"It struck in the Pittsburgh area in October and November of 1918 and claimed 4,500 lives. Some 22,000 cases were recorded.
In October 1918, new cases were reported in the hundreds daily and deaths numbered 175 per day. The epidemic surged to a peak around the end of October and then, gradually, the number of cases began to fall.
No one at the time knew that a virus caused influenza. Sadly, in Pittsburgh, 700 children became orphans as a result of the epidemic.
My uncle died in 1918 of it too...he was a West Point Cadet...about as hardy and hale as one could get.
