Jeff gave me an answer that made sense. AV apparently may have taken some precautions when a new sickness seemed to be going around.
For the numbers, unfortunately, it's impossible to relate the two. The recording methods were different. For COVID, ANY trace of it (tested or not, and even if you had just maybe been near someone with it - MN) at death was counted as a COVID death. CDC indicates that only 6% of the total (322k as 1/9/2021) were COVID-Only (19,000). The remaining 303,000 had 1 or more comorbidities, with the average being 2.9 other conditions. In 2009, the 15,000 is H1N1-Only. They didn't add any additional counts due to other conditions like they did for COVID. 60 million cases would definitely increase that number significantly.
