All sorts of uncontested facts. Just one: the Chinese have sampled tens of thousands of animals to find Sars-Cov-2 and have drawn a blank. But with Sars-Cov-1 the zoonotic transmission animal was found within 4 months.  And then there were multiple confirmations. Nothing proves the lab leak – but the weight of evidence points very heavily in that direction.
- Wade gives 4 months. But the source may be contested. Let’s take a more conservative estimate: WHO was reporting the link to civets in January 2004. And Sars-Cov-1 started in February 2003 – so on this timeline about 11 months. So far for Sars-Cov-2 at least 15 months and no animal source identified. At least we can say that the longer this goes on with no intermediary species found the more unlikely is the zoonotic theory.
