Good Morning @nadia and All!
I guess that I can help by bringing to the community some experience from acting at the interface to science. Example: I noticed how difficult it is to understand ‘exponential growth’ or making conclusions having only some observations of a highly dynamic and heterogenic process.
Here a video[explaining exponential growth(https://www.youtube.com/watch?v=Dcrzn6qoAec&feature=youtu.be&fbclid=IwAR0rI-cLP4ZY4hpvIzmBc5-mmcXZhv1auE7rAmDl1TfygIjOwu1LOCItRbY). The video explains growth rates and how to get reliable numbers from observations.
Here a map (the region where I live) that shows the spacial coverage at two levels of administrative entities (scroll map). The population between entities at the same level may vary by factor two but case numbers vary more. The structure of the public health system is the same. Hence, the differences in cases show differences in detecting them.
best regards,
Martin
