Yaws most often affects children in tropical regions of Africa, Asia, and Latin America. It spreads through direct contact with the skin of an infected person.
A single, berry-like sore on the skin is the first sign of yaws. Without treatment, sores begin to spread. Yaws may eventually cause disfigurement and disability.
The condition can be treated in its early stages with a single dose of penicillin.
