A cluster of BA.3

In effect, Omicron is still largely in the majority (99.6% of sequencing in week 7) with the majority of identified sequences belonging to the BA.1 sub-variant. But its BA.2 sub-variant is gaining ground and teaches us Public Health France : 15.4% in week 6, 25% in week 7… 38% in week 8 (preliminary data). It would even have become the majority in the New Aquitaine region.

In addition, Public Health France announces that 17 cases of BA.3, variant very rare in France, were identified on February 28th. According to SPF, it would be the same cluster.

Finally, regarding the variant Deltacronwho “is subject to increased monitoring by Santé Publique France and the CNR Respiratory infections virus”, 18 sequences have been identified, ie 8 more than last week after the announcement of its discovery on French territory. This recombinant would have been discovered in several regions since the beginning of January, which would attest to a “traffic level at low levels for several weeks”.
