Hmm. So no real scientific work done on this, just some 'general' reports in the media? Smells like some sort of a cover-up. We wouldn't want China blamed for all trouble world-wide, would we? Or Trump's America, even worse!
If you take a virus carried by animals and synthesise it with a virus carried by humans you do not have to alter its DNA; the virus will mutate naturally. You can start testing it in human cell cultures before you decide to try to alter its structure, depending on what you want to do with it. At this early stage of the proceedings, depending on what original viruses were used, the new combined virus may only have a limited degree of effect upon either humans or animals. But it is likely to be very infectious to humans, and if at this point it 'escapes' and infects the human population, there will be no sign of DNA 'tampering', because nobody has tampered with it yet.
So my bet is that this was a lab experiment that 'escaped' long before it got anywhere near the stage of being lethal to everyone who got it.
There still are top scientists saying that there are markers of lab grade cornavirus, ie in the animal kingdom it takes ever so long to mutate, in lab conditions these mutated markers show up more ie they can tell if its been fast tracked alond by its dna.
however on this morning i was bored they interviewed the woman scientific advisor ben sheperd probed her on was it a bio weopon if i ever can find the footage she dodges that question not flatly denying or answering if it has come out of a lab
