If you’re pregnant, it’s important to get treated for syphilis because you could pass the disease to your fetus or newborn. Again, your doctor will give you penicillin. If you’re allergic to it, your doctor will put you through a special process so you can take the antibiotic.
If you do spread the STD to your fetus or newborn, it can be very serious and lead to:
Stillbirth (the baby is born dead)
Birth defects
Infant death
Cataracts
Deafness
Seizures
