Plot of Incidence Numbers
Here is a plot for the seven day incidence numbers* for Munich and Passau. Source of the data is the Bavarian state office for health and food safety. Additionally, two lines are added at thresholds 30 (blue) and 100 (red).
The data covers the time between 2020-12-03 and 2023-06-01. As the state office changed their website layout during this period (and I only later integrated a health-check in my script), some data points are missing.
* The seven-day incidence rate shows the number of new coronavirus infections - according to positive PCT and antigen tests - within the past week per 100,000 inhabitants. (Hannah Fuchs, DW, 15.10.2020, Link )
