Le Haut Conseil de la sant\u00e9 publique (HCSP) actualise, pour la saison vectorielle 2026, la liste des pays et r\u00e9gions consid\u00e9r\u00e9s a priori \u00e0 risque pour la transmission du virus West Nile (WNV) via les produits sanguins labiles, organes, tissus et cellules. Selon le Centre europ\u00e9en de pr\u00e9vention et de contr\u00f4le des maladies (ECDC), cette saison vectorielle s\u2019\u00e9tend en Europe du 1er juin au 30 novembre. Les donneurs ayant s\u00e9journ\u00e9 au moins une nuit dans les zones list\u00e9es font l\u2019objet d\u2019une contre-indication temporaire ou de mesures de d\u00e9pistage sp\u00e9cifiques li\u00e9es au WNV.<\/p>\n
L\u2019identification des pays et r\u00e9gions \u00e0 risque repose sur les crit\u00e8res d\u00e9finis dans l\u2019avis du HCSP du 16 juin 2021, \u00e0 partir des donn\u00e9es \u00e9pid\u00e9miologiques de l\u2019ECDC, de l\u2019Organisation mondiale de la sant\u00e9, du syst\u00e8me Arbonet des Centers for Disease Control and Prevention (CDC) am\u00e9ricains, de Sant\u00e9 publique France et des dispositifs locaux de surveillance. Par rapport \u00e0 la liste 2025, les principales \u00e9volutions g\u00e9ographiques concernent l\u2019Europe, avec l\u2019ajout de la Bavi\u00e8re pour l\u2019Allemagne et de la Cr\u00e8te pour la Gr\u00e8ce.<\/p>\n
Une autre \u00e9volution importante concerne la p\u00e9riode de s\u00e9lection des donneurs : alors que les listes pr\u00e9c\u00e9dentes ne s\u2019appliquaient que du 1er juin au 30 novembre, la s\u00e9lection est d\u00e9sormais \u00e9tendue \u00e0 toute l\u2019ann\u00e9e pour certains pays d\u2019Afrique du Nord, du Proche-Orient et du Moyen-Orient, ainsi que pour certains \u00c9tats des \u00c9tats-Unis. Cette extension tient compte d\u2019une circulation ininterrompue du virus dans ces zones, li\u00e9e \u00e0 l\u2019activit\u00e9 quasi continue des vecteurs. Ces ajustements ont des implications directes pour l\u2019organisation de la s\u00e9curit\u00e9 transfusionnelle et de la greffe en France, en particulier pour la gestion des contre-indications temporaires et des d\u00e9pistages additionnels des donneurs ayant voyag\u00e9 dans les zones concern\u00e9es.\u00a0(contenu r\u00e9sum\u00e9 par l’IA)\u200bLire la
