Endemic treponematoses are a group of chronic bacterial infections caused by treponemes. These infections are:
- Yaws, also known as framboesia or pian, caused by Treponema pallidum subsp. Pertenue;
- Endemic syphilis, also known as bejel, caused by T. pallidum subs. Endemicum;
- Pinta caused by T carateum.
All these infections often affect the skin and present skin lesions.
Bejel occurs principally in the Sahel region of Africa and Arabian Peninsula and pinta is restricted only to Latin America.
