[Natural pathogenicity for man of an antigenic variant of Soldado virus from Morocco (author's transl)].

Pathogenicity of Soldado virus was clearly established in the past for seabirds but remained questionable for man. In a scientist, repeatedly bitten by Ornithodoros (A.) maritimus larvae at Essaouira (Morocco), the association of fever of unknown origin and of neutralizing antibody against an antigenic variant of Soldado virus isolated from the same place, lead to the conclusion that this virus may act as a pathogen for man. Epidemiological implications of such an observation are briefly discussed.
