Les autorit\u00e9s sanitaires fran\u00e7aises signalent une premi\u00e8re infection humaine document\u00e9e par le virus Shamonda, un Orthobunyavirus transmis aux animaux par des moucherons piqueurs du genre Culico\u00efdes. Le cas concerne un patient pr\u00e9sentant une immunod\u00e9pression s\u00e9v\u00e8re, pris en charge aux Hospices civils de Lyon pour une pathologie grave et d\u00e9c\u00e9d\u00e9 d\u00e9but octobre 2026. Selon les investigations en cours, les complications c\u00e9r\u00e9brales observ\u00e9es chez ce patient seraient tr\u00e8s probablement li\u00e9es \u00e0 cette infection virale.<\/p>\n
Le virus Shamonda, d\u00e9tect\u00e9 pour la premi\u00e8re fois au Nigeria au milieu des ann\u00e9es 1960, circule de mani\u00e8re sporadique chez les bovins en Afrique de l\u2019Ouest, de l\u2019Est et australe, ainsi qu\u2019au Japon. \u00c0 l\u2019\u00e9t\u00e9 2026, il a \u00e9t\u00e9 identifi\u00e9 pour la premi\u00e8re fois en Europe, notamment en France, dans des exploitations bovines, avec des bovins consid\u00e9r\u00e9s comme h\u00f4tes principaux. Des cas sporadiques ont aussi \u00e9t\u00e9 observ\u00e9s chez de petits ruminants et des \u00e9quid\u00e9s en France durant le m\u00eame \u00e9t\u00e9. Jusqu\u2019alors, ce virus \u00e9tait consid\u00e9r\u00e9 comme non transmissible \u00e0 l\u2019\u00eatre humain.<\/p>\n
Pour le cas humain rapport\u00e9, l\u2019hypoth\u00e8se actuelle est celle d\u2019une contamination vectorielle par piq\u00fbre de moucheron Culico\u00efde dans l\u2019Est de la France, r\u00e9gion o\u00f9 la circulation du virus chez l\u2019animal a \u00e9t\u00e9 document\u00e9e au printemps\u2013\u00e9t\u00e9 2026. Les autorit\u00e9s pr\u00e9cisent qu\u2019il s\u2019agit d\u2019un cas exceptionnel survenu chez un patient fortement immunod\u00e9prim\u00e9 et qu\u2019au regard des connaissances disponibles, aucun risque sanitaire pour la population g\u00e9n\u00e9rale n\u2019est identifi\u00e9 \u00e0 ce jour.<\/p>\n
Les investigations cliniques, biologiques et \u00e9pid\u00e9miologiques se poursuivent dans une approche \u00ab Une seule sant\u00e9 \u00bb, associant les expertises en sant\u00e9 humaine, animale et environnementale. Les autorit\u00e9s sanitaires fran\u00e7aises ont notifi\u00e9 ce cas aux instances internationales comp\u00e9tentes, l\u2019Organisation mondiale de la Sant\u00e9 (OMS) et le Centre europ\u00e9en de pr\u00e9vention et de contr\u00f4le des maladies (ECDC). Les incertitudes portent notamment sur les conditions exactes de transmission \u00e0 l\u2019\u00eatre humain et sur la port\u00e9e \u00e9ventuelle de ce cas isol\u00e9, en particulier dans des contextes d\u2019immunod\u00e9pression s\u00e9v\u00e8re.\u00a0(contenu r\u00e9sum\u00e9 par l’IA)\u200bLire la Suite<\/a>\u200b<\/p>","protected":false},"excerpt":{"rendered":" Les autorit\u00e9s sanitaires fran\u00e7aises signalent une premi\u00e8re infection humaine document\u00e9e par le virus Shamonda, un Orthobunyavirus transmis aux animaux par des moucherons piqueurs du genre Culico\u00efdes.
