This Delta variant is weird. Lots of countries in Europe are doing great. Russia was not doing too bad some time ago. But now it's worse.
UK has a huge spike in infections but virtually no deaths. This is weird, considering it's Delta.
Because you need to factor in human behaviour. It's not weird. It's just that you can't compare country statistics 1:1.
Countries are opening up now which pushes up transmission. People are sick of being in isolation so are starting to take more risks.
Poor countries are less good at testing and reporting statistics.
I am not talking about poor countries.
Most of Europe is currently doing great, some which were pretty bad couple of month ago are doing extremely great.
Look at Czechia/Poland/Hungary/France/Germany/Italy even Ukraine.
The only reason I can see for them doing well is that they got hit hard and reacted to it. Whereas Russia was not hit that hard and relaxed.
In Europe there is only 3 countries which are not doing well - Russia, UR and Spain. And only Russia is doing badly in both in infection and in deaths. Some countries are staring to have a new spike though.
