late latent syphilis

The United Kingdom uses a cut-off of two years for early and late latent syphilis.

Late latent syphilis is asymptomatic, and not as contagious as early latent syphilis.

Late latent syphilis does not have any specific symptoms, and it is not as contagious (meaning that it does not spread as easily) as early latent syphilis.

If the cerebro-spinal fluid (CSF) is examined in cases of late latent syphilis, a proportion of cases will be shown to have abnormalities indicative of neurosyphilis when there are no overt signs or symptoms of this complication.
