Data Curation and SARS-CoV-2: population genomics of 2.5 million genomes

Covid-19 has become a global pandemic, and recently Arkansas has seen a dramatic increase in number of cases, mainly due to a new variant (“Delta”). Using a population genomics approach, we are in the third wave with the current Delta variant accounting for about 83% of the strains sequenced. This has been preceded by the Alpha variant, which peaked in March of this year (2021), and another less characterized variant (Janus), which peaked in September 2020. Each of these variants has become better adapted for infecting and spreading within the human population.
