Zebra Awareness Ribbons for Rare Diseases

What is Yaws?
Yaws is an infectious tropical disease caused by the spirochete bacterium known as Treponema pertenue. The disease presents in three stages of which the first and second are easily treated. The third, however, may involve complex changes to the bones in many parts of the body. The first stage is characterized by the appearance of small, painless bumps on the skin that group together and grow until they resemble a strawberry. The skin may break open, forming an ulcer. The second stage presents with a crispy, crunchy rash that may cover arms, legs, buttocks and/or face. If the bottoms of the feet are involved, walking is painful and the stage is known as "Crab Yaws." Stage 3 Yaws involves the long bones, joints, and/or skin. Yaws is very common in tropical areas of the world but it is not known in the United States. It is not a sexually transmitted disease. It occurs in children younger than 15 years of age.
