Figure 1. Expanding-wedge tactic with progressive elimination (9). Numbers represent successive oral rabies vaccination (ORV) zones. Potential savings are assumed for the area of progressive elimination, southern Ontario Province. The rectangle bordering the rabies source (i.e., 5) highlights an area of enhanced surveillance, possible point infection control (PIC) activities, trap–vaccinate–release (TVR) activities, or an ORV zone intended to deter future reemergence of the virus.
