Aureomycin has been shown to be effective in the treatment of infections caused by certain bacteria, viruses, rickettsiae and spirochaetes.

There have been no reports concerning the use of aureomycin in the treatment of yaws.
In January 1950, at the Hôpital Général, Port-au-Prince, Haiti, we commenced a clinical study to determine the effectiveness of aureomycin as a therapeutic agent in yaws.

Three had primary lesions only; eight had both primary and secondary lesions; one had a primary lesion, secondary lesions and plantar lesions;
