On the Origin of Syphilis and Contemporary Views of Disease Dynamics

Despite syphilis being a disease of antiquity, diagnosis and treatment remains problematic globally due to a complex biologic pathogen/host relationship and the spread of the disease embedded in human behavior. First documented as anindependent disease in 1495, the origin of syphilis has been ambiguous for over500 years.

In the past century, there have been several approaches to investigate the origins of syphilis, but without definitive outcome. A viable syphilis control option became available in the 20th century with the discovery of penicillin, leading to cost effective and safer treatment compared to prior use of mercury- and arsenic-containing compounds. However, despite the availability of antibiotics that can successfully treat syphilis, the disease waxes and wanes at various times and among certain social groups or settings, due in part to risky sexual behavior, a complex clinical presentation (multiple clinical stages including a latent stage where there are no clinical signs), diagnostic challenges and spontaneous healing or unnoticed lesions resulting in failure to seek clinical care or sexual partners not being referred for treatment.   Read more>>>>>>>>>>>>>>>
