Considering the PCR test results are fake, and the nasal swabs are +/-, does anon have insight on how the so called Delta variant is actually being detected/measured?

Saw a news report from FL earlier indicating the city was sampling the wastewater treatment plant and extrapolating their findings in the sewers bavk to the population? Is this really the process?

If PCR is a dud, then how are all these variants being differentiated?
