Diagram showing compartments in the transmission model (boxes) and transitions between compartments (solid arrows). Dashed arrows show births and deaths. PI = persistently infected, Non-PI = not persistently infected, V = vaccinated, S = susceptible, E = exposed (pre-infectious), I = Infectious and R = recovered. Dotted lines animals in one compartment infecting animals in another compartment. See section “Dynamic Brucellosis models” for more details
