Épidémiologie des leishmanioses autochtones en France métropolitaine et d’outre-mer

Abstract

Leishmania infantum is the only species occurring in metropolitan France; located in the Mediterranean part of the country, it is responsible for a highly enzootic canine disease, while the human endemicity is low, with about 23 cases yearly reported to the National Reference Centre of Leishmaniases, mainly visceral forms. In French Guyana, five Leishmania species occur in the Amazonian forest, of which L. guyanensis is the predominant species, and L. braziliensis is responsible for the most critical forms. The most frequent clinical feature is cutaneous leishmaniasis, with a mean annual incidence reaching 2 p. 1000, with some inter-annual fluctuations. In Martinique Island, recent studies have confirmed the presence of an ancestral Leishmania species, responsible for small cutaneous lesions, of mild evolution; the life cycle of this species remains unknown. In Guadeloupe Island, a few autochthonous visceral leishmaniasis cases have been reported, needing a prospective study.
