Excellent read on a sensible approach in Sweden, vs. the rest of Europe
The Swedish laws on communicable diseases are mostly based on voluntary measures — on individual responsibility. It clearly states that the citizen has the responsibility not to spread a disease. This is the core we started from, because there is not much legal possibility to close down cities in Sweden using the present laws. Quarantine can be contemplated for people or small areas, such as a school or a hotel. But [legally] we cannot lock down a geographical area.
Sweden is getting the same result as most of the rest of Europe, only they are doing it without destroying their economy and civil liberties. They also may have obtained herd immunity, preventing another outbreak next winter.
