Figure 5. Oral rabies vaccination (ORV) preventive spread or elimination tactic with eventual progressive elimination (22). The ORV zone of vaccinated animals is intended to prevent spread of the disease beyond the ORV zone; potential elimination is assumed to result from successive baiting campaigns into the infected area. Potential savings are assumed beyond the ORV zone (or within the zone, if elimination is possible); disease spread rates, final distances of infectious impacts, and durations of ORV bait distributions ultimately determine the magnitude of potential savings. PIC, point infection control activities; TVR, trap–vaccinate–release activities.
