The use of PCR tests to determine viral infection will go down in history as one of the greatest misuses of medical technology ever.

A person's level of viral load that exceeds their immune system's ability to overcome it, is when symptoms appear and actual infection occurs.
Readers will remember the 1973 movie, Soylent Green, staring Charlton Heston and Leigh Taylor-Young, where Sol (Edward G. Robinson) voluntarily reports to an assisted suicide center where he picks the music and scenery to accompany his final exit.
This is the face of Technocracy, aka Scientific Dictatorship. Social engineering and herd management principals are elevated to a status of 'prime directive' and then quietly executed behind the curtain. Now, that curtain is being ripped apart, exposing total disregard for human life and wellbeing.
