One interpretation could be that a large number of vulnerable people escaped death from regular ILIs this European season, only to sadly succome to this pandemic.
If you look at the euromomo information for a country it is averaged across all regions, that includes those regions that started lockdown before severe outbreak, so the spike averages down to be small. I.e. you can’t look at the country info and make conclusions about the severity of the disease.
Do you think that a very mild flu season could possibly have made this outbreak worse?
Euromomo [1] has per country breakdown. While some countries are relatively unaffected (yet?), bringing the average down, some, like Italy, Uk, Spain are way beyond the 2017 peak.
As pointed elsethread, possibly because of lockdown, at least in Italy, the worst has been confined to the northen regions (about one fourth of the population but more than half the confirmed cases). If allowed to spread equally everywhere, the numbers would presumably be higher.

That will be because you are using 1.1.1.1 for your DNS: archive.org has decided to give a bung IP to CloudFlare just because... (personally I think CloudFlare are doing the right thing here - protecting your privacy - unfortunately archive disagree. I think archive are wrong since DNS is often cached which is much the same).
the current number depends on lockdown measures. We didn't have lockdowns in 2016, and it is likely if we didn't have them now we'd be much worse. You can look at the graph for Sweden which decided to only apply mild measures for a comparison which shows this is much worse than the 16/17 flu.
The rest of the reasoning is still correct, and I have heard it pointed out before, though I believe you meant warmer _winter_ :)
