other info:
Yaws is a tropical infection of the skin, bones and joints caused by the spirochete bacterium Treponema pertenue.

The disease is transmitted by skin contact with infected individuals, the spirochete entering through an existing cut or similar damage. Within ninety days (but usually less than a month) of infection a painless but distinctive ‘mother yaw’ ulcerous papule appears on the skin at the point of entry, it is often described as raspberry-like and is 10-50 mm in size.
The largest group afflicted by Yaws are children aged 6 to 10 years in the Caribbean Islands, Latin America, West Africa, India, Oceania or Southeast Asia. There were World Health Organization funded campaigns against yaws from 1954 to 1963 which greatly reduced the incidence of the disease, although more recently numbers have risen again.
