Figure 1. — Model diagrams for the human and mosquito components of the model. Red arrows indicate sequential transmissions into a co-infected state, while blue arrows indicate co-transmissions into a co-infected state. Superscripts refer to co-transmission (C) or sequential transmission (S); co-transmission can occur to susceptible or exposed individuals. Subscript ‘12’ refers to co-infection, and ‘1,2’ refers to secondary infection with the second virus following recovery from the first. Compartments are coloured by state.
