Neurological problems

It’s possible for syphilis to infect the nervous system during any stage of the infection - this is typically referred to as neurosyphilis and can cause a number of problems, such as [2]:

  • Stroke
  • Meningitis
  • Visual problems
  • Dementia
  • Cardiovascular problems


The genital sores caused by syphilis sometimes bleed making it easier for HIV to be transmitted during sexual contact. It’s estimated that there is a two to five-fold increased risk of contracting HIV if exposed to HIV while syphilis is present [3].

Congenital syphilis

Congenital syphilis is a form of syphilis that occurs when a mother with syphilis passes it on to her child during pregnancy - this is in fact one of the most preventable causes of stillbirth globally [4].
