It is very unlikely that the initial superspreader event of a pandemic would be in a wet market that would be the one place for an animal spillover.

And when you look at the documented lab release of SARS-CoV-1, it killed the researcher's mother. If a lab leak happened, we would expect it to hit the people closest to the researchers at the lab who were infected, and the places they visited. Hitting only the wet market isn't very likely.

The outbreak looks like a wet market spillover. The fact that it happened in the same city as WIV is an unusual coincidence, but if the virus developed in rural Hubei, it was likely it would spillover in Wuhan.

Zoonotic spillover is not a spontaneous 0->100 event, there should be a trail of intermediate hosts and adjacent infections that there is zero evidence of.

thats not representative of sarscov2. People in the same household could fail to spread infection.

> Hitting only the wet market isn't very likely.

It didnt. There were early cases outside of the wet market.

> unusual coincidence

A novel coronavirus appearing outside a coronavirus gain-of-function research lab is not a coincidence. Id sooner believe it was a sleight of hand to cover for a terrorist attack.

I think perhaps there is a correlation with population density as well. Wuhan is fairly dense, and the wet market that is subject to speculation is located in the most densely populated district of wuhan.

Is it possible that the animals at the wet market itself was the source? Sure. But it seems sort of coincidental to me it is also the most dense area of the city; could’ve already been spreading and this location just happened to be where a major outbreak occurred from density factors alone.
