I don't think the number of deaths in Sweden (around 1500) is that high. Sweden has 10 million people. Some sources report it as 10% (of all cases), but I would be very cautious with these numbers. We know since quite a while that the number of reported cases can only act as an upper barrier, which may be between 10 and 15 times too high.

In Germany you are only tested under some conditions. I know many people that had quite a few symptoms and have not been tested even though they wanted to get a test. Only the ones that got severe problems or had relatives with a positive test. The conclusion is that we only know the death count quite well, the rest is mostly guess work.
