From WHO
"Buruli ulcer is caused by a germ that mainly affects the skin but which can also affect the bone. The causative organism is called Mycobacterium ulcerans, which although different, belongs to the same family of organisms that cause leprosy and tuberculosis.
Buruli ulcer has been reported in over 30 countries with tropical and subtropical climates but it may also occur in some countries where it has not yet been recognized. Limited knowledge of the disease, its focal distribution and the fact that it affects mainly poor rural communities contribute to low reporting of cases. Progress is being made now to develop tools for early diagnosis, to understand exactly how infection is transmitted and to improve treatment".
