Discussion: This lineage is defined by 14 amino acid changes and three deletions, including six amino acid substitutions and two deletions in the spike protein: S:DeltaH69-V70, S:DeltaY144, S:N501Y, S:A570D, S:P681H, S:T716I, S:S982A, and S:D1118H and it has been related with some evolutionary advantages such as an increased transmissibility.

Result: The III wave was characterized by the appearance of the subset of mutations that distinguish the B.1.1.7 lineage such as H69_V70del, Y144del, N501Y, A570D, P681H, T716I, S982A, and D1118H.
