[Endemic syphillis in Upper Volta. A peculiar aspect of the epidemiological profile].

A seroimmunological survey was realised in Upper Volta using an indirect immunofluorescence technique. It showed that endemic syphilis also known as bejel is not exclusively encountered in Sahelian regions. So, in Kora village which is located in a savannah area prevalence was around 10.3%. The disease particularly affects males. Congenital syphilis is certainly exceptional for first cases of serological treponematosis were only detected after 5 years. Endemic syphilis distribution in microfocuses in the village area underlines that promiscuity acts as a contributing factor for contamination.
