That is not necessarily true. Reporting methodology differs a lot between countries.

I would be very cautious about comparing statistics from different countries.

Since they are going for herd immunity in a single phase, it is expected that their rate will be higher. Their curve has started to plateau and they say their strategy is working, https://www.bloomberg.com/news/articles/2020-04-19/sweden-sa...

Though, as that article points out:

1) It's too early to say for sure if it even actually has worked

2) The Swedes are actually staying home and social distancing.

Even if it ultimately does work out for them, that doesn't mean they made the right decision with the data they had. Sometimes people gamble on a long shot and get lucky.

1) This is also true for some US states which are not yet reopening.

2) The Swedes avoided a complete shutdown of their economy. There is similarity between their approach and countries/states which are now reopening, i.e. social distancing and a subset of industry WFH.
