It's interesting @A_Freeman brings this up, because according to Freedom of Information Requests, neither the PHE in the UK or CDC in the USA, have documentation of isolating it.
Every object that exists can be quantified, which is to say, measured. The use of the term “quantified” in that phrase means: the CDC has no measurable amount of the virus, because it is unavailable.
You what are the known-flawed PCR Test measuring? –
