    • What distinguished this pandemic from all others was the high proportion of deaths among young adults. For a typical influenza epidemic, a plot of age versus death rate is usually U-shaped, meaning that the very young and old are in the high-risk groups. For the 1918 pandemic, the graph was "W"-shaped, with a sharp peak corresponding surprisingly to a high death rate among 15 to 34 year olds (3). Mortality rates were severe, over 2.5%, compared with 0.1% for more modern epidemics. Some isolated populations, such as communities of Alaskan Eskimos, experienced mortality rates above 70%. Most of these deaths occurred in young adults, between 15 and 34 years of age, around 20 times as high as in previous years, with 99% of excess deaths among people under 65 years of age.

    • 18HA0 at a concentration of 10 to 15 mg/ml was used to grow crystals in sitting drops with a precipitant solution of 1.68 M sodium dihydrogen phosphate, 0.32 M dipotassium hydrogen phosphate, and 0.1 M phosphate-citrate, with pH 5. 5 (18).

    • Angles of rotation reported here for the H5 and H9 subtypes are less than those in (21). Our method of analysis, as described in the legend for Fig. 1, was different but reports a similar trend and reveals a rotation for the 18HA0 as seen for the avian subtype.
