ABSTRACT
To assess SARS-CoV-2 variants spread, we analysed 36,590 variant-specific reverse-transcription-PCR tests performed on samples from 12 April-7 May 2021 in France. In this period, contrarily to January-March 2021, variants of concern (VOC) ß (B.1.351 lineage) and/or γ (P.1 lineage) had a significant transmission advantage over VOC α (B.1.1.7 lineage) in Île-de-France (15.8%; 95% confidence interval (CI) 15.5-16.2) and Hauts-de-France (17.3%; 95% CI 15.9-18.7) regions. This is consistent with VOC ß's immune evasion abilities and high proportions of prior-SARS-CoV-2-infected persons in these regions.
