I think the press got a bit excited about Sweden and I don't really think it is fair. Doing my public health training there, and having lived there I don't really think it is comparable to other counties.
The swedes generally have a lot more trust in their government and their public agencies have a lot more freedom from political intervention. At the start of covid, they issued recommendations that weren't too dissimilar from the UK, self isolate, don't go out other than for essentials, work from home if you can and try to avoid public transport. The difference was they didn't make it law/compulsory, instead leaving it to the judgement of the people. The result seems to be that they ended up with more of a slow burn with the authorities seemingly accepting they aren't going to beat it rather than the peaks and troughs the UK has seen.
Society in Sweden is much more socially distant, very few multi-generational households, and a different attitude to working when unwell; you're essentially treated as a danger if you go to work even with a cold and told to go home.
Their public health surveillance is incredible, every test, prescription, medical records, school records and essentially any interaction with the state is recorded and linked to your national insurance number. They even use bots to monitor twitter, newspapers and facebook to look for clusters of people who report not feeling well. The result is data you can trust and usually free from political interference.
The swedish economy has been hit by exports and other impacts, and they openly accept they failed to protect nursing homes (as happened in the UK). I don't think it's fair to slam them, neither do I think it is fair to hallow their actions. It's just different and proof not one size fits all.
