Before revision:  The model is calibrated on hospitals' data , number of deaths, nursing homes ' tests and serological tests.
After revision:  The model integrates social contact data and is fitted on hospitalisations data (admission and discharge), on the daily number of covid-19 deaths (with a distinction between general population and nursing homes related deaths) and results from serological studies. The sensitivity analysis of the estimated parameters relies on a Bayesian approach using Markov Chain Monte Carlo methods.
