I dunno... it takes some time, according to what I read and was posted on a Q thread IIRC, to de-activate the virus. Not instantaneous.
interesting reading about the 1918(1917) spanish flu.
(Elements of COVID-19 are scary the same)
From https://www.history.com/topics/world-war-i/1918-flu-pandemic
“Almost 90 years later, in 2008, researchers announced they’d discovered what made the 1918 flu so deadly: A group of three genes enabled the virus to weaken a victim’s bronchial tubes and lungs and clear the way for bacterial pneumonia.”
Pres. Trump must be reading the same stuff we are.
Flu brought to the US from WW1 soldiers returning home.
Some reports of the flu in 1917 in canada.

It just didn’t fade away, it drop-dead stopped.
from wiki
“After the lethal second wave struck in late 1918, new cases dropped abruptly – almost to nothing after the peak in the second wave. In Philadelphia, for example, 4,597 people died in the week ending 16 October, but by 11 November, influenza had almost disappeared from the city.”
Pray the likeness stops there and there is no second wave...
