Possibly the most comprehensive article to date on the origins of covid-19 - whether it arose naturally or possibly from lab/research activities, written by @dctrjack @CNET cnet.com/features/the-h…

Another article from back in Sep 2020 to read for more details about RaTG13 (closest related virus genome to SARS2), inconsistencies in how it was reported by the WIV, and an inaccessible pathogen database at the WIV. minervanett.no/alina-chan-cor…

💫article from May 2020 to understand how common lab accidents are, even at world class facilities, regardless of country.

".. 80% chance of an escape every 12.8 years. And that was in 2012, when such work was far less commonplace than it is now."

Worth listening for couple of minutes on new data concerning South African SARS2 variant 20H/501Y.V2 (B.1.351).

Seems that only first wave patients with severe covid, robust response to virus had neutralizing antibodies. But still unclear how lab results translate to real world.

Also, without being able to directly see the data, unclear whether the same patient serum samples could also neutralize the original SARS2 variant or other currently circulating variants.

@GISAID

As of Jan 15, 2021 (sequences deposited into @GISAID), these are the 14 countries where the South African 501Y.V2 variants have been detected.

Visualized on covidcg.org @CovidCg cumulative number of sequences in the B.1.351 lineage by country, over time (by week).

Very diplomatic take on the issue. I don't agree with everything in the thread, but agree that if this was a lab release it is a global problem - too many labs doing the type of work that can lead to accidental outbreaks.

On this point, we cannot let our fears of what will happen to science obstruct a thorough and transparent investigation into origins.

We cannot afford to not investigate lab origins because we are terrified of the consequences if found to be true.

Some scientists have dug themselves a hole by insisting on natural origins and ruling out or casting lab origins as conspiracy theories.

Those scientists do not represent the rest of scientific community, which for better or worst, have been quiet on this hyper-dangerous topic.

The US “has determined that the WIV has collaborated on publications and secret projects with China’s military. The WIV has engaged in classified research, including laboratory animal experiments, on behalf of the Chinese military since at least 2017.” state.gov/fact-sheet-act…

This was interesting. When did the pangolin experiments begin? Pre- or post-covid?

“The WIV became a focal point for international coronavirus research after the 2003 SARS outbreak and has since studied animals including mice, bats, and pangolins.”

@WHO

“Any credible inquiry into the origin of the virus must include interviews with these researchers and a full accounting of their previously unreported illness.”

Good timing. The @WHO origins investigation team is in China now.

1st time co-authoring an essay for a news site @WSJ Very thankful to @mattwridley for taking me under his wing and also to all of the wonderful experts @Peterfoodsafety @maciekboni @R_H_Ebright @FilippaLentzos @MilesPomper @DavidRelman @robertson_lab

@WHO

... who talked to us about this issue. Our piece is necessarily critical of @WHO investigation in terms of calling for actual steps to look into potential lab origins. But I found that all of the experts we talked to about this had very reasonable and persuasive viewpoints.

@mattwridley

@mattwridley and I wanted this piece to be a lot longer, in terms of clearly laying out the points for natural origins vs the points for lab origins in a balanced way, but a lot of that had to be reserved for another time. So please stay tuned for our next article together.

"The tiny flashes of dry wit and glimmering hope that surface in his letters and his conversations with consular officials tell them that he’s still there, somehow.
