Living with Buruli ulcer

A skin infection that starts with painless swelling and can become an open sore.

Understanding Buruli ulcer

Buruli ulcer is a skin infection caused by the bacterium Mycobacterium ulcerans.

It starts as painless, nodular swelling of the skin. This can lead to ulcers (open sores) with dying tissue.

Signs & symptoms

GARD describes these features:

  • Painless swelling of the skin (nodule)
  • Skin ulcers

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
