The VAST majority of deaths there are people over 70, and Sweden like the US warehouses old people in cramped retirement homes where the virus can spread rapidly regardless of the public health approach outside. Their deaths fell off precipitously once vaccines got to the old.
The lesson here seems to be that nursing homes probably cause some amount of excess mortality, and need special attention during epidemics/pandemics.
Yes, very different. Starting in the 90's Norway started transitioning from large crowded buildings with long corridors to more home based care and other approaches that seek to keep people out of settings that look like nursing homes. In southern Europe more people live with family when they're old. This is common in lots of Asia as well. In the US it varies a lot regionally and by income.
The crowding can cause a lot of morbidity before anyone knows what's going on or how to treat the new infection. This is what happened in New York, the pandemic ripped through nursing facilities killing thousands of seniors well before any treatment was available.
If things unfold more slowly, you have more time to develop treatments. A lot of the deaths in NYC occurred before we figured out that just laying people on their sides reduced the risk of dying significantly.
Moreover, now that we have the ability to rapidly produce vaccines, it isn't a forgone conclusion that everyone will necessarily "get the virus eventually anyway."
