Selon l’OMS, Omicron semble bien se diffuser plus vite que le variant Delta, qui pour l’heure est encore responsable de l’essentiel des infections dans le monde. Cette diffusion plus rapide est constat\u00e9e non seulement en Afrique du sud, o\u00f9 Delta \u00e9tait moins pr\u00e9valent, mais \u00e9galement au Royaume Uni, o\u00f9 ce variant domine.
L’OMS ne sait pas pour le moment – faute de donn\u00e9es suffisantes – si ce taux de diffusion \u00e9lev\u00e9 dans des populations \u00e0 forte immunit\u00e9 vient du fait qu’Omicron \u00ab\u00a0\u00e9chappe \u00e0 l’immunit\u00e9, profite d’une transmissibilit\u00e9 plus \u00e9lev\u00e9e inh\u00e9rente ou s’il s’agit d’une combinaison des deux\u00a0\u00bb.<\/p>\n\n\n\n
Le variant Omicron du coronavirus semble se propager plus que le variant Delta, provoquer des sympt\u00f4mes moins s\u00e9v\u00e8res et rendre les vaccins moins efficaces, a indiqu\u00e9 l’OMS, qui a soulign\u00e9 que les donn\u00e9es restent tr\u00e8s parcellaires.
Omicron est d\u00e9sormais pr\u00e9sent dans 63 pays, a expliqu\u00e9 l’organisation dans une mise au point technique, qui confirme les d\u00e9clarations de ses responsables ces derniers jours.<\/p>\n","protected":false},"excerpt":{"rendered":"
