Influenza deaths (always estimated) in the US from 1st Feb - 1st May are just below 6,000, which appears to be very low this year in favor of 'covid-19' which is at 37,308 for the same period, according to CDC (first image). Last year, influenza deaths were over 34,000 (second image) the previous year (third image) over 61,000.
So in order to compare this year's US "Covid/flu" deaths to past years, you'd have to find the same death-certificate data for previous flu seasons, not the end-of-year estimates. Couldn't find those monthly figures for the years in question (UPDATE: found it here - I'll look into it and share the data when I get a chance),
I'm not sure if the data I linked to above can be used for an accurate comparison. Something is funky. For example, here are the mortality numbers for February-April 2018, just on the tail end of the bad flu season:
-all flu deaths (J09-J11): 5324
-all flu and influenza deaths (J09-J18): 19320
The numbers for February-April 2020 (roughly, because the CDC site shows weekly figures, and they don't perfectly line up to the start and end of each month):
-all flu deaths: 5539
-all flu and pneumonia deaths: 67668
So while the flu death numbers are similar for each year, the numbers of pneumonia deaths for 2020 seem way too big (or the 2018 numbers are too small). For example, the total number of flu and pneumonia deaths for 2018 is listed as 59,120, and the total for just over 3 months of 2020 is 80,802, and that's not even counting the deaths listed as Covid-19.
As far as I can tell, the data for 2018 should be complete, and the grand total of deaths from all causes for 2018 from the same data set is 2.8 million, which is average for the U.S. So either the data on the CDC page is all wrong for some reason, or something like 4x the normal number of people were dying of pneumonia in the States in February - before any significant Covid deaths were recorded - which doesn't seem right to me. Am I missing something?
