Graphical scheme of the epidemic model.
Compartments included in the model are: susceptible S, uninfected individuals, exposed E, individuals who are not yet contagious, infectious with compliant behaviors IC, who mitigate the spreading of the disease by adopting NPIs, infectious with non-compliant behaviors, or risk-denier infectious ID, individuals who are not compliant with mitigation rules, hospitalized H, people who require hospitalization, self-isolating or quarantined Q, infectious individuals who stay at home and are compliant with NPIs, recovered R, people who are no more infectious. Model parameters are: force of infection λ, incubation rate σ, recovery rate γ, recovery rate for hospitalized patients γhosp, hospitalization rate δ, quarantine rate η, fraction of risk-deniers α, fraction of population that needs hospitalization a and fraction of population that are quarantined at home b.
