Frequently asked questions
Why is syphilis called the great imitator?
Its symptoms can look like many other conditions and often come and go, so it can be missed. A simple blood test is the reliable way to diagnose it.
Can syphilis be cured?
Yes. Antibiotics cure syphilis, and treatment is most effective in the early stages. Any damage already done in late-stage disease may not be reversible, so early testing matters.
