Labs across U.S. test for COVID Omicron variant

Labs across the United States are testing to see where Omicron COVID-19 variant will emerge first. The U.S. is sequencing 80,000 positive PCR tests per week to test for variants and learn how fast the variant is spreading — and how infectious it is. 

About 2,000 of those sequences occur at the Pandemic Response Lab in New York City, which "CBS Mornings" lead national correspondent David Begnaud visited.

The lab is "sequencing the COVID genome of thousands of positive COVID samples," said Jon Laurent, head of research and development at the lab.
