Schematic representation of the compartmental model: Individuals start as susceptible (S) and can become exposed to the disease (E) when interacting with infected individuals (Ip,Ia,Ims and Iss). After a latent period, exposed individuals enter a pre-symptomatic phase (Ip), after which they can either become symptomatic (Ims and Iss) or remain without symptoms (Ia). Symptomatic individuals can develop mild symptoms (Ims) or severe symptoms (Iss). When symptoms are severe, they are hospitalized (H). The final outcome of infected individuals is either recovery (R) or death (D)
