Spanish Flu:
“In the U.S., about 28% of the population of 105 million became infected, and 500,000 to 850,000 died (0.48 to 0.81 percent of the population)”

And I suspect "infected" really meant "infected" - i.e., sick with flu-like symptoms. As opposed to this present 'Case' malarkey which means next too nothing. A person can have 'dead' viruses floating around in their system, and exhibiting zero symptoms, and they are counted into the dreaded case number.
This has to be the greatest fraud perpetrated in the history of mankind, while the Global governments work to get everyone under their collective thumbs.
