The COVID-19 pandemic has spurred genomic surveillance of viruses on an unprecedented scale, as scientists around the world use genome sequencing to track the spread of new variants of the SARS-CoV-2 virus. The rapid accumulation of viral genome sequences presents new opportunities for tracing global and local transmission dynamics, but analyzing so much genomic data is challenging. There are now more than a million genome sequences for SARS-CoV-2. No one had anticipated that number when we started sequencing this virus, said Russ Corbett-Detig, assistant professor of biomolecular engineering at UC Santa Cruz.
