We screened 2,95,000 complete genomes of CoV-2, reported worldwide in
GISAID (Dec, 2019-Dec, 2020), for variants in S, N, M, and E proteins. A
large number of mutations were detected in structural proteins of CoV-2
(Table 1). However, the patterns of mutation are still unknown. This
wide range of variations projects toward the number of strains variation
of virus present worldwide.
