The CDC only had number up to 2017. However I'm guessing that the numbers for 2019 were higher...it was a bad flu season. But certainly no more than 10 to 15 thousand.
https://www.cdc.gov/flu/about/burden/index.html
“CDC estimates that influenza has resulted in between 9 million – 45 million illnesses, between 140,000 – 810,000 hospitalizations and between 12,000 – 61,000 deaths annually since 2010.”
Seems the CDC numbers are inconsistent with the CDC numbers.
