That's completely wrong. The RT-PCR test triggers based on the presence of nucleic acid sequences unique to SARS-CoV-2. It doesn't "look for symptoms", whatever that means. You take a sample of material from the nasal cavity and test to see whether RNA which is only found in the SARS-CoV-2 virus is present. That's how it works.
"Again you are mixing and matching the numbers. It 99.97% in the United States."
Wrong. Here is the current Pandemic Planning Scenario guide which stratifies IFR into different age groups. If you then weight those age group IFRs against the US population statistics from the US Census Bureau, you find an IFR of ~1%. If you go back to the previous Pandemic Planning Scenario guide (before the IFR was stratified), you see it was listed at 0.65% for the entire US population as a whole.
Hence, 0.65% - 1% IFR for the US population. Or 99% - 99.35% survival rate.
The Food and Drug Administration is still admitting that SARS-CoV-2 has NOT been isolated. So does it even exist?

In the U.S. it is 99.97 percent under age 70. Under age 20 it is 99.997 percent or a statistical zero in other words.
