Sure, but don't they have a vast network of contact tracing? Presumably if a bunch of cases showed up that weren't connected to any other cases because of the lockdowns then that would be a really good indication of where the animal reservoir was located. But they haven't found the animal reservoir yet either, even with all of the lockdowns.

If by 'animal reservoir' you mean the intermediary pangolin, or something similar, this 'reservoir' could be as small as 1 animal if it was a spontaneous mutation. Where do you get the idea that there must be a large population of such animals roaming around?

[Teever]

Wasn't the intermediate pangolin idea also discredited as exceedingly improbable relatively early in the pandemic?

[MichaelZuo]

Can you link to a source?

[Teever]

No, I can't, that's why I'm asking a question about it.

[MichaelZuo]

As far as I can tell authoritative source has ever made an on-the-record comment along those lines. But then again it's impossible to prove a negative.
