First of all, do you actually have any evidence that there were fewer flu cases this winter? Or is it just an assumption?
Genuine question - I haven't seen the numbers. What I have seen is quite a few friends getting flu like symptoms but testing negative for COVID - which implies to me the common flu is still around.
Secondly, let me assume you are correct and there have been less flu cases. There are a few possible explanations:
Considering that, it is a pretty large jump to go straight to the "COVID isn't real its just flu" conspiracy theory.
- The social distancing etc measures we have for COVID also helps with the flu (sure, it isn't going to prevent it all, but you can't possibly claim there is no impact at all).
- The very fact that people just aren't out and about as much as they usually are would have reduced the spread too.
- It is my understanding that we had a larger uptake of the flu jab this year (which is why it was difficult to get for some groups of people who aren't priority for it).
So I will ask - is there any evidence at all to suggest that flu cases are being reported as COVID cases to spread fear (as was originally being claimed in the post I replied to)?
I wouldn't rule out the prospect that some flu infections are being logged as covid ones, however the basic reproduction number of seasonal flu seems to be much lower than Covid: according to journal articles found via Wikipedia as a central point, seasonal flu is around 0.9-2.1, while Covid is estimated at around 3.28-5.7. Therefore the social distancing measures may actually be very effective at controlling flu due to it being less infectious, but for Covid it's much harder to control and can still spread at an increasing rate. There has also been debates about whether in a majority of cases Covid can block out flu strains while infecting a host, but even without that the R0 values alone seem a plausible enough explanation to why we don't hear as much about flu currently.Well there needs to be an explanation of why flu has gone down to practially zero in comparitive terms, not just in the UK but the whole world.
Whilst there is no scientific explanation being made public, then the theory of flu being mis-reported (intentionally or not) as COVID should be on the table.
If there is a scientific explanation, then this is good news - the usual flu death burden can be taken off the expected COVID death burden and the outcomes in general look a lot better...
Edit: In response to your question above, the flu data is here: https://www.who.int/influenza/surveillance_monitoring/updates/2020_12_21_surveillance_update_383.pdf (page 3 for the graph for the northern hemisphere).
For comparison, here is a report from Jan 2020: https://www.who.int/influenza/surve...s/2020_01_06_surveillance_update_358.pdf?ua=1
