This skips over some parts that are worth mentioning to foreigners, such as the competent contact tracing. An example: A positive test early on Monday led to tracing and testing 750 nth-generation contacts by Tuesday afternoon, across a wide area, and containing the outbreak. An official in the city where my family lives (I am Norwegian, but live abroad) once expressed worry about the poor state of contact tracing. During the preceding day they had 40 new positive tests, and by 9:30 they only had identified the infection source for 38 of them. That is, only 95% of the infections were traced on the same day. This was very bad. A reason to worry.
