The 1918 flu pandemic, commonly referred to as the Spanish flu, was a category 5 influenza pandemic caused by an unusually severe and deadly Influenza A virus strain of subtype H1N1. The difference between the influenza mortality age-distributions of the 1918 epidemic and normal epidemics.

US influenza statistics by flu season. From the Centers for Disease Control and Prevention page called "Disease Burden of Flu": "Each year CDC estimates the burden of influenza in the U.S. CDC uses modeling to estimate the number of flu illnesses, medical visits, hospitalizations, and deaths related to flu that occurred in a given season.
