https://twitter.com/jbloom_lab/status/1651428639676960769Most inaccurate to me is table 1. It relies on an arbitrary 20% cutoff of all chordates to dismiss many samples with wildlife DNA/RNA. I've put it below, with a corrected version on the right without this cutoff. Multiple viral positive samples had raccoon dog DNA. (2/7)
https://twitter.com/mattwridley/status/1590967171517394947RaTG13 is not the most similar virus to SARS-CoV-2 at the whole genome level: BANAL-20-52 is. (96.8% for BANAL-52 and 96.1% for RaTG13) At the whole genome level, RaTG13 and SARS-CoV-2 diverged several decades ago.
https://twitter.com/BallouxFrancois/status/1583165259799412737The authors focus on cut sites of BsaI and BsmIB. Why these two REs? The simple answer is there is no good reason- they were just cherry-picked as the “most unusual”. Here's a plot of just a few RE cut sites possibilities across coronavirus genomes (SARS-CoV-2 at top)
https://twitter.com/mbeisen/status/1583067586589208576Problem #2: the idea here is that readers will read the paper, read the reviews, read the response, and reach a conclusion. I think that rarely works in practice except for field experts- we've been trying this on the rest of the internet for decades without a lot of success

Turns out the patient had a fever due to a tooth infection on Dec 8, while his COVID symptoms started Dec 16. Today in NYT, a WHO team member agrees with that assessment.

Most agencies also assess with low confidence that SARS-CoV-2 probably was not genetically engineered; however, two agencies believe there was not sufficient evidence to make an assessment either way"
