Abstract

The emerging N501Y mutation in severe acute respiratory syndrome coronavirus 2, which becomes prevalent in the UK rapidly, is one of the major challenges of COVID-19 control. To explore the transmission advantage, we estimate that the N501Y substitution increases the infectivity by 52% (95% confidence interval: 46, 58) in terms of the reproduction number.

Keywords: B.1.1.7 lineage; COVID-19; mutation; reproduction number; statistical modelling; transmission advantage.

The daily number of COVID-19 cases (panel A), the reconstructed reproduction number (Rt, panel B) and proportion of the Y on the 501th codon of the S protein (panel C). Panel A shows the daily number of COVID-19 time series in the UK. Panel B shows the estimated reproduction numbers of Y (in orange) and N (in purple). The dots are the estimates, and bars are the 95% confidence intervals. Panel C shows the observed (dots) and fitted (curve) proportion of the Y on the 501th codon of the S protein
