The CDC is admitting the virus hasn't been isolated. In other words, its existence is unproven.

You need to realize the CDC, during its own published confession (see below), is discussing this explosive situation in the context of instructing the world how to perform the PCR test.

The test to detect a virus that isn't there.

This would be on the order of NASA issuing a guide for navigating a fleet of ships to a planet whose existence has not been established—and the population of the whole world is going to board those ships for the voyage.

The CDC is saying: here is how you detect the virus in a human, here is the test on which we're going to rely, here is the test on the basis of which we're going to identify all case numbers and demand all lockdowns—except we don't have the virus.
