Latent yaws

Description

Latent yaws is defined as yaws with no clinical signs and only serological evidence of infection (reactive treponemal and non-treponemal tests). Infectious relapses may occur in latent cases for up to 5 and, rarely, 10 years. The total duration of infectivity for an untreated yaws patient, including relapses, is thought to be about 12-18 months.

Inclusions
