That assumes there is a "deadly virus." Chinese propaganda combined with the natural obscurity and inaccuracy of nucleotide testing. Suffice it to say that most viruses are so subject to confounding that the CDC can't accurately pass a double blind study to distinguish between influenza and rhino virus. Or an auto-immune reaction and hepatitis.
There is a reason the standard for confirming a viral infection is isolation and imaging via electron microscope.
The pandemic is all in our heads and the statistics allow us to deceive ourselves into believing we are evidence-based.
