Quick Answer

Syphilis progresses through four stages: primary (painless chancre, ~3 weeks), secondary (rash, fever, flu-like symptoms), latent (silent, years to decades), and tertiary (neurologic, cardiovascular damage, 10-30 years later). Each stage is curable with penicillin, but late-stage damage is irreversible.

  • Primary: painless sore (chancre) at infection site, heals on its own
  • Secondary: diffuse rash including palms/soles, fever, lymphadenopathy
  • Latent: completely asymptomatic for years to decades
  • Tertiary: neurosyphilis, cardiovascular damage, gummas

Context Most Pages Skip

Syphilis is called "the great imitator" because its symptoms at each stage mimic other diseases. The painless chancre, the non-itchy rash, the decades of silence — all of them fool patients and clinicians.

The Curability Window

Syphilis is curable with penicillin at any stage. The tragedy is that late-stage damage is irreversible even after cure. This is why screening is essential.
