You see, Rod Hall the Oklahoma state vet is on the case.
"We just don't want to have the public get any idea that there's anything wrong with continuing to do what they've always done with as far as consuming meat and milk," Hall said.
The actual study is below if anyone wants to take a peek under the covers.
Right off the bat, the obvious problem with the comparison is the flu is only caught 1 every 5-6 years versus Covid's possible multiple times per year.
They then set out to "Based on prior reports, we hypothesized that COVID-19 survivors would have more neurologic health care and incident neurologic diagnoses in the year following hospitalization."
Which is a reasonable thing to check for.
They selected the most common neurologic diagnoses. But...are those the most common Covid diagnoses? Apples to oranges?
Evidently, this is plausible enough to the authors to mention it as a possible limitation to the study (in effect).
