Phylogenetic reconstruction using a maximum likelihood tree inferred with 815 time-calibrated complete genomes including 324 viral genomes from Puerto Rico and 491 contextual genomes from the United States and the Americas to provide a regional backdrop. Node structure supported by 1000 bootstrap replicates. Tree topology sections shaded in red represent clusters of viral genomes from Puerto Rico. Each cluster from Puerto Rico is labeled with cluster number C.x and Delta sub-lineage PANGO assignment [AY.x].
