We were being told 2% for so long now. So misapprehensions about under-reporting were not unfounded.
The article is nonsense. How can they know the death rate when they have yet to determine how many have contracted this virus? Answer is they cannot.
It is another in the ongoing attempt to sow panic and crash the world economy.
Actually, the under-reporting is probably people walking around with it who have no or extremely mild symptoms.
I'd guess the mortality rate is around one or lower.
