Snippet: The model describes the epidemic dynamics of COVID-19 in a population where hosts can belong to five states: susceptible (S), latent i.e. infected but asymptomatic and not infectious (E), asymptomatic infectious (A), symptomatic infectious (I), recovered (R) and dead (D). Recovered hosts are assumed to be immune for life. The model is also structured by differential disease severity, since COVID-19 can cause both mild or severe infections [19, 26.....
Document: The model describes the epidemic dynamics of COVID-19 in a population where hosts can belong to five states: susceptible (S), latent i.e. infected but asymptomatic and not infectious (E), asymptomatic infectious (A), symptomatic infectious (I), recovered (R) and dead (D). Recovered hosts are assumed to be immune for life. The model is also structured by differential disease severity, since COVID-19 can cause both mild or severe infections [19, 26] . We assume that severe symptomatic infections (I s ) require hospitalisation, which reduces their contagiousness. The main variables and parameters of the model are listed in Table 1 and shown in Figure 1 . The case-fatality ratio (θ) and the basic reproduction number (R 0 ) of the epidemic are known from the literature [5, 6, 16, 25] . From these, we can calculate the disease-induced mortality (α) and the transmission rate, assuming β A = β I , from the following equations:
