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) β (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 β’s immune evasion abilities and high proportions of prior-SARS-CoV-2-infected persons in these regions.
