I lived in a town of about 800 people during the onset and first year of the pandemic. More than a dozen people from my town alone were in Lombardy and a couple of the super early outbreak areas of Germany during 2020 sportlov (the break that stpe mentions in parent comment). I knew first-hand a lot of people who were really ill in March and April, though I don't know if it was covid for sure, since our testing was insufficient then. Anyway, yeah, lots of Swedes traveling to the wrong places at the wrong time right then.
