I'd like to analyze the development of COVID-19 cases in Austria by state, in respect to the designation of "risk areas" as defined by the Federal Foreign Office of Germany. According to that definition, "risk areas" are areas with "more than 50 new infections per 100,000 inhabitants in the last seven days" (PDF file provided by Robert Koch Institute). So, to assess if an austrian state may be in danger of being declared a "risk area", one has to compute the count of new infections in relation to the total population.
I've found a page that analyzes the case counts per state (coronatracker.at), but they don't provide raw data and they don't compute the count of new infections per seven days retrospectively.
So, does anybody know if there a dataset of new infections per austrian state for the (let's say) last three months?
