1. I just read the new "report" by 13 infamous US based researchers, 2 from UK & Canada & 1 each from France, Belgium & Australia.
A 5 👁️- NATO collaboration ;)
Genetic evidence of susceptible wildlife in SC-2 positive samples at Huanan Seafood Market

Does it really take 15 NIH Grants to put lipstick on a raccoon dog?

4. A useful thread by @stevenemassey which exposes some of the technical flaws in this report, who concludes that this is a case study in the perils of making grandiose claims without having completed the analysis:

5. Looking at the Methods used
I get the impression that they repeatedly "filtered out", "excluded" and retained just enough data (based on possibly invalid data from China) to get the results they wanted to support their hypothesis!

6. Probably for the best
"This report is not intended for publication in a journal"
I doubt any respectable journal, even one run by dedicated natural origin proponents, would accept it anyway, hence its magical appearance on zenodo, the oft maligned home of citizen scientists

7. Hypocrisy Exposed!
Do you remember how @jbloom_lab was accused of racism and other nasty things by certain virologists, when he obtained Chinese data?
Well, now it turns out that these compromised virologists have done the same themselves!

After Van Kerkhove saw the zoonosis presentation on the data, she concluded that the data revealed nothing new!

9. Talk about stating the obvious!
"Other samples were dominated by animal genetic material linked to the stall where they were collected, such as cattle at a stall selling beef product, and fish in a sample collected on a fish packaging surface"

10. However, an important caveat
"Hence, the most abundant animal in the sequencing data of a particular sample is not necessarily the source of the virus in that sample"
(Page 9)

11. All fur coat and no knickers?
They could have just told the over eager reporters like @KatherineJWu and @benjmueller who bamboozled the public with zoonati propaganda puff pieces, the following:
"we cannot identify the intermediate animal host species from these data"

12. Partial Data used to spread propaganda!
"Our analysis is based on partial data, corresponding only to a subset of environmental samples from the market in which SARS-CoV-2 had been detected. Other sequencing data exist for some of these samples from Illumina NextSeq 550"

13. The Temptation of Saint Zoonati
"It would be tempting to pursue a correlational epidemiological analysis between the presence of animal genetic material & SARS-CoV-2 positivity using data from market samples that tested negative for the virus, when they become available"

14. Something is rotten in the state of Denmark
Based on filched, partial & unreliable data, filtered to support their crumbling hypothesis, these discredited charlatans claim "These arguments stand in stark contrast to the absence of evidence for any other SC-2 emergence route"

15. Timely press release from @BiosafetyNow
1 Data not made available for other researchers
2 Data provides no substantive new information about origins of SC-2
3 Researchers have documented track record of exaggerating findings & hiding major COIs

"We acknowledge these circumstances are unusual. We are proponents of open data sharing & ensuring that data from our analyses are broadly accessible in public repositories"
Yet, as @pricklyresearch found out, life ain't that easy!

23. Unanswered Questions
Where are the viral reads from each sample?
Why is there no SARS-CoV-2 column in the csv file?
What lineage (A or B) of SC2 was found in the Raccoon Dog sample?
Where is A20?
Does the data support a double spillover or not?

Gao et al. declared they use Kraken2 in their pre-print

25. Raccoon Dog Sub Species Question
Closest reported relative of the complete raccoon dog mitochondrial genome sequence was Nyctereutes procyonoides collected in the wild in East China, distinct from that of N. p. ussuriensis, the subspecies commonly raised in NE China for fur

26. A Puzzling Omission
Regardless of the exact sub species of Raccoon Dog, as @stevenemassey pointed out in his thread:
"none of the stalls with raccoon dog nucleic acid have a human SARS2 case linked to it (which puzzlingly they fail to mention)"

Money talks, but also distorts the truth..

Apart from the fact that CCDC refused to share market sample data for 3 years, despite repeated calls to do so @GISAID misleads us about the 2013 H7N9 bird flu outbreak

"In 2013, during the H7N9 avian influenza outbreak, they were credited in a Nature Editorial for "openness in the reporting and sharing of data [via GISAID]”
But, why was Michael Callahan "sent" to Nanjing then?

Some are euthanized, but..
