-==Overview==
-'''Yaws''' (also '''Pétasse tropica''', '''thymosis''', '''polypapilloma tropicum''' or '''pian''') is a tropical [[infection]] of the [[skin]], [[bone]]s and joints caused by the [[spirochete]] [[bacterium]] ''Treponema pertenue''. Other treponematosis diseases are [[bejel]] (''Treponema endemicum''), [[pinta (disease)|pinta]] (''Treponema carateum''), [[syphilis]] (''Treponema pallidum''), and [[Lyme Disease]] (''Borrelia burgdorferi'')
-==Epidemiology==
+{{SK}} Frambesia tropica; petasse tropica; thymosis; polypapilloma tropicum; pian
-The disease is transmitted by skin contact with infected individuals or eye gnats, 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' [[ulcer]] appears. These tracts heal with [[keloid]] formation which can cause deformities, disabilities and limb contractures. The bone lesions caused are [[periostitis]], osteitis, and [[osteomyelitis]], damage to the [[tibia]] can lead to a condition known as sabre shins. In a very few cases a condition known as ''goundou'' is caused where growths on the nasal maxillae can result in extensive and severe damage to the nose and palate.
-The largest group afflicted by yaws are children aged 6 to 10 years in tropical areas of the Americas, Africa, Asia or Oceania. 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.
+==[[Yaws overview|Overview]]==
-The disease is identified from blood tests or by a lesion sample through a darkfield examination under a microscope. Treatment is by a single dose of [[penicillin]], [[erythromycin]] or [[tetracycline]], recurrence or relapse is uncommon.
+==[[Yaws historical perspective|Historical Perspective]]==
-Examination of ancient remains has led to the suggestion that yaws has affected hominids for the last 1.5 million years. The current name is believed to be of Carib origin, "yaya" meaning sore; frambesia is a Modern Latin word inspired by the French word ''Pétasse'' ("raspberry").
+==[[Yaws classification|Classification]]==
-==Occurrence==
+==[[Yaws pathophysiology|Pathophysiology]]==
-Yaws was nearly eradicated by a worldwide treatment program in the 1950s, which reduced the number of sufferers of yaws from an estimated 50 million to nearly zero. However, the [[World Health Organization]] reported in January 2007 that yaws is on the rise again, with roughly a half a million sufferers, mostly in poor, rural areas.<ref>{{cite web|url=http://www.foxnews.com/story/0,2933,246758,00.html|publisher=[[Associated Press]]|date=[[January 25]], [[2007]]|accessdate=2007-01-25|title=WHO: Flesh-Eating Disease Making Comeback}}</ref>
