I heard that last night from this guy. Looks like he has the same source as yours. We can only hope they are wrong.
Yes, he’s using the same new Lancet paper.
I wouldn’t necessarily extrapolate the death rate of 11% from the 99 patient sample to the full population. Half of those 99 had extensive, long-term exposure to the “wet market” and (I’m guessing here) it may be possible that those people had different reactions from long-term exposure.
