So you come up with every possible scenario and then you use hypothesis testing evidence to eliminate hypothesis or scenarios.

So we're now at the stage where this could be a few different things.

One, it could have been a pure accident scenario.

accidental release from the Wuhan laboratory.

And if it's that scenario, it looks like it was a laboratory employee, potentially a graduate student who had been working in that laboratory.

It could have been... Who became infected and then spread it unknowingly... Correct.

...to the world.

So that is, I think, the scenario which has the most favor publicly among experts who are now committed to the fact that this is a laboratory leak.

It could have been an intentional release that still hasn't been eliminated.

One or multiple groups could have intentionally released the agent there.

There's one troubling aspect of this is that there are types of studies or scientific studies which we could have ran to conclusively identify the origin of the disease in space and time.

And this is a classic epidemiological method.

There are blood banks and historical records of disease through blood donation programs globally.

That's right.

So what we do is we go to those blood banks, look at old samples, or we look at other tissues or samples that have been collected.

As they did with HIV.

And then you look through, okay, is it in this location here?

What time?

When?

And then now with modern technology, you can actually use more genetic applications to look at the...
