 The SARS-CoV-2 coronavirus emerged in December 2019 as a novel human pathogen causing
 a severe acute respiratory syndrome (COVID-19). The disease

 Genome sequencing of thousands of viral samples has helped researchers study mechanisms of 
 infection, transmission and response of the human immune system. 
 Since the beginning of SARS-CoV-2 circulation in humans, the viral genome has been accummulating
 mutations.  Compared to other RNA viruses its mutation rate is low, but enough variants are known 
 to determine how samples cluster into groups and how they are related (see COVID-19 transmission map).

 We at the

+        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 &quot;genomic contact tracing&quot;.
+        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 &quot;real time&quot;.
+        Our tool places genomes onto a comprehensive global phylogeny of more than 80,000
+        virus genomes in less than one second.
