Result: Additionally, for the
T716I and
S982A variants, substitution frequencies increased over time (respectively, from 0.88% in December to 51.61% in February (OR: 10.59, 95% CI: 7.13-16.11, p < 0.0001) and from 0.88% in December to 50.97% in February (OR: 10.53, 95% CI: 6.97-15.72, p < 0.0001).
Result: Co-existence of DeltaH69V70,
DeltaY144,
P681H,
T716I,
S982A,
A570D,
N501Y, and
D1118H was the signature for the B.1.1.7 (20H/501Y.V1) variant.
Discussion: Our analysis shows that subsequently, three genetic lines of the SARS-CoV-2 molecular evolution have emerged, with the largest clade (Clade 1, lineages B.1.1.*) being the most diverse genetically, with a signif
