The CDC on its website has publicly admitted that nobody has isolated COVID-19
"The analytical sensitivity of the rRT-PCR assays contained in the CDC 2019 Novel Coronavirus (2019-nCoV) Real-Time RT-PCR Diagnostic Panel were determined in Limit of Detection studies. Since no quantified virus isolates of the 2019-nCoV are currently available, assays designed for detection of the 2019-nCoV RNA were tested with characterized stocks of in vitro transcribed full length RNA..."
This means that nobody has proven, or can they prove that it even exists. But they designed tests to detect something that hasn't been isolated and isn't available to test.
Everything that we know that exists can be quantified or measured. What CDC is admitting here is that it has no measurable amount of the CoVID that every psychopathic authoritarian has used for justification to shut down the world's economy.
They're saying it's unavailable! They're saying they don't have it! They can't prove its existence!
