Fig. 2: Model schematic.

Model flow diagram with infection states and rates between them for the stochastic meta-population model. The compartments are S: susceptible to infection, E: exposed, or infected but pre-infectious, P: pre-symptomatic and infectious, I: symptomatic and infectious, A: asymptomatic and infectious, Q: in quarantine, R: recovered and immune. The subscript \(i\) refers to the subgroup. An explanation of the rates is given in the main text, Eqs. (1) and (2) and Table 1.
