Concerns over coronavirus variants addressed during Congressional briefing

Concerns over coronavirus variants addressed during Congressional briefing: As the U.S. continues to grapple with the pandemic, there are growing concerns about the risks posed by variants of SARS-CoV-2 - the coronavirus that causes COVID-19. Recent data have shown that at least one SARS-CoV-2 variant is more transmissible than the original, and there are questions as to whether any variants could be more deadly. The main way to detect emerging variants is to perform widespread genome sequencing, but the sequencing infrastructure in the U.S. is struggling to keep up with demand.
