Clinical Information
  • A disease of the nervous system caused by the rabies virus. Rabies is marked by an increase in saliva production, abnormal behavior, and eventual paralysis and death.
  • A life-threatening viral infection caused by the neurotropic rabies virus. It is transmitted to humans usually from a bite by an infected dog. The initial signs and symptoms include malaise, fever, and headache, followed by the central nervous system manifestations which include abrupt behavioral changes. Paralysis, lethargy, and coma follow the behavioral changes.
  • Acute infectious disease of the central nervous system affecting almost all mammals, including humans; it is caused by a rhabdovirus and usually spread by contamination with virus-laden saliva of bites inflicted by rabid animals; important animal vectors include the dog, cat, vampire bat, mongoose, skunk, wolf, raccoon, and fox.
  • Acute viral cns infection affecting mammals, including humans. It is caused by rabies virus and usually spread by contamination with virus-laden saliva of bites inflicted by rabid animals. Important animal vectors include the dog, cat, bat, fox, raccoon, skunk, and wolf.
  • Rabies is a deadly animal disease caused by a virus. It can happen in wild animals, including raccoons, skunks, bats and foxes, or in dogs, cats or farm animals. People get it from the bite of an infected animal. In people, symptoms of rabies include fever, headache and fatigue, then confusion, hallucinations and paralysis. Once the symptoms begin, the disease is usually fatal. A series of shots can prevent rabies in people exposed to the virus. You need to get them right away. If an animal bites you, wash the wound well; then get medical care. To help prevent rabies
    • vaccinate your pet. Rabies vaccines are available for dogs, cats and farm animals
    • don't let pets roam
    • don't approach stray animals. Animals with rabies might be aggressive and vicious, or tired and weak
