Fig. 2 — Workflow design. For a given level of granularity and for each country, the epidemiological data are downloaded from several sources, mapped into a standardized data frame, and merged using the lookup tables. Then, a top-level function collects the data for all the countries at the desired level of granularity. Finally, the epidemiological data are merged with additional covariates and with policy measures. Examples of data sources, variables, and countries are given in parentheses.
