I recall reading somewhere, that the 1918 influenza was preceded by a less deadly flu in the spring of 1918, and some think it may have mutated into the deadlier one that killed so many people later that year.
My great-grandfather died in the epidemic. Came through the war without a scratch, in his early 20’s, came home, took sick one day in October and died the very next day.
Isn’t it true though that most died of secondary bacterial infections??
Same thing happened to my Grandma's cousin...a nurse in Europe during the war; made it back and died from the flu at the age of 23.
My grandmother died in the 1918 epedemic. She was 25 and my dad was only 3 months old.
