My belief is simply that there is no such evidence.
Reasonably convincing evidence, to me, would be:
- genetic precursor virus particles which have died and no longer exist - they are extinct, or,
- dated blood samples with immunological evidence of infection, sufficient that it isn’t just tampered/false positives. There’s no reason to expect this would have been collected.
i.e. if you haven’t collected it by 2019, there is never going to be any evidence.
This also answers your sibling commenter: it’s not in China’s interest to publicise any such search, when the odds of discovering anything (even if there were earlier infections) are vanishingly low.
