Syphilis is a sexually transmitted disease caused by the spirochetal bacterium Treponema pallidum subspecies pallidum. The route of transmission of syphilis is almost always through sexual contact, although there are examples of congenital syphilis via transmission from mother to child in utero.
The signs and symptoms of syphilis are numerous; before the advent of serological testing, precise diagnosis was very difficult. In fact, the disease was dubbed the “Great Imitator” because it was often confused with other diseases, particularly in its tertiary stage.
Syphilis can generally be treated with antibiotics, including penicillin. One of the oldest and still the most effective method is an intramuscular injection of benzathine penicillin.[citation needed] If left untreated, syphilis can damage the heart, aorta, brain, eyes, and bones. In some cases these effects can be fatal. In 1998, the complete genetic sequence of T. pallidum was published, which may aid understanding of the pathogenesis of syphilis.[1][2]
The name “syphilis” was coined by the Italian physician and poet Girolamo Fracastoro in his epic noted poem, written in Latin, entitled Syphilis sive morbus gallicus (Latin for “Syphilis or The French Disease”) in 1530. The protagonist of the poem is a shepherd named Syphilus (perhaps a variant spelling of Sipylus, a character in Ovid’s Metamorphoses). Syphilus is presented as the first man to contract the disease, sent by the god Apollo as punishment for the defiance that Syphilus and his followers had shown him. From this character Fracastoro derived a new name for the disease, which he also used in his medical text De Contagionibus (“On Contagious Diseases”).[3]
Until that time, as Fracastoro notes, syphilis had been called the “French disease” in Italy and Germany, and the “Italian disease” in France. In addition, the Dutch called it the “Spanish disease”, the Russians called it the “Polish disease”, the Turks called it the “Christian disease” or “Frank disease” (frengi) and the Tahitians called it the “British disease”. These ‘national’ names are due to the disease often being present among invading armies or sea crews, due to the high incidence of unprotected sexual contact with prostitutes. It was also called “Great pox” in the 16th century to distinguish it from smallpox. In its early stages, the Great pox produced a rash similar to smallpox (also known as variola). However, the name is misleading, as smallpox was a far more deadly disease. The terms “Lues” (or Lues venerea, Latin for “venereal plague”) and “Cupid’s disease” have also been used to refer to syphilis. In Scotland, Syphilis was referred to as the Grandgore. The ulcers suffered by British soldiers in Portugal were termed “The Black Lion”.[4]
There have been three theories on the origin of syphilis which formed an ongoing debate in anthropological and historical fields.
The pre-Columbian theory holds that syphilis symptoms are described by Hippocrates in Classical Greece in its venereal/tertiary form. There are other suspected syphilis and findings for pre-contact Europe, including at a 13–14th century Augustinian friary in the northeastern English port of Kingston upon Hull. This city’s maritime history is thought to have been a key factor in the transmission of syphilis.[5] Carbon dated skeletons of monks who lived in the friary showed bone lesions typical of venereal syphilis. Skeletons in pre-Columbus Pompeii and Metaponto in Italy demonstrating signs of congenital syphilis have also been found,[6][7] although the interpretation of the evidence has been disputed.[8]
The Columbian Exchange theory holds that syphilis was a New World disease brought back by Columbus and Martin Alonso Pinzon[citation needed]. Supporters of the Columbian theory find syphilis lesions on pre-contact Native Americans and cite documentary evidence linking crewmen of Columbus’s voyages to the Naples outbreak of 1494.[9] A recent study of the genes of venereal syphilis and related bacteria has supported this theory, by locating an intermediate disease between yaws and syphilis in Guyana, South America.[10][11]
