         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.
