I'm not ruling out some secret US-funded research into a SARS-COV2 type virus that escaped in Wuhan. Difficult to rule it out. But it requires a secret research program not recorded in that lab because the records don't show any such sequence used as well as lapses in biosecurity, Admittedly lapses in biosecurity are very possible, the US has outlawed such research because its own labs were shown to have repeated lapses, and the UK equally finds it h
According to Chinse sources (people working at the lab) Xi ordered the first day of the virus escape that all probes of CoV-19 and all lab journal immediately get destroyed. So THH you are on the safe side. AS the direct evidence has gone. But it will be impossible to find a zoonotic source as such is simply impossible to exist. Unluckily the few species that can catch corona never made it into the lab or even close to it.
Just to remember you that the event happened almost 6 weeks before the official Chinese announcement. Now confirmed by virus data from Italy! (And your secrete service..)
