What are the effects if syphilis is left untreated?

Answer:

Syphylis is divided into four stages:

  • Primary
  • Secondary
  • Latent
  • Tertiary (late)

An untreated infected person may infect others during the first 2 stages (1-2 years).

Even though untreated syphilis is not contagious in the late stage serious complications can occur:

  • blindness
  • mental disorders
  • neurological problems
  • serious heart abnormalities
  • death
