Before revision: We model the evolution of the covid-19 epidemic in Belgium with an age-structured extended SEIR-QD epidemic modelwith separated consideration for nursing homes .
After revision: Following the spread of the covid-19 pandemic and pending the establishment of vaccination campaigns, several non pharmaceutical interventions such as partial and full lockdown, quarantine and measures of physical distancing have been imposed in order to reduce the spread of the disease and to lift the pressure on healthcare system. Mathematical models are important tools for estimating the impact of these interventions, for monitoring the current evolution of the epidemic at a national level and for estimating the potential long-term consequences of relaxation of measures. In this paper, we model the evolution of the covid-19 epidemic in Belgium with an age-structured extended SEIR-QD epidemic modelwith separated consideration for nursing homes .
