In total, the CDC estimates that up to 42.9 million people got sick during the 2018-2019 flu season, 647,000 people were hospitalized and 61,200 died. That’s fairly on par with a typical season, and well below the CDC’s 2017-2018 estimates of 48.8 million illnesses, 959,000 hospitalizations and 79,400 deaths.
