title: General considerations on endemic treponematosis in the rural Sahel region of Upper Volta.
abstract: A sero-immunological survey conducted by indirect immunofluorescence technique has made it possible to determine accurately the prevalence and distribution of treponematoses in the Sahel rural region of Upper Volta. The number of carriers of antitreponemal antibodies varies from one place to another, but is particularly high in a nomad community, where prevalence attains 84.2%. The magnitude of endemic foci can also be expressed in terms of maximal titer and geometric mean of antibody titers. The seropositive values increase as a function of age, but sex is not a significant factor as regards prevalence, which would appear to depend essentially on the way of life, habits and promiscuity.
