Flesh-Eating Disease Threatens NSW Coastline: What’s Behind the Surge?

A concerning flesh-eating ulcer known as Buruli ulcer is seemingly on the rise along Australia’s coastline, with recent reports indicating that it has become endemic in the southern New South Wales coastal town of Batemans Bay. Originally recognized in Australia since the 1940s, this disease has been predominantly reported in Northern Territory and far-north Queensland. However, the emergence of frequent cases in Victoria—nearly one daily—coupled with the recent outbreaks in Batemans Bay, has piqued the interest of researchers.

A study published in the journal PLOS Neglected Tropical Diseases highlights the establishment of the bacteria responsible for Buruli ulcer in local possums near Batemans Bay. As possums are believed to be the primary reservoir for the bacteria, and mosquitoes serve as vital transmitters to humans, the findings indicate a potential increase in human cases similar to what has been observed in Victoria.

The bacteria discovered in Batemans Bay differs from those found in the more commonly infected areas of Victoria, such as Melbourne and Geelong. Batemans Bay has only reported two known cases of the ulcer in recent years, yet researchers are concerned this could signal expanding disease patterns due to favorable environmental conditions shared between coastal regions of Victoria and southern NSW.

Early diagnosis is crucial in managing this condition, as it can initially manifest as a minor insect bite but may lead to severe tissue damage if left untreated. One severe case from Batemans Bay resulted in the amputation of a 94-year-old man’s finger due to extensive ulceration.

While more questions arise regarding the sporadic nature of human cases appearing far apart, the study underscores a growing challenge for health authorities in NSW. The collaboration among infectious diseases specialists, pathologists, and researchers from various states reflects a dedicated effort to tackle this complex health issue.

In a hopeful outlook, increased awareness and research into Buruli ulcer may lead to better prevention strategies and treatment options in the future, potentially mitigating the impacts of this troubling disease. Efforts are underway to understand its spread better and protect communities at risk.
