Sweden uses much lighter restrictions with industry still running, most shops still open, and schools for younger children open. One of the keys in this lighter strategy was to protect the elderly, with bans on visits to homes for the elderly and so on. Unfortunately that wasn’t enough, the spread has hit many such facilities with a high number of deaths as a result.

It’s hard to isolate the elderly if they are so old that they need care by the young.

Isolating the not-quite-so-old that can self-isolate is easy.
