Omicron variant: What do we know and don't know with Michael Osterholm, PhD

Mutations happen with viruses all the time and the Omicron COVID-19 variant is the latest and is receiving a lot of media attention. Today is December 1, 2021, a very short time since the first cases were detected and the date of the first confirmed case in the US--so the questions are--What do we know and what do we not know? Joining me today to look at the Omicron variant B.1.1.529 is Michael Osterholm, PhD. Dr. Osterholm is the director of the Center for Infectious Disease Research and Policy (CIDRAP) at the University of Minnesota.
