Characteristics of SARS CoV 2 variants of concern B.1.1.7, B.1.351 or P.1: data from seven EU/EEA countries, weeks 38/2020 to 10/2021
We compared 19,207 cases of SARS CoV 2 variant B.1.1.7/S gene target failure (SGTF) 436 B.1.351 and 352 P.1 to non variant cases reported by seven European countries. COVID 19 cases with these variants had significantly higher adjusted odds ratios for hospitalisation (B.1.1.7/SGTF: 1.7, 95% confidence interval (CI) 1.0 2.9; B.1.351: 3.6, 95% CI: 2.1 6.2; P.1: 2.6, 95% CI: 1.4 4.8) and B.1.1.7/SGTF and P.1 cases also for intensive care admission (B.1.1.7/SGTF: 2.3, 95% CI: 1.4 3.5; P.1: 2.2, 95% CI: 1.7 2.8)
