This code will retrieve recent data from the HDX and attempt to fit it to a SIR model using structure created by Milan Batista ( The model is data-driven, so its forecast is as good as data are.

Also, it is assumed that the model is a reasonable description of the one-stage epidemic.

Results are saved in structure res (see function fiVirusCV19 header). Optionally the results may be printed by:
