I appreciate you saying your opinion is anecdotal. In my anecdotal experiences in the hospital over the last year, I can confirm that influenza cases are down. I can also confirm anecdotally that when I was tested in a drive up site for COVID in Oct, I was also tested for influenza.
For some hard data, the CDC reports 524,037 influenza tests since September in the US. That is not a significant reduction in the amount of tests as compared to normal. For comparison in 2019 for the full season 1,145,555 tests were performed.
Positivity rates are also charted, in 2019 the positivity rate was around 15 percent. This year the positivity rate is hovering at 0.2 percent. This information would imply that influenza is almost certainly not as prevalent this year. The reasons for that could be attributed to many factors, but the most likely seems to be an increase in the things I mentioned earlier. The reason COvId is so prevalent despite those efforts seems to be that it is airborne, and influenza is not. Therefore our measures work well in reducing influenza spread, but not as well at COVID.
