Frambesia tropica
Treatment involves a single dose of penicillin G. It is rare for the disease to return.
If treated in its early stages, yaws can be cured. Skin lesions may take several months to heal.
By its late stage, yaws may have already caused damage to the skin and bones. It may not be fully reversible, even with treatment.
Yaws may damage the skin and bones, affecting the appearance and ability to move. It can also cause deformities of the legs, nose, palate, and upper jaw.
Contact your health care provider if you or your child has sores on the skin or bone that don't go away, and you have stayed in tropical areas where yaws is known to occur.
