My father was born in 1918. My grandmother being pregnant at the time with him. The flu epidemic struck everywhere and the countryside is filled with tombstones dated 1918. My Grandmother moved all the children and farm workers who were extremely ill from this flu in to a large front room parlor and turned it in to a hospital ward. They even had a couple of neighbors who arrived needing care. Those who were well tended the sick. Everyone in their household managed to survive, but others in the community weren't as fortunate.
The same strain has now been identified.
What did your grandmother do that the rest of the country didn't?
My mother was born in 1917 and my father in 1918. We have no input about whether they had the flu but both lived to an old age.
