Flesh-Eating Ulcer: A New Threat Spreads Along Australia’s Coastline

A concerning health issue is emerging along Australia’s coastline—Buruli ulcer, a flesh-eating disease that can cause serious disfigurement, appears to be spreading, particularly in Victoria and the southern coastal area of New South Wales (NSW). Known since the 1940s, this disease has traditionally been linked to Northern Territory and far-north Queensland, but current trends suggest a worrying increase in cases.

In Victoria, nearly daily reports of this ulcer have raised alarms, while it has seemingly become endemic in Batemans Bay, NSW, located about 110 kilometers southeast of Canberra. Recent studies have revealed two documented cases in Batemans Bay—one in 2021 and the other in 2023—alongside analyses of 27 samples of possum feces, a primary reservoir for the bacterium that causes Buruli ulcer.

Researchers warn that the clustering of cases could indicate a broader expansion of the disease in NSW, akin to the troubling patterns seen in Victoria, where community transmission is more pronounced. The findings confirmed that the bacteria responsible for the ulcer’s onset are indeed present in local possums, which, combined with mosquito activity, pose significant risks to human health.

This ulcer often starts as what appears to be an insect bite but can develop into severe ulceration if not promptly treated. One notable case from Batemans Bay involved the amputation of a 94-year-old man’s ring finger due to a serious lesion. This underscores the urgency for early diagnosis to prevent severe tissue loss.

As researchers study the reasons behind the sporadic human cases occurring across large distances, they emphasize the importance of vigilance among local health authorities. With the animal and insect populations in southern NSW resembling those found in endemic areas of Victoria, health officials are advised to be prepared for potential outbreaks.

Overall, while the situation is grave, proactive research and early detection efforts can play a crucial role in managing and possibly curtailing the spread of this disease. Awareness and community engagement will be pivotal in combating Buruli ulcer as it poses challenges along Australia’s coastal communities.
