         a tool for identifying the relationships among a user's newly sequenced viral genomes
         and all known SARS-CoV-2 virus genomes. UShER identifies relationships between viral
         genomes by adding them to an existing phylogenetic tree of similar sequences that
         visually depicts the evolutionary relationships among the genome sequences.
         This approach empowers "genomic contact tracing".
         That is, UShER tells you whether virus genomes are closely related and therefore
         possibly from the same source, or if they are distantly related and the infections
         come from distinct sources.
         When newly sequenced virus genomes are added to a comprehensive tree of previously
         sequenced genomes, contact tracers are often able to determine where in the world
         those genomes came from.
         UShER is the only available method that can do this in "real time".
         Our tool places genomes onto a comprehensive global phylogeny of more than 80,000
         virus genomes in less than one second.
