“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.
It's a government agency, what do you expect? Let's give them another 8.5 billion.
The operative word is "has resulted". Actual flu probably kill relatively few. But flu sometimes leads to other diseases, such as pneumonia, that result in death.
