Thanks VR. A couple of things from the Kolata book (I read it when it first came out, it's been a while); the 1918 flu was the worst of, and right in the middle of a five year period of particularly bad flu seasons (1916-1920); also, there was a very bad outbreak in the 1890s, one of the worst ever, but anyone who had that one and survived it never even got the sniffles during the Spanish Lady outbreak.
I had a second cousin who died in 1990 at the age of 90. Both of his sisters caught the flu and died from it a few days apart in early 1920 (in Missouri). I once heard the story of their deaths from him. Even if that wave wasn't as deadly as the second wave, I still don't understand why the deaths in early 1920 are not included in the total usually given for deaths in the US.
