, which are believed to be a primary reservoir for the bacteria causing this ulcer. Mosquitoes also play a crucial role in transmitting the bacteria to humans.
The research team warned that the rise in cases in Batemans Bay might signal a growing issue in New South Wales, similar to the situation in Victoria. They confirmed the presence of the bacteria in local possums through positive samples, distinguishing it from the strains found in more established endemic areas of Victoria.
The ulcer typically begins as an insect bite and can take a significant amount of time, sometimes weeks or months, to develop into a severe ulcer. Timely diagnosis is crucial to mitigate the risk of skin and tissue loss. Unfortunately, in one documented instance in Batemans Bay, a 94-year-old man had to undergo amputation of his ring finger due to a severe lesion.
Despite the alarming situation, there is a silver lining: the active research being conducted on the spread of this disease may lead to better understanding and awareness, ultimately improving early detection and treatment options. It’s vital for local health authorities to remain vigilant and proactive in addressing this evolving health concern, especially as wildlife and insect populations share similarities between coastal regions of Victoria and New South Wales.
In summary, while Buruli ulcer poses a significant public health challenge in Australia, the ongoing research efforts provide hope for better management and prevention of this disease in both current and future cases.
