As most are aware, there has been no flu season this year, with many people mistakenly attributing this to Covid control measures (which work for flu but not covid, apparently).

Indeed, the WHO flumart surveillance shows the flu disappeared in late Winter 2020 across all of the Americas and has not yet re-appeared:

Similarly, all of Europe and Northern Africa show an almost complete lack of flu, starting right when the Covid pandemic took off in these regions:

The same is true in West and Southern Asia, as well as Oceania. No flu since early 2020:

But, this is not a truly global phenomenon. The flu has returned in East Asia as well as sub-Saharan Africa.

Could it be a coincidence that these are also the regions which have been completely spared from Covid?

The one area of sub-Saharan Africa which follows the global pattern is Southern Africa - which also happens to account for nearly all Covid deaths on the continent:

So, what is going on? A clue can be found from the CDC's 2009 flu activity report which shows that as soon as pandemic H1N1 emerged, all other flu strains disappeared:

When a novel pandemic virus emerges, it outcompetes similar viruses; Covid outcompeted the flu nearly everywhere - except central Africa and Eastern Asia.

So, it CAN NOT be that masks or other mitigations protected Asia, the only reasonable answer is prior immunity.
