SARS-CoV-2 S-protein allele dynamics

India (Updated on: 2026-04-02)

Sweep dynamic plots displaying country-wise frequencies of amino acid changes in the spike protein of SARS-CoV-2 over time. Amino acid changes are defined via an ancestral reconstruction on a phylogenetic tree and frequencies are calculated and evaluated as described in Klingen et al. (2018). Changes detected as significantly on the rise are shown in colour.
A * indicates the significant rise in frequency.

Lineage frequency per mutation
