How long does it take for syphilis to show in body?

Syphilis symptoms typically appear within 10 to 90 days after exposure to the bacteria, with an average of about three weeks. The first sign is usually a painless sore, known as a chancre, which occurs at the site of infection. If left untreated, the infection can progress through various stages, each with different symptoms. Regular testing and early treatment are essential for effective management.
