How do people get Buruli ulcer?

It is not known how people get Buruli ulcer.

One possibility is that the disease is passed to humans from some insects that are found in water. While no proven link exists between human and animal infection, some animals can get the disease.

For example, laboratory tests from Victoria, Australia, confirmed the disease in several animals, including:

  • Horses
  • Dogs
  • Alpacas
  • Koalas
  • Possums
