Mean (±s.e.) percentage reduction in PCI after 1 year for simulated ‘fast’ and ‘slow’ transmitting pathogens on the northern Tanzania cattle multiplex network for two types of intervention (market movement ban or vaccination at 70% coverage) applied using six strategies: applied to all wards; targeted to 5% (n = 20) of wards using each of three network centrality measures (betweenness, degree and eigenvector centrality); targeted to the 5% of wards with the highest cattle population size; and applied to 5% of wards selected randomly. The greater the reduction in PCI, the more effective the intervention is at reducing the total number of cases. Mean PCI under each scenario is calculated as the geometric mean of 237 simulated epidemics (full data: electronic supplementary material, tables S3 and S4).
