I'm not clear on why medical records are so sensitive. I can understand some people might want to hide HIV status - but is there anything else? In the US people have wanted to hide prior conditions from insurance companies, but I wouldn't expect this a problem in Sweden.
Quite something that we are now at the part of the privacy debate where the argument is "well, why do you care about private medical records? shouldn't this be public?"
Kind of a rough argument, but maybe it's just because they have never been beaten or harassed over something about their medical history. Which is good for them, but not the world most of us live in.
