Figure 1.

Effect of farmer type on disease prevalence following a common starting prevalence and a hypothetical awareness-raising event (at time zero). (A) Control effort applied (percentage reduction in transmission rate—β—within the farm in relation to the initial β in endemic equilibrium) as a function of disease prevalence for three different farmer types. The vertical dash-dotted line indicates initial prevalence. (B) Disease prevalence over time within the three farms. In both panels, the gray shaded area indicates the target prevalence level from society's perspective (<2%).
