Abstract

The B.1.1.7 (Alpha) variant has been detected in Mumbai, India during February 2021. Subsequently, we retrieved 43 sequences from specimens of 51 COVID-19 cases from Mumbai. The sequence analysis revealed that the cases were mainly affected with Alpha variant which suggests its role in community transmission of SARS-CoV-2 in Mumbai, India.

Keywords: B.1.1.7; Community transmission; Mumbai; SARS-CoV-2; Variant of concern.

Phylogenetic tree of the SARS-CoV-2 sequences retrieved from Mumbai, Maharashtra: A neighbor joining tree was generated using a Tamura 3-paramter model with gamma distribution and a bootstrap replication of 1000 cycles. The sequences retrieved in this study are marked in boldfaced. The variants of concern, and the variants of interest are marked in different colors on branches; B.1.1.7 (light blue), B.1.525 (Crimson red), B.1.617.3 (orange), B.1.617.1 (brown), B.1.1.306 (pink color).
