I wonder what the explanation is for so many of one class's students -- from one of the nicer areas of Malmo -- being sick from school all at once at this time of year. The municipality and school authorities haven't said anything about it publicly as far as I know. And I doubt the public silence so far has anything to do with privacy, as schools and even preschools aren't all that shy about informing the classes/groups/parents when they've had a "winter vomit" outbreak or hair-lice outbreak at the facilities. The symptoms exhibited are very much in keeping what would be expected from COVID-19 hits or some other respiratory/vascular infection.

I am curious about the level of reliability of the more common Covid-19 tests given in Sweden and how the reliability of the Swedish testing compares to that of the testing being done in the neighboring areas. Is there any study that compares the reliability of Swedish testing results to the reliability of its neighbors' testing results?
