Syphilis is a serious sexually transmitted infection (STI) that does not go away without treatment. If syphilis is not treated, it can harm the brain, heart, and other organs, and lead to blindness, paralysis, or brain-related changes years later. Syphilis can also be passed from a pregnant person to their baby, risking the baby's health or life.
