Syphilis is a bacterial infection spread through open sores during sex. It can also be spread from a mother to her baby during pregnancy. There are three stages to a syphilis infection.

Symptoms include:

  • Primary stage: a painless, raised firm bump or bumps that go away without treatment
  • Secondary stage: a rash may develop over the palms of hands and soles of the feet, flu-like aches, hair loss
  • Late stage: muscle and coordination issues, mental disorders, organ damage

Treatment in the primary stage will cure the disease. A blood test is necessary to test for syphilis.
