Because COVID origins is suddenly topical again (hmmm because it is an election year?) I thought I’d share again the article @LawrenceGostin and I wrote on the topic.
Happy to share @LawrenceGostin and my new (free access) article on COVID-19 origins in @NEJM, which includes a timeline for investigating the origins and other related events. The Origins of Covid-19 — Why It Matters (and Why It Doesn’t) | NEJM

@NateSilver538 Still doesn’t matter— the majority of people could believe COVID came from aliens and it wouldn’t change the fact that there is little scientific support for that view. The important thing is to understand what actually happened—it is a scientific issue not a popularity contest.

Are you kidding me, @nytopinion? I can give you at least 25 reasons why SARS-CoV-2 did NOT come from a lab, and in fact I have done so. You really shouldn’t platform conspiracists. Let’s start with this summary:

@NateSilver538 @K_G_Andersen Hi Nate, because it is 2023, why not check out this great paper by @LawrenceGostin and me about what we actually know about the origin of COVID. People who are upset that the scientific evidence is not supporting their preferred theory are just trying to change the subject.

Asserting it was a lab leak doesn’t make it true. There is no new evidence presented here and the science clearly, overwhelmingly points to a natural emergence at Wuhan market. There are steps we can take to prevent that from happening again and I’d be delighted to discuss them.
The @COVIDSelect Committee confirmed in their final report today that the most likely origin of the COVID-19 pandemic was a lab leak from gain-of-function research in Wuhan, China. Despite Dr. Fauci’s repeated attempts to downplay accountability, the NIH’s funding and oversight

@thor_benson I spoke to gg about anthrax in 2008/9 (the person the FBI determined was responsible for the anthrax letter attacks died by suicide, I am a biosecurity expert and worked at USAMRIID )… he was pushing his false narrative the whole time. Was grateful it was a live segment.

Kudos to @jocelynkaiser for covering this (and the scientists who filed the complaint!). Ebright and Nickels have been heaping abuse and misogyny on others for years. I hope that more articles will follow to profile Ebright who has had outsized influence on policy.
A dozen #COVID19 scientists have filed a formal complaint with Rutgers University alleging that two faculty members violated the university’s policies by posting “provably false” comments that are often defamatory and that could incite harm against them.

In 2008 Glenn Greenwald @ggreenwald kept trying to get me to falsely say that the US has an offensive biological weapons program. He has an anti-US agenda divorced from facts and it’s irresponsible for news outlets to have him on about this serious topic.

Since I published on the origin of COVID-19 describing why a natural emergence was more likely (and how it relates to the GOF research debates), the scientific evidence has only gotten more voluminous. It's still current and written for non-scientists, give it a free read.
New: The Contested Origin of SARS-CoV-2, published in Survival @SurvivalEditors a publication of @IISS_org. This topic has been full of charged rhetoric. My aim is to provide clarity, to focus on preventing future pandemics from the likeliest pathway.

In case this is my last tweet before twitter shuts down. just wanted to say this was my favorite moment, when my cat Sloopy was honored by @giantcat9. I am so grateful for the people on here who spread joy, share accurate information, and who tweet pictures of cats.

The US does not have an offensive biological weapons program. Full stop. On the other hand, Russia has been recently & credibly accused of violating the Biological Weapons Convention, a bad habit they have had since 1975 when it came into force. Excellent reporting @Justin_Ling.
Yesterday I wrote on a fast-moving conspiracy theory that seeks to rationalize Russia's invasion of Ukraine, and marry it with a tangle of QAnon paranoia. Let's look at how this theory came to be — and how it's still being promoted by Moscow.

Perhaps @drdrew missed this info before booking @DrLiMengYAN1, but her claims have been thoroughly debunked. She uses sciencey sounding words but strung together they make no sense and her conclusions are wrong. Nonetheless, you (and @TuckerCarlson) give her a platform.

Excellent 🧵describing the new results supporting zoonotic origin of COVID. A side note from me— this breathtaking detail is a tremendous leap forward in attributing ANY biological incident, and should be viewed as a deterrent to misuse. Just extraordinary detective work.
Two years ago, we demonstrated that the SARS-CoV-2 pandemic likely began at the Huanan Market via zoonosis resulting from the wildlife trade. Many unanswered questions remained about the animals themselves. Some answers, out today in @CellCellPress.

@NateSilver538 The lab leakers weren’t silenced (by the previous administration, by reporters like Josh Rogin, by many of the LL, by outlets like Bulletin of atomic scientists, by you) and furthermore evidence suggests the LL were _incorrect_.

Thank you @beyerstein for capturing why @Ayjchan and @mattwridley can keep the lab leak theory alive in spite of mounting contrary evidence. What is most upsetting, really, are the One Health issues that won't get discussed while they line their pockets.

This is an excellent piece by @Justin_Ling. It describes some of the major problems with the 'lab leak' theory (still wonder about the origin of that term. which hasn't been often used to describe lab accidents before)

@NateSilver538 A reminder that the evidence we know about strongly supports a natural origin and any intelligence would need to square w that context. It’s not saying it couldn’t happen, but that serious people should be skeptical and wanting more information.

In addition to vaccination, improvements to ventilation can limit COVID spread to protect children and keep them in school (IN-PERSON!). 1. Schools should bring in as much outdoor air as HVAC system will safely allow and upgrade filtration @polsiewski

@NateSilver538 An alternative way to read @KatherineJWu ‘s excellent article (which quotes some terrific influenza researchers struggling to figure out whether flu is likely to be bad this year and why there is so much uncertainty) is that you should just get your flu shot.

@NateSilver538 I used to wonder— how could people believe in the four humours and bleeding etc for HUNDREDS of years even though none of it was true? I now realize it’s because people had strong instincts on that theory because thinking our health was determined by bile is pretty legible.

Happy to share my new piece @lawfareblog on why the evidence points to a natural emergence— not a lab leak— for SARS-CoV-2. Also about why we need better regulated markets internationally & how much important stuff we have left to discover in virology.

Thank you so much to my anonymous letter writers, my super supportive chair @MarshaKarp1, and great colleagues at @JHSPH_CHS @JohnsHopkinsEHE. Pretty amazing to leave the bench for a 'non-traditional path' to work on biosecurity with DA Henderson and Tara O'Toole and get _here_!.
Congratulations @ggronvall on being promoted to professor! Gronvall, PhD, '00, an immunologist, has written extensively about synthetic biology, preparations for bioterrorism, and the contested origin of SARS-CoV-2. @JHSPH_CHS @JohnsHopkinsSPH .⤵️.

@toxicologist12 @NaturesPoisons People always asked me (background in biosecurity) “omg are we all going to die?” And I would say yes, because… well, we are all going to die at some point. (I’m not invited places but hopefully someday!).

COVID-19 did not come from a lab. Targeting scientists who are trying to understand and monitor future disease threats just leaves us all less prepared to deal with them.
I wrote about how EcoHealth Alliance is fighting back against their scapegoating and ongoing targeting by the lab leak-pushing GOP-led House Select Subcommittee on the Coronavirus Pandemic. Featuring comments from @angie_rasmussen.

There's been a lot of talk about "smoking guns" or "alarm bells" re: COVID origins. Well, for me, that feeling happened on page 98 of the WHO investigation report.
"There are lots of pieces to still fill in, but this report [from @MichaelWorobey and colleagues] ties a lot of the pieces together that say, 'There is a really credible story for an animal origin of SARS-CoV-2,'" says @JHSPH_CHS senior scholar @GGronvall.

It's great testimony @K_G_Andersen, but I am sorry this sorry spectacle is occurring, and that a Congressional committee is treating US scientists this way. So many people should be feeling ashamed for their behavior that led up to this moment, if shame were in their capacity.

@j_g_allen What’s the big deal? My kid’s school is back to masks because of the high volume of positive tests. While community spread is high, it seems reasonable to take simple steps so that school is a safer place to be and so they can continue to enjoy the fun end of year activities.

My coauthor @Michelle_Rozo and I examined 3 possible origin explanations that led to a 1950's strain getting a second chance to spread around the world: a deliberate release, a vaccine trial or challenge, or a laboratory accident.

Failures in testing, continued. This was a serious problem in the early months of COVID-19, in mpox, and now with H5N1. There will be future disease emergencies-- we have to do better. The diagnostic testing ecosystem is crucial, it is critical infrastructure.
🚨Scoop: A behind-the-scenes look at the bird flu outbreak shows the US hasn't fixed a key failing from covid -- getting people tests. Only 45 people tested over the past 3 months. "We're flying blind," said @JenniferNuzzo. Mine @KFFHealthNews .

We (@LaneWarmbrod @rachelmwest @ndconnell) have undertaken a scientific review of a pre-print by Yan et al. which presents a theory about the origin of SARS-CoV-2 but offers contradictory and inaccurate information that does not support their argument.

This is a disgrace, @COVIDSelect. Lab leakers were hardly suppressed and furthermore, the evidence points away from that hypothesis. Can we not further suppress talking about illegal animal sales and One Health? Because the conditions that led to COVID-19 will happen again.
"Proximal Origins" played a pivotal role in wrongly suppressing the lab leak hypothesis. Americans deserve to know why this happened, who was involved, and how we can prevent the suppression of scientific discourse during a future pandemic.

Programs like the media fellowship at @aaas should be expanded. Scientists should be funded to counter this garbage. The people behind orgs pushing lies _should_ be ashamed but aren't. This problem isn't going away soon, we need more creative solutions.

This is such an honor for me, having long admired the important work the foundation has done to make improvements to int’l biosafety in Beth Griffin’s memory— looking forward to the ABSA conference and the lecture!.
Congrats to Sr Scholar @ggronvall on being named by @ABSAOffice as the recipient of this year's Griffin Lecture Award! The E. R. Griffin Lecture Series Award recognizes accomplishments that contribute to the awareness of biological +occupational safety.
