Did OMICRON variant of SARS-COV-2 come from an animal?


From The World’s Oldest Virus to The Newest Pandemic Variant w/ Erin Bromage, Bill Hanage, David Sanders & Sarah Otto

In this episode I set off on a quest to find the oldest endemic human virus–the one that’s been riding along with our species the longest.  The answer is harder to get than I’d anticipated, but along the way I learn about some ancient viruses, and how viruses shape our evolution as they evolve themselves.

I’ll also discuss where the omicron variant came from – including the possibility it jumped to another animal and back to humans. And I’ll get up to date on the latest worrisome variant – a sister of omicron called BA.2
