Did Spanish flu mutate?
The influenza pandemic of 1918 was exceptional in both breadth and depth.

Why did the Spanish flu kill so many?
Much of the high death rate can be attributed to crowding in military camps and urban environments, as well as poor nutrition and sanitation, which suffered during wartime. It’s now thought that many of the deaths were due to the development of bacterial pneumonias in lungs weakened by influenza.
