This time, the Omicron variant has well and truly taken over. Initially detected in southern Africa, this mutation has spread in a few weeks to the four corners of the world, gradually taking the lead over the Delta variant, hitherto the majority. To the point of crushing it completely. According to the latest bulletin from Public Health France, dated January 13, 89% of the positive tests recorded during the first week of 2022 could correspond to Omicron.
To reach this conclusion, the laboratories carry out a screening of the positive PCR tests. If they contain neither the E484K mutation (Beta) nor the L452R mutation (Delta), then the Omicron variant, which also affects triple vaccinated, is suspected. Nearly nine out of ten positive cases are in this situation, according to the health agency.
A meteoric progression for Omicron, which represented 75% of contaminations during the last bulletin of Public Health France, published last week, and had become the majority in the country on December 31, 2021.
All regions of mainland France are affected by its emergence, in particular Île-de-France, where this strain represents 95% of cases. Martinique (84%), Guyana (88%) and Mayotte (99%) are not left out. These indicators “illustrate the continuation of the rapid replacement of Delta by Omicron throughout the national territory”, indicates Public Health France.
