From: Modelling of paratuberculosis spread between dairy cattle farms at a regional scale
Conceptual model of Map spread in a dairy cattle farm. S, susceptible; R, resistant; T, transiently infectious; L, latently infected; Is, Ic, infectious and subclinically infected vs. clinically affected animals, respectively. Ei, indoor environment in housing i, with i in {1,…,5}(depends on age and season); Eg, general environment of the farm; Eout, outdoor environment of grazing calves; Aj, cows in adult group j, with j in {1,…,5}. Contributions to the environment contamination are represented by dotted lines. Exit rates from each compartment are not represented (adapted from Marcé et al. [30]).
