Article 1 is written by some right wing hack with an agenda.
No doctor would intentionally mis-report the flu as covid. Period. Not for any reason.
When a patient tests + for both covid and influenza both are reported.
It isn't an either or proposition
Even if it was, he doesn't understand how billing for doctors go - way too long and complicated to try to explain here
Article 2:Pull it up and look at the maps for the past 5 years - they are nearly the same
Each flu season is unique.
Some start mid/late September others mid November.
Some have high infection rates others lower infection rates
Most peak in January, others not until March.
Article 3:Not sure what your point is in posting it.
There is one anecdotal story of a guy in early March who tested negative for the flu and couldn't get a covid test which isn't surprising given the timeframe.
The doctor told him he had a "bug" - that term is used colloquially to refer to bacterial and viruses. So technically the doctor was correct though correct in the way you ask me where you live and I say the Untied States. Technically that is correct, you do but it is far from being precise.
Every patient who presents with a similar condition is tested for both covid and influenza
The most reasonable explanation? It is likely a combination of a late onset flu season, fewer cases because people are being more diligent about hand washing and they are wearing masks in public. I would also guess that people with mild cases of the flu are reluctant to go to their doctor's office so in the past more people with mild disease would go in and get tested/diagnosed with the flu while this year they are just staying home unless it gets bad.
