Proposed models for Medic, Boonah, Devon and Manuka.
The compartments of the models are shown for group i (i=1 (crew); i=2 (passengers)). The population is separated into those who are susceptible (Si), exposed (Ei), asymptomatic (A1i, A2i), pre-symptomatically infectious (IiP), mild (Mi) and severely (IiS) infectious, mild and severely infected (CMi, Ci), severely infectious/infected and quarantined (), and recovered (RAi, Ri, AiQ). The force of infection, λi has terms for both within- and between-group transmission.
