The flu epidemic you are talking about killed some 6 million people throughout the world (most figures are given for European Countries as there were no records for Africa etc.) But the death toll was nearly equal to the casualties by all sides in WW1.
The oddity of this outbreak was that it seemed to affect the fit and healthy rather than the v. young and elederly. A figure that springs to mind is that some American units suffered 80% fatalities from the flu. Have a look at the web site for more information.
