Symptoms: Yaws causes bumps to appear on the skin. Usually starting as one bump and escalating to multiple skin lesions. The skin will crust over and then shed, and what remains resembles a raspberry or strawberry-like texture. The original bump is referred to as the "mother yaw." All preceding bumps are referred to as "daughter yaws," and are not spotted for 6-16 weeks of the mother yaw's appearance. Nearly all cases are witnessed in children under 15 years of age, with the peak of infection occurring at ages 6 to 10. Yaws occurs in four stages. The primary stage being the start of the "mother yaw," the secondary stage marked by presence of "daughter yaws," the third stage known as the latent stage is when most areas of the skin clear up, and the final stage is the tertiary stage, in which yaws can destroy parts of the skin, bones, or joints.Cause: Yaws is caused by a bacterium called Treponema pertenue.
Body Systems Affected: Systems affected include the Integumentary System, as well as the Skeletal System.
Locations: Yaws is most commonly found in humid and tropical areas in Asia, Africa, South and Central Americas, as well as many Pacific islands.

Mother yaws and daughter yaws? Any treatments recommended, as this is caused by bacteria?
This is a dangerous disease where it starts as a bump and progresively escalades into skin lessions.The bacterium affects your integumentary and skeletal system.
