Context Most Pages Skip

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

Key Facts

Syphilis is fully curable with penicillin at any stage. The challenge is making the diagnosis before the damage is done. Screening is recommended for all pregnant women, sexually active men who have sex with men, and anyone with multiple partners.
