Figures

(A) Line graph showing the mutation and case prevalence over time in India. The novel variant "B.1.617.2" has a sharp rise in April and May 2021 (green line) in the upper half of the figure coinciding with the increasing cases as represented by the second peak in April and May 2021 in the lower half of the figure. (B) Graphical representation of the prevalence of common variants of SARS-CoV-2 over the past 60 days (April and May 2021) in India with “B.1.617.2” being the most dominant variant (48%). (Fig. 1A and 1B source: Outbreak.info; Available online: https://outbreak.info/).

(A) Bubble plot comparing the population, actual number of COVID-19 cases and the genome sequencing data (per 1000 cases) deposited in the GISAID database for major countries around the globe. (B) Map comparing the genome sequencing data (per 1000 cases) deposited in the GISAID database across the globe. Developed countries such as United States, United Kingdom and Australia (marked in blue) have the maximum contribution to genomic surveillance while developing nations in Asia and Africa lag well behind (marked in light green). (C) Plot showing the relative contribution of various countries to genomic surveillance, prevalence of disease and the median days to deposition to the GISAID database. India (yellow line) is in the lower part of the curve (far left) in terms of genomic sequencing reflecting poor genomic surveillance however, is ranked second just behind the US (blue line) in terms of absolute number of cases.
