United States influenza statistics by flu season
US influenza statistics by flu season. From the Centers for Disease Control and Prevention page called "Disease Burden of Influenza": "Each year CDC estimates the burden of influenza in the U.S. CDC uses modeling to estimate the number of influenza illnesses, medical visits, flu-associated hospitalizations, and flu-associated deaths that occur in the U.S. in a given season. The methods used to calculate these estimates are described on CDC’s webpage, How CDC Estimates the Burden of Seasonal Influenza in the U.S."[1][2]
