Syphilis is a sexually-transmitted disease causing open sores, tumours and eventually cardiovascular problems and insanity.

The disease can also be passed from mother to unborn child. Children born with syphilis can display deformities, seizures and developmental issues. If untreated, the child can develop symptoms of late-stage syphilis including damage to the bones, teeth, ears and brain.
