I’ve read half a dozen or so narratives about how it happened.
It was not at all unusual to wake up in the morning, and appear to be totally healthful and uninfected, and to be dead by nightfall.
Scary stuff. Seriously, Night of the Living Dead seriously scary stuff.
And of course the eggheads, in their determination to do something new and exciting no matter how dangerous, have thawed and resurrected the virus from corpses in far northern climes where they were frozen.
Thanks a lot, idjits!
My grandmother died in late October 1918 as a result of the Flu Pandemic, less than a month before WWI ended in Europe ... my father was five years old. My grandfather, a minister, remarried a few years later. The women he married had lost her husband at an early age ... they both had children from their respective marriages. They in turn had children of their own ... thus a family joke ... my kids and your kids ... are fighting with our kids.
