Oral rabies vaccination has contributed to the elimination of the red fox rabies
virus variant and the canine rabies virus variant from several European countries and the United States, respectively, and has helped to prevent any appreciable spread of the raccoon rabies virus variant in the eastern United States (1).
Cases of fox rabies
, once prevalent in west Texas, dropped from 244 cases in 1995 to zero in 2010.

In the past 20 years, vaccine baiting has been quite effective in rapidly limiting outbreaks (called "epizootics," the animal equivalent of epidemics) of raccoon rabies in Ontario and some parts of Florida; of coyote and dog rabies in South Texas; and of fox rabies
in many parts of Europe.
Rabies could be reintroduced through direct reentry of infected animals across land borders, as has happened in eastern Italy with an outbreak of fox rabies
originating from the western Balkan region (1).
