The number of H5N1 avian influenza outbreaks that exceed a given outbreak size in the British poultry industry, for European (EU, grey) and basic containment controls (BC, black), before (solid lines) and after (dotted lines) targeted inoculation. (a) Disabling transmissions from the 1195 network hubs (sites with 40+ connections) yields moderate, proportional improvements. (b) Inoculating network hotspots (325 sites under EU controls, 669 under BC) prevents large and medium-sized outbreaks altogether. Sample size: one million outbreaks per simulation.
