Learn to identify the symptoms of latent and tertiary stage syphilis. The latent stage begins when the symptoms of stages 1 and 2 disappear. The syphilis bacteria is still in the body, but there are no longer any signs or symptoms of the disease. This stage can last for years.

Tertiary stage syphilis may not show itself until 10 to 40 years after the initial infection.
