    Hi Vincent and Nels,
    thanks for your great podcast.

    I have a question regarding your estimates of coronavirus mutation rate. You sort of downgraded that on the podcast (rightfully so, considering how media react to those). but while the gives an 24.75 subs/year for ncov, it also contains dataset for other viruses. So for flu they have 3.53e-3/site/year, which matches well with the literature I think. However, when comparing apples to apples it is 8e-4 for ncov, or roughly 4 times less the mutation rate of the influenza virus.

    While this is definitely smaller, but still pretty much comparable, don’t you think?

    thanks again for your great podcast, it’s an essential part of my ‘shelter in place’ routine these days,

    What a pleasant conversation about the science of CoV-2 and beyond. The measured and knowledgeable voice of Dr. Elde through the welcome nudges of Vincent provides a welcome window into our current context and future challenge opportunities.
    Thank you for this conversation that welcomes laypersons into it. You both are so well-spoken. Impressive!
    Thank you, Nels, for your depth of knowledge, experience, and research in this important SCIENCE!

  3. noob here, divergence number in nextstrain means?
    i.e.: “Divergence: 7.962”

    • When tree is changed from time to divergence it gets higher from left to right.

    Could it be possible to have a transcript for those who can’t hear please?

  5. Hi, this article about TWiEVO 53: Virus evolution by land
    and by sea and by CoV, part II is very useful and inspirational.
    That is why I want to help me to leave you a way to get rid of herpes:
    Great success with this site!
