The conference will take place December 9-10, 2019, at the Collège de France in Paris, France.


The debate on the origins of venereal syphilis is more than 5 centuries old, with some supporters of an American origin versus those advocating an older infection that emerged in the Old World. This question was the subject of a first international synthesis (ICEPID-1) in 1993: The origins of Syphilis in Europe: before or after 1493? New insights into the molecular biology of Treponemas, new paleopathological discoveries of skeletal treponematoses, and the reactivation of paleomicrobiological research on Treponemas, led us to propose a new synthesis on this issue as an ICEPID-6.

Six sessions will be organized during this meeting:

  • 1- History of syphilis - Theories and Men
  • 2- Modern Treponematosis: present clues for past clues?
  • 3- Treponema and bones: gummatous osteoperiostitis, from present to past
  • 4- On the molecular track of ancient syphilis
  • 5- Treponemal infections in pre-Columbian Americas
  • 6- Treponemal infections in Europe before 1493: what’s new?

Registration: Registration opens on August 1, 2019 via the conference website,, at which time registration fees will also be collected.
