Before revision:  I introduce three extensions to these models to fit the daily arrivals in French hospitals, as well in critical care , releases and deaths . These models involve ratios of evolutionary timescales to branching fractions, assumed uniform throughout a country, and the basic reproduction number, R_0, before and during the national lockdown, for each region of France.
After revision:  I introduce three extensions to these models to fit the daily arrivals in French hospitals, as well in critical care , releases and deaths , using extended SEIR models. These involve ratios of evolutionary timescales to branching fractions, assumed uniform throughout a country, and the basic reproduction number, R_0, before and during the national lockdown, for each region of France.
