/Is syphilis dangerous?

Yes. Syphilis is very dangerous. In addition to infecting other people, untreated syphilis can cause brain damage, heart disease, neurological problems and other long-term health problems. Once internal damage is done from syphilis it cannot be repaired, even after being cured from the syphilis itself.

Pregnant women can also pass syphilis to their unborn babies. This is known as congenital syphilis.
