Compendium of Animal Rabies Prevention and Control, 2008

sive encephalitis caused by a Lyssavirus. Although the United States has been declared free of canine rabies virus variant transmission, multiple viral variants are maintained in wild mammal populations, and there is always a risk of reintroduction of canine rabies. 2 All mammals are believed to be susceptible to the disease, and for purposes of this document, use of the term animal refers to mammals. The recommendations in this compendium serve as a basis for animal rabies-prevention and -control programs throughout the United States and facilitate standardization of procedures among jurisdictions, thereby contributing to an effective national rabies-control program. This document is reviewed annually and revised as necessary, and the most current version replaces all previous versions. These recommendations do not supersede state and local laws or requirements. Principles of rabies prevention and control are detailed in Part I; Part II contains recommendations for parenteral vaccination procedures; all animal rabies vaccines licensed by the USDA and marketed in the United States are listed in Part III.
