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. The methods used to calculate these estimates are described on CDC’s webpage, How CDC Estimates the Burden of Seasonal Flu in the U.S."[1][2][3]
The tables below include the latest available years the CDC has provided on their website.[1]
