/Do all babies born with congenital syphilis have signs or symptoms?

No. It is possible that a baby with congenital syphilis won’t have any symptoms at birth. But without treatment, the baby may develop serious problems. Usually, these health problems develop in the first few weeks after birth, but they can also happen years later.

Babies who do not get treatment and develop symptoms later on can die from the infection. They may also be developmentally delayed or have seizures.
