Not sure if I'm reading this document right, but it looks like there are many things we should be investigating to see if SARS-CoV-2 has natural or lab origins. nonproliferation.org/op-49-a-guide-…
Let's apply the Investigation Methodology shown in Fig 2 to the current pandemic. A natural origin has not been confirmed; no animal samples from the market or Hubei province have tested positive despite a scattering of pangolin CoV papers from Guangdong and GuangXi province. Image
Despite the lack of evidence for a natural origin, many experts have come out as saying that it is clear that SARS2 has completely natural origins and that lab-based scenarios are implausible. The independent investigation of lab is led by long time funder+collaborator of WIV.
The past ~10 months have been spent investigating natural origins (blue left panel of Fig 2) with zero evidence of natural spillover; shouldn't there be some international pressure to get moving on the lab origins investigation (green right panel of Fig 2)?

There is speculation that US funded collaborations with the Wuhan Institute of Virology to keep an eye on virus research there.

The problem is that, when a pandemic happened, the middleman did not produce intelligence but also actively suppressed the lab leak theory.
When the SARS-CoV-2 sequence was released in Jan 2020, EcoHealth could've said
1⃣They planned to put furin cleavage sites in SARS-like viruses
2⃣In 2013, the Wuhan lab discovered a new lineage of SARS-like viruses that the covid virus belongs to
3⃣Work was done at low biosafety
Instead we had to go through 5 years of the lab leak hypothesis being painted as a racist, anti-science conspiracy theory and a ton of misinformation from EcoHealth about the work being done in Wuhan.

No punches pulled piece on #OriginOfCovid by @ianbirrell

"The pandemic revealed the arrogant and contemptuous behaviour of leading scientific figures, aided by prominent academic journals, patsy journalists and weak politicians."
unherd.com/2025/01/chinas…
@ianbirrell I suggest one correction @ianbirrell please replace 'despite' with 'because of':

WHO "hired Sir Jeremy Farrar, despite the former Wellcome Trust boss’s exposure as a central player in... branding any suggestions Covid could have come from a laboratory as conspiracy theory."
@ianbirrell On Feb 19, 2020, the authors of Proximal Origin realized that Jeremy Farrar - who had convened them and led their efforts - had signed the Lancet letter by Daszak condemning all lab #OriginOfCovid as conspiracy theories. Image

5 years ago, the authors of Proximal Origin wondered where the pandemic virus had been transmitting *intensely* so that it gained a furin cleavage site and passed it on.

One said, "No way the selection could occur in the market. Too low a density of mammals." #OriginOfCovid Image
Until today, there has been no reported sign of intense transmission of the virus in animals prior to the detected outbreak in Wuhan.

Investigators, including one Proximal Origin author, searched fur farms in China - no sign of any SARS-like virus.

On the other hand, a 2018 research proposal surfaced, showing Wuhan and US scientists with a plan to insert novel furin cleavage sites into novel SARS-like viruses.

"5% chance that H5N1 starts a sustained pandemic in humans in the next year. 50% chance that H5N1 starts a sustained pandemic in humans in the next twenty years..."

I invite @slatestarcodex to estimate the chances of a lab-based flu pandemic by 2025!
astralcodexten.com/p/h5n1-much-mo…
@slatestarcodex For consideration, only 4 projects have been flagged by NIH for HHS review since 2017.

One project, funded till 2020, proposed creating ferret transmissible H5N1.

One project, proposed in 2024, was not funded by NIH so no info was made public.
aspr.hhs.gov/S3/Pages/Resea…Image
@slatestarcodex In addition, under the new US gov policy on research that enhances the pandemic potential of pathogens, it will be the funding recipient (not the funder) who is responsible for flagging their own federally funded projects for review.

Peter Daszak, who partnered with the Wuhan lab that likely caused the pandemic and is being debarred by HHS, continues to chair @NASEM_Health's forum on microbial threats.

Daszak's forum is hosting @theNASEM workshop on the future emergence of pathogens.
nationalacademies.org/event/43921_01…
@NASEM_Health @theNASEM The event disclaimer and website make no mention of Daszak's involvement in this event or any conflicts of interest. Image
@NASEM_Health @theNASEM This echoes Daszak's behind-the-scenes coordination of the infamous letter in @TheLancet casting lab #OriginOfCovid as a conspiracy theory without disclosing his conflicts of interest.

In 2020, leading virologists deceived a @nytimes journalist, resulting in NYT dropping the lab leak hypothesis.

Years later, these virologists continue to deny their perfidy while attacking experts like @sigridbratlie who call out their deception.
telegraph.co.uk/us/news/2024/0…
@nytimes @sigridbratlie At the @USFHealth Covid meeting, natural #OriginOfCovid proponents exalted one of these virologists.

Thankfully @ewinsberg read out the slack messages of these virologists which completely contrasted with their public stance.
@nytimes @sigridbratlie @USFHealth @ewinsberg Some consider the lies of leading virologists as indirect evidence for a lab #OriginOfCovid e.g. see the end of this anonymous analysis on youtube.

Why are some smart virologists making so many claims they should know are false?
