YAWS

Written by

A non-venereal disease caused by Treponema pertenue and characterised by skin and bone lesions similar to those seen in secondary syphilis. The disease is caused by a spirochaete morphologically, immunologically and serologically identical to Treponema pallidum, the cause of syphilis. Yaws is clinically very similar to another nonvenereal treponematose, pinta, caused by T. carateum and found in South America and the Caribbean.
