Is it Not Conceivable that Since Some of the Earlier PCR Tests Were Calibrated at a Cycle Threshold of Between 35 and 39 (and Hence Picking Up a Fair Number of False Positives; Tiny Fragments of the Virus, Not Enough to Get People Sick or Become Contagious), Perhaps Some of the People Who Had Tested Positive Back Then AND Showed Symptoms Weren't Sick from COVID but Rather from Influenza?

Not completely illogical, is it? I mean, the flu did kind of go on vacation for a while, right?
