Some of the praise of Sweden is a bit misleading. They are still experiencing growth in cases and growth in deaths. The nature of their demographics, high proportion of people live alone, pop density etc seems to have just meant they had to implement fewer measures compared to some other countries. They have one of the worst death rates per million people, in the top ten worse affected countries, far higher than the neighbouring countries, bar the Netherlands who also had a softer approach. I should think at some point they will have to implement tougher measures to bend the curve and not overwhelm their healthcare system (in fairness I think they acknowledge it's early days and this may happen, from what I have read). Of course, they have the advantage of having further measures in their arsenal.
