From: Data-driven network modelling of disease transmission using complete population movement data: spread of VTEC O157 in Swedish cattle

Figure 1

Conceptual SIS E compartment model for VTEC O157 in cattle. Schematic representation of a Verotoxigenic Escherichia coli O157:H7 disease spread model in cattle with indirect transmission via the environment and with animal movements between holdings. The model is a SISE compartment model with the environmental infectious pressure compartment (E) and the two disease states susceptible (S) and infected (I). The population is divided in three age categories. *State transitions between the S and I disease states are modelled as a continuous-time discrete state Markov process (Gillespie’s direct method). The other arrows represent state transitions due to scheduled events from livestock data: (†) enter, (‡) ageing, (§) movement between holdings, and (¶) exit.
