Syphilis Reinfection: Can You Get Syphilis Twice?
Nexus Laboratories health information team • Updated 8 October 2026
Yes. Successful syphilis treatment does not make you immune. A later exposure can cause another infection, so prevention and appropriate screening remain important.
A positive antibody test is not enough
Treponemal antibody tests may remain reactive after treatment. Reinfection is not diagnosed simply by seeing another positive home screen. A clinician compares your history, symptoms and appropriate laboratory results.
How follow-up helps
Keep a record of the treatment date, regimen and follow-up titres. Share any new exposure or symptoms with your clinic rather than waiting for the next routine visit. A change in results may need assessment for reinfection or an inadequate treatment response.
Reducing the chance of another infection
Partner assessment and treatment, completing the advised period without sexual contact and using barriers correctly help reduce risk. Discuss screening frequency with a clinician according to your circumstances. Avoid blaming partners or assuming an antibody result establishes when infection occurred.
Frequently asked question
Do I need follow-up if I have already been cured?
Follow the clinic's monitoring plan and discuss new exposures. Previous treatment does not exclude reinfection.

Use this guide to prepare questions for a healthcare professional. Bring your exposure dates, symptoms, test results and any treatment records. Ask what the result means, whether you need another test and how follow-up will be arranged.
This is general health information, not an individual diagnosis. Seek urgent care for new vision, hearing or neurological problems; contact your antenatal team promptly about a possible exposure during pregnancy.
