Flesh-Eating Ulcer Cases Rise on NSW South Coast: A Growing Health Concern
Health authorities in New South Wales are urging vigilance after a sixth case of Buruli ulcer, a rare and debilitating flesh-eating infection, was detected in the Batemans Bay-Moruya area. This marks a significant increase in cases acquired locally since 2021, with three reported in the last year alone.
What is Buruli Ulcer?
Buruli ulcer is a bacterial infection caused by Mycobacterium ulcerans. The bacteria produces a toxin that damages skin and soft tissues. If left untreated, the resulting ulcer can expand, leading to significant skin and muscle damage. The disease is typically spread to humans through mosquito bites.

Batemans Bay Identified as a New Hotspot
While Buruli ulcer is traditionally found in Victoria, Far North Queensland, and the Northern Territory, recent research has pinpointed Batemans Bay as a potential new hotspot. A study published in PLOS Neglected Tropical Diseases identified the area as being at risk, prompting increased monitoring and research.
Early Detection: A Game Changer
Scientists are now focusing on early detection methods. Researchers have discovered that the bacterium responsible for Buruli ulcer can be found in possum faeces in areas where the disease is emerging in humans. This suggests possums act as a reservoir for the bacteria, with mosquitoes serving as the vector for transmission.
By testing possum faeces, researchers can potentially identify areas at risk before human cases appear. Genomic analysis allows for precise tracking of the bacteria, linking infections back to their environmental source. This proactive approach could be crucial in controlling the spread of the disease.

Protecting Yourself: Prevention is Key
Southern NSW Local Health District physician Anton Forsyth emphasizes the importance of prevention. Residents and visitors are advised to minimize mosquito bites by wearing loose, long-sleeved, light-colored clothing and using mosquito repellent containing DEET or Picaridin.
Anyone developing an ulcer that isn’t healing should seek medical attention promptly. Buruli ulcer is treatable with antibiotics, but requires a specific course of treatment different from typical ulcer medications.
Frequently Asked Questions
- What are the symptoms of Buruli ulcer?
- The disease typically presents as an ulcer, often on the legs, ankles, or arms, that doesn’t heal.
- How is Buruli ulcer spread?
- It is most commonly spread to humans through the bites of infected mosquitoes.
- Is Buruli ulcer common in NSW?
- Buruli ulcer is rare in NSW, but a small number of cases have been detected on the south coast, particularly around Batemans Bay.
- What should I do if I suspect I have Buruli ulcer?
- See a doctor immediately. Early diagnosis and treatment are crucial.
Stay informed and protect yourself. If you live in or visit the Batemans Bay-Moruya area, be vigilant for symptoms and take preventative measures against mosquito bites.
