Phylogenetic analysis of SARS-CoV-2 genomic sequences collected in the Chiaravalle patients. Multilineage phylogenetic tree reconstructed using 913 SARS-CoV-2 sequences downloaded from GISAID database. The SARS-CoV-2 consensus genomes of the 60 Chiaravalle patients are indicated with a red dot. Inclusion of all 60 consensus genomes led to a cluster of genomes around the founder genome. The reliability of the phylogenetic clustering was evaluated using bootstrap analysis with 1000 replicates.
