Quick Answer
Syphilis is both acute and chronic, depending on the stage. It starts as an acute infection with a painless sore, then a temporary rash, and if untreated it settles into a long, silent chronic phase that can last years or decades. Treatment with penicillin cures it at any stage, so the chronic phase is not inevitable.
- Syphilis starts acutely with a painless sore and a temporary rash.
- If untreated, it becomes chronic, sitting silent in a latent phase.
- A minority of untreated cases reach late stages years or decades later.
- Chronic diarrhea is not a typical syphilis symptom; other causes are far more likely.
- 'Congestive syphilis' is not a real diagnosis; congenital and cardiovascular syphilis are.
- Benzathine penicillin cures syphilis at every stage, though late disease needs longer treatment.

'Acute' and 'chronic' describe timing, not severity, and syphilis refuses to fit neatly into either box. The cause is Treponema pallidum, a corkscrew-shaped bacterium that divides unusually slowly - roughly every 30 hours rather than every 20 minutes like many common bacteria. That slow tempo, plus the organism's ability to hide in places the immune system patrols poorly, such as the central nervous system and the eyes, explains why symptoms arrive in waves separated by long quiet stretches. Clinicians therefore describe syphilis by stage rather than by acute or chronic, because each stage has its own symptoms, transmission risk, and treatment length.
