Due to the difficulty of modelling 1.8 billion individuals this model runs an aggregate SIR model on each patch. Populations travel between nearby patches causing some mixing. Ships and trains are modelled as agent that transport populations. Army camps are models are locations with different contact and transmission odds than the civilian population. The three waves of infection are modelled.
The model can be used to explore questions such as ‘how different would the epidemic have been if there had been no war or the war ended much later?’.
