Were the Festival Week and the Laurenzi Fair sources of infection?

In the marquee you are close to each other, you sway, sing, sometimes share a beer. All of this makes up the charm of folk festivals – but that also makes folk festivals a good opportunity to get infected with Corona.

It is striking that the incidence in Main-Spessart skyrockets regarding a week following the end of the Laurenzi fair.
