United States alone. In Texas, we have a major epizootic going
on in coyotes in south Texas. It has been spreading so fast
that we initiated a wildlife vaccine campaign last month to try
and control it. We also have an epizootic of fox rabies in west
Texas. Skunk rabies is enzootic throughout the state, as is bat
rabies. The east coast of the United States has a major
epizootic of raccoon rabies that has been going on for several
years. There are several additional enzootics of rabies in the US.
Currently, approximately 20,000 people a year die in India from
rabies. This is due to an epizootic in dogs. There are many
other areas of the world with problems with rabies.
