Implementation of an oral R 1 C Significant progress has been made in the past 5 years with chemotherapy is supported by recent evidence of its the demonstration of the efficacy of rifampicin plus bactericidal activity in vivo [7, 8] and by several clinical streptomycin (R 1 S) Chemotherapy [2].

Here, we report a pilot study involving 30 implementation has dramatically improved healing while patients with Buruli ulcer disease treated using an oral reducing the frequency of relapses [3]. However, combination of rifampicin and clarithromycin over an 8- streptomycin is an inject able drug, and the lack of an week period. All patients were successfully healed, and no efficacious oral treatment remains one of the main obstacles to decentralizing care at local level.
