The SIR model assumes a well-mixed population to allow transmission and removal to be summarized by global rate equations rather than spatially resolved descriptions. This assumption omits detailed information about contact networks, physical locations, and heterogeneous interactions, treating the population as if everybody effectively sees everybody else.
Conditions: The model is the displayed Kermack-McKendrick SIR system.; The dynamics are represented by global rate equations rather than spatially resolved equations.
