In pregnancy, untreated early syphilis is responsible for 1 in 4 stillbirths and 14% of neonatal (newborn) deaths. About 4% to 15% of pregnant women in Africa test positive for syphilis. Interventions to more effectively screen pregnant women for syphilis and prevent mother-to-child transmission of the disease could prevent an estimated 492 000 stillbirths per year in Africa alone.
