Fig. 1: Emergence and prevalence of the Delta and Kappa SARS-CoV-2 lineages.

From: Structural and biochemical rationale for enhanced spike protein fitness in delta and kappa SARS-CoV-2 variants

Fig. 1

a Delta (B.1.617.2), Kappa (B.1.617.1) and B.1.617.3 lineage frequency in India from January to July 2021. Deposited sequences were downloaded from the GISAID initiative. The 95% confidence interval is plotted as the lighter shaded border around each line. This figure panel was generated using the outbreak.info project3. b Daily confirmed COVID19 cases in India as curated by the outbreak.info project3. c SARS-CoV-2 amino acid sequence box plots for the wild-type (D614G) and B.1.617 sub-lineages. The abbreviations are NTD N-terminal domain, RBD receptor-binding domain, RBM receptor-binding motif. d Global prevalence for the Alpha, Beta, Gamma and Delta lineages of SARS-CoV-2 from January to July 2021. The sequence data were downloaded from the GISAID initiative and plotted as the percentage of the global prevalence for each week1,2.
