Having carefully read this, I& #39;m not sure I would have green-lit this piece to run.

I& #39;m not sure the words "mainly from Europe" conveys enough accuracy. I& #39;m not sure a layman is going to interpret this in a way that is substantively true.

Let me explain /1 https://twitter.com/nytimes/status/1248071228520304641">https://twitter.com/nytimes/s...
The data that the researchers are using comes from here.

Here& #39;s">https://nextstrain.org/ncov/glob... a map of phylogeny (the evolutionary history) of the virus

Note that all "paths" of this virus lead back to China. That is not in any way under dispute by anyone. /2
There are a couple of key mutations here. There is this one that I believe was the first US case that we saw in Seattle. It came directly from China.

Cases from this strain ended up in Washington, California, a few in NY. /3
Then we& #39;ve got this strain which branched in Belgium. The top section of red represents many of the cases from NY (and some in WI and CA) and came through France /4
But there are a ton of missing pieces because we can only map what we sequence and places with better sequencing capabilities are going to show up with clusters.

For example: Where is Iran on this map? Well, we don& #39;t have a Iranian samples sequenced so we have to infer. /5
We know that one of the early NY sequences came from someone with a travel history to Iran, but it seems like maybe that branch died off. /6 https://twitter.com/trvrb/status/1239427201499426816">https://twitter.com/trvrb/sta...
Anyway, that& #39;s what I know. I worry a lot about what people will think is true and the conclusions they draw about things they just barely understand (I& #39;m included in that group).

I& #39;m not sure a evolutionary deep-dive on COVID genetics is something I& #39;d put "Breaking News" on. /7
It sounds like something that maybe, as a news org, you decide is a little more complex than a "Breaking News" headline would warrant and maybe the details are best left to the experts and readers who care enough to search it out /8
