Syphilis symptoms occur in three stages, but people infected with syphilis may not show any symptoms for years. However, they are at risk of suffering health complications later if they do not receive treatment. Even if a person has no symptoms they can still pass and spread the disease.
If caught early Syphilis can be cured with antibiotics, but not without the possibility of it causing serious damage. The use of a condom does not guarantee protection from getting or spreading syphilis.
