we now have 13 #HCoV19 genomes from Washington State. All 12 of the genomes from community cases have grouped into an emerging outbreak clade.
This figure shows the genetic relationships among these viruses, where all the WA viruses are closely related. Given this shared ancestry pattern, it looks like the large majority of current cases in WA derive from a single introduction event.

Hi all, we submitted the #COVID-19 genome sequence from the viral strain linked to the #GrandPrincess cruise ship off coast of San Francisco to #GISAID. Phylogenetic analysis shows that it clusters with the outbreak clade circulating in Washington State. @UCSF #coronavirus

so why can't we know WHO was the "introduction event"???

it would be important to know....and would explain a lot....

Tucker is having an excelling opening, discussing the COVID-19 virus threat, here in the US.

Talking about how we’re past the point of containing, the stress on our medical system, on and on.

VERY good segment....if I can find a link, I’ll post.

They know that there’s many thousands of cases. Dr Seigal talking about the testing mess...not just the kits...but, the absurd hold ups in health departments. And, shortage of tests...especially for those who have symptoms or feel they mat have been exposed. Not enough tests, for these people, across the country.
