Schematic overview of the flows of individuals in the compartmental model: Following SARS-CoV-2/COVID-19 infection susceptible individuals ($S$) move to an exposed state ($E$) and after a latent period individuals further progress to a pre-symptomatic state ($I_{presym}$) in which they can infect others. Consequently, individuals stay either completely symptom-free ($I_{asym}$) or develop mild symptoms ($I_{mild}$). Asymptomatic individuals will recover over time. Upon having mild symptoms, persons either recover ($R$) or require hospitalization (going from $I_{sev}$ to $I_{hosp}$ or $I_{icu}$) prior to recovery ($R$) or death ($D$).
