Still doesn’t make sense… based on the mutation rate, this would have to be someone infected a year or two ago…

- slenk 5y agoI would like to know how you came to the conclusion that this person would have been infected so long - I'd love to see the math. I'm more inclined to believe the experts in this instance.
- sjg007 5y agoIt's pretty simple. You can estimate the genetic mutation rate from the phylogenetic tree since we've been sampling the distribution of Sars-Cov2 genomes since the original Wuhan strain. If that rate is constant and if the variants all mutate at the same speed that gives you a rough timeline. Omicron has 50 mutations that are not related to other known variants. Delta has 13. We've seen delta for about 1 year right? So it's not a big leap to roughly double that estimate for Omicron.
