Also, from the CDC webpage where I got the graph above, they noted: “Weekly mortality surveillance data include a combination of machine coded and manually coded causes of death collected from death certificates.
Here’s a graph for the US as a whole showing the percentage of all deaths that supposedly came from pneumonia or influenza: During flu season last year, it peaked at around 8% share of deaths.
This reporter and this reporter, using CDC numbers, found a much lower number for Florida pneumonia and influenza deaths — still significantly higher than previous years, but not by nearly as much as the tweet above indicates.
In at least a few states, though, it appears that the specific data confusion is that covid-19 deaths are being counted as pneumonia.
The general take-home point: Official covid-19 death counts are really high (107,000 and counting in USA), but the actual numbers are probably much higher than the official counts.
