“Wuhan lab workers were sick in November 2019, intelligence suggests”
Also, the WIV was more than 2 km from the market; the grandparent is probably thinking of a different, closer lab. The market was definitely the first big super-spreader event, but not necessarily the site of introduction into humans; the earliest cases show much less clear geographic distribution.
There's no conclusive evidence for any origin of SARS-CoV-2 yet. The ODNI report clearly leans against a research-related origin, but no one except the LA Times's "business columnist" is claiming that they "debunked" anything.
YMMV but to me the spike protein encoding on the original covid strains was just a little too close for comfort to fall into the random mutation category for my armchair opinion. I would have expected to see a non-human variant of the spike protein if it was a natural occurrence.
Either way, it is doubtful to me that we will ever know for sure.
The bat virus they were doing gain-of-function research on at the Wuhan Lab came from miles away.
