What are the effects? If left untreated, syphilis can eventually cause damage to the brain, nerves, eyes, heart, blood vessels, liver, bones, and joints. In extreme cases it can cause difficulty coordinating muscle movements, paralysis, numbness, gradual blindness, mental illness, and even death. If you have syphilis and are pregnant, it can cause serious birth defects and stillbirth.
The latent stage of syphilis begins when all of the symptoms you had earlier disappear. If you do not receive treatment, you can continue to have syphilis in your body for years without any signs or symptoms. Most people with untreated syphilis do not develop late stage syphilis. syphilis infection is called an âearlyâ case if a patient has been infected for a year or less, such as during the primary or secondary stages of syphilis. People who have âearlyâ syphilis infections can more easily spread the infection to their sex partners.
