Classifications in the compartment model. Ovals represent conditions of members of the population. These include: susceptible, latent exposed, infectious who have been identified or are symptomatic and isolated, infectious who have not been identified, and who are pre-symptomatic, asymptomatic, infectious who will be hospitalized as severe or critical, those who are hospitalized but will recover, those who are hospitalized who will succumb, those who recovered, and those who passed away. Solid arrows represent conversions from one state to another, with a fixed rate. Dotted arrows represent infectious interactions that promote conversion from susceptible to latent exposed. Each dotted arrow provides a component \(\frac{I}{N}\) to the conversion rate \(\beta \frac{I}{N}\) for that particular infectious group. \(\beta\) is reduced for isolated individuals compared to pre-symptomatic and asymptomatic spreaders. Rectangular boxes reflect the flow through mediated by dotted arrow input: \(\beta \frac{I}{N}S\).
