Thats an overlooked point
They “ said” they had no symptoms
However, how could the viral load be high enough to infect others but trigger no response in the host immune system?
And if they were immune ( which some claim is not possible) then how did the viral load in their immune bodies increase and survive for days, to be shed on others?
Suspicion: they had symptoms that were mild enough to deny, pass off as a cold or allergy, or simply treat with OTC meds
“..or simply treat with OTC meds”
I seem to recall folks taking fever-reducing medicine (Tylenol??) so they could get past the thermometers to get on an airplane.
