Some thoughts on Omicron and COVID19 in the last week or so
Some recent Tweets and threads from me on Omicron and related topics
I am dismayed by the people, including leaders, who are treating #Omicron as "mild" & therefore not a big deal ignoring the unvaccinated & unboosted, long covid, at risk groups and that it is not "mild" for everyone, just on average has less severe effects to the vaccinated

It is not the flu.
It is not the common cold.
It is not mild.
It is not something to just let rip.
It is something we can and should keep fighting. https://t.co/any0vRZWwr

Tribute to EO Wilson
When I was a senior at @harvard in 1990 I started an "Environmental Issues" journal as part of activities leading to the 20th anniversary of Earth Day. I hoped to get EO Wilson to be our faculty sponsor. I phoned his office and arranged a meeting with him via his assistant 1/n https://t.co/0fyvH0ykky

Some thoughts on the CDC new mask guidance
See this thread
I am with @kprather88 here. Really vexed by what @CDCDirector and @CDCgov have done here. I mean, I get the general idea of trying to return to normal and encourage vaccination. But here are some thoughts for why I am still a bit vexed. https://t.co/tTzdFYoTqU

Compiling some of my Twitter comments about the evolution and origins of SarsCoV2/ COVID19
News Stories Quoted in
- UC Davis Aggie: Emerging SARS-CoV-2 variants raise concern for the future of the pandemic
- 9/15/2020. Newsweek. Fact-check: Does a New Study Give Evidence that the Coronavirus Was Made In a Lab?
- May 17, 2020. Newsweek: Scientists Shouldn't Rule Out Lab As Source of Coronavirus, New Study Says
- April 27, 2020. The controversial experiments and wuhan lab suspected of starting the coronavirus pandemic. Newsweek.
Relating to the lab vs natural origin theory of #SarsCOV2. I would like to call attention to the history of the anthrax attack investigation. Circumstantial evidence, that seemed so strong to so many people, was used to falsely accuse multiple people. https://t.co/olpDu8sKT9

Yes, as I told @newsweek it is theoretically possible that a Chinese lab accidentally released #SARSCoV2 https://t.co/90qFnFcKJc but preponderance of evidence so far supports all natural events and the evidence actually supporting "lab release" is shown in this pic #Covid19 pic.twitter.com/TyqAiFnQuf

Slides I have used for "Biodiversity and the Tree of Life" at @ucdavis
Many of the figures are from "Life v 11" by Hillis et al. which is the textbook we have been using for the class. I have been told in the past by the publishers that this was OK to do so I am assuming it is still OK. Hope there are not too many errors ... for some reason Lecture 10 will not upload - working on it

Collecting some of my comments about Sacramento County's poor response to COVID19
And then another rantThis does not seem like a good plan: "Sacramento County Announces New Mitigation Efforts COVID-19" https://t.co/5W3Dv4Lqr9 #COVID19 #Coronavirus - especially the plan to shift from containment to mitigation #Sacramento cc: @sacbee_news 1/n pic.twitter.com/dYUwEoUGb1— Jonathan Eisen (@phylogenomics) March 9, 2020
And this oneI think the Sacramento plan is problematic - if they are correct that it is time to ditch containment and move to mitigation then why is their mitigation plan among the weakest announced anywhere ? See https://t.co/mHnvLbdGGG https://t.co/mHnvLbdGGG— Jonathan Eisen (@phylogenomics) March 10, 2020
And then Placer and Yolo County came out with their somewhat more aggressive planBut couldn't you do quarantine for some people but not necessarily for health care workers?— Jonathan Eisen (@phylogenomics) March 10, 2020
And moreSo #Yolo and #Placer counties have announced that they are also stopping containment efforts. I still think this is a bad idea but at least compared to #Sacramento county these counties are at least pushing the mitigation strategy a bit more strongly. See https://t.co/pbtsOMbmGN https://t.co/ZZlO2NtmFX— Jonathan Eisen (@phylogenomics) March 10, 2020
And thisThe Sacramento County plan is a joke - 1) containment is still useful in some cases, they should not ditch it 2) their plan for mitigation (reducing community spread) is the most limited of any place I have seen in the country -see https://t.co/ZZlO2NtmFX— Jonathan Eisen (@phylogenomics) March 11, 2020

My posts about #UCDavis and #Covid19
February 26
Things blew up at @ucdavis with reports that the 1st community acquired case of COVID19 was at our hospital. I received an email about this that I eventually posted to Twitter (I waited to post until I saw others reporting this)
Tons of stories came out over the next few weeks about this and I will add some links to them. But eventually, attention went elsewhere as the 1st large clusters of cases that were detected in the US ended up being in other locations.Email I received earlier today from @ucdavis Medical Center leaders regarding the case of apparently community acquired #COVID19 in #Sacramento at #UCDavis hospital pic.twitter.com/q9qrJq5iWo— Jonathan Eisen (@phylogenomics) February 27, 2020

What's worse than not cancelling your conference during #COVID19? How about a #MANEL #YAMMM during #COVID19.
And alas, the meeting still on - April 2-4, 2020
As a side note, it is around the corner from where I used to work (it is in the same general area as where TIGR used to me).
And, alas, on top of the meeting apparently still being on, it is also what appears to be a MANEL - a meeting with a highly skewed gender balance of speakers. I say "what appears to be" since I just do not have time right now to do what I frequently do which is to look up people's personal websites to see how they describe themselves in terms of gender. So I am basing this entirely on names and appearance but it does not look like a good balance.
Not a good look Johns Hopkins and USUHS,
#1 - due to #COVID19 this conference should be cancelled
#2 - due to the apparently extreme gender skew for the speakers, this conference is one I would encourage people to not attend anyway.
