4. Estimated Range of Annual Burden of Flu United States, 2010-11 through 2022-23 Influenza Seasons The burden of influenza disease in the United States can vary widely and is determined by a number of factors including the characteristics of circulating viruses, the timing of the season, how well the vaccine is working to protect against illness, and how many people got vaccinated. While the impact of flu varies, it places a substantial burden on the health of people in the United States each year. CDC estimates that from 2010- 2023, influenza has resulted in between 9.3 million 41 million illnesses, between 100,000 710,000 hospitalizations and between 4,900 51,000 deaths annually. https://www.cdc.gov/flu/about/burden/index.html Influenza Division
